The effect of subclinical hypothyroidism on hormonal and metabolic profiles and ovarian morphology in patients with polycystic ovary syndrome: a cross-sectional study.

OBJECTIVES: Polycystic ovary syndrome (PCOS) and subclinical hypothyroidism (SCH) are prevalent gynecological conditions. However, the interrelationship between the two remains elusive. This study aims to elucidate the association between these conditions and determine the potential impact of SCH on the physiological and metabolic characteristics of patients with PCOS. METHODS: This cross-sectional study enrolled 133 patients with PCOS from our Hospital. Participants were categorized into two groups: those with PCOS + SCH (n = 58) and those with PCOS (n = 75). Serum hormonal levels, metabolic markers, ovarian volume, and follicle count were compared between the groups. RESULTS: There was a significant difference in BMI between the two groups, with a higher prevalence of obesity in the PCOS + SCH group (p = .014). Compared to the PCOS group, patients with PCOS + SCH had significantly higher levels of TSH (p < .001), triglycerides (p = .025), and HOMA-IR (p < .001), while LH levels were significantly lower (p = .048). However, multivariate linear regression analysis revealed that TSH, triglycerides, LH, and HOMA-IR were not determinants for the occurrence of SCH in patients with PCOS. Additionally, there was a notable reduction in follicle count in the left ovary for the PCOS + SCH group compared to the PCOS group (p = .003), and the overall follicle diameter of the PCOS + SCH group was also smaller (p = .010). CONCLUSION: SCH may exert effects on the physiological and metabolic profiles of patients with PCOS. Further investigation into the relationship between these disorders is warranted to delineate their clinical implications.

Effectiveness of leuprolide acetate administered monthly compared to three-monthly in the treatment of central precocious puberty: evaluation at the end of treatment.

Introduction: Gonadotropin-releasing hormone (GnRH) analogs are the standard treatment for central precocious puberty (CPP). Although there are numerous varieties of GnRH agonists, the effectiveness of 1-monthly compared with 3-monthly Leuprolide acetate is still restricted. The objective of this study was to evaluate the outcomes of CPP treatment with Leuprolide acetate at a 1-monthly dosage of 3.75 mg, in comparison to a dosage of 11.25 mg administered every 3 months. Method: This retrospective cohort study involved 143 girls diagnosed with CPP with 72 of them receiving the monthly treatment regimen and 71 receiving the 3-monthly treatment regimen. Anthropometric measurements were compared at the start and end of the therapy. The rates and level of LH suppression were assessed six months after therapy. Results: The regimen administered every 3 months showed more significant suppression of LH. The 3-monthly group showed lower actual height and degree of bone age advancement at the end of therapy. However, the predicted adult height (PAH) remained comparable in both groups. Conclusion: The 3-monthly treatment showed greater hormonal and growth suppression effects, but there was no significant difference in PAH between the two groups.

Intracerebroventricular PROK2 infusion could increase the secretion of male reproductive hormones by stimulating the HPG axis.

BACKGROUND: Prokineticin 2 (PROK2), an important neuropeptide that plays a key role in the neuronal migration of gonadotropin-releasing hormone (GnRH) in the hypothalamus, is known to have regulatory effects on the gonads. In the present study, the impact of intracerebroventricular (icv) PROK2 infusion on hypothalamic-pituitary-gonadal axis (HPG) hormones, testicular tissues, and sperm concentration was investigated. METHODS AND RESULTS: Rats were randomly divided into four groups: control, sham, PROK2 1.5 and PROK2 4.5. Rats in the PROK2 1.5 and PROK2 4.5 groups were administered 1.5 nmol and 4.5 nmol PROK2 intracerebroventricularly for 7 days via an osmotic mini pump (1 µl/h), respectively. Rat blood serum follicle stimulating hormone (FSH), luteinizing hormone (LH) and testosterone hormone levels were determined with the ELISA method in the blood samples after 7 days of infusion. GnRH mRNA expression was determined with the RT-PCR in hypothalamus tissues. analyze Sperm concentration was determined, and testicular tissue was examined histologically with the hematoxylin-eosin staining method. It was observed that GnRH mRNA expression increased in both PROK2 infusion groups. Serum FSH, LH and testosterone hormone levels also increased in these groups. Although sperm concentration increased in PROK2 infusion groups when compared to the control and sham, the differences were not statistically significant. Testicular tissue seminiferous epithelial thickness was higher in the PROK2 groups when compared to the control and sham groups. CONCLUSION: The present study findings demonstrated that icv PROK2 infusion induced the HPG axis. It could be suggested that PROK2 could be a potential agent in the treatment of male infertility induced by endocrinological defects.

Association among abnormal glycolipids, reproductive hormones, and cognitive dysfunction in female patients with bipolar disorder.

BACKGROUND: Patients with bipolar disorder (BD) show abnormalities in glucolipid metabolism and reproductive hormone levels, which are of concern in women with BD. This study was dedicated to investigating the glucolipid and reproductive hormone levels of female patients, and to preliminarily investigating their relationships with cognition. METHODS: A total of 58 unmedicated female BD patients, 61 stable-medicated female BD patients, and 63 healthy controls (HC) were recruited in this study. Serum glycolipid indexes and reproductive hormones were measured. Cognitive function was assessed using the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) and the Stroop Color-Word Test (Stroop test). RESULTS: Patients with BD showed significant cognitive impairment (p < 0.05), which was not affected by medication. Triglycerides (TG), luteinizing hormone (LH), and high-density lipoprotein cholesterol (HDL-c) were altered in stable-medicated BD patients. In addition, regression analysis showed that progesterone (PRGE) and prolactin (PRL) were negatively associated with cognitive performance in stable-medicated BD patients. CONCLUSIONS: Female BD patients may have cognitive deficits and abnormal levels of glycolipids and reproductive hormones. And abnormal levels of glycolipids and reproductive hormones may be associated with cognitive dysfunction in female BD patients.

The effects of saline water consumption on sperm parameters, testicular histopathology, hormonal and antioxidants concentrations in Barki Rams.

The study aimed to assess the effects of water salinity on the sperm parameters, levels of cortisol, LH, FSH, testosterone and antioxidants as well as the testes' histopathology in Barki rams. Fifteen healthy Barki rams (1-1.5 years) were divided into three equal depending on the type of drinking water for nine months. The rams in the tap water group (TW, water that contained 350 ppm of total dissolved salts (TDS). Males in the high saline water group (HSW) were permitted to consume high saline water with 8,934 ppm TDS, whereas those in the second group were permitted to have moderately saline water (MSW, 4,557 ppm TDS). High salt concentration in drinking water had adverse effect on sperm viability, morphology and sperm cell concertation. Nitric oxide and malondialdehyde concentrations in blood were significantly higher in the MSW and HSW groups than in TW. There was a significant decrease in glutathione concentration as well as superoxide dismutase activity in TDS and HSW. Cortisol was most highly concentrated in the HSW, next in the MSW, and least in TW. The testosterone, LH, and FSH concentrations in the HSW and MSW groups were significantly lower than in TW. As the salt concentration in drinking water increases, damage to testicular tissue. The MSW group demonstrating vacuolation of lining epithelial cells with pyknotic nuclei in the epididymis and necrosis and desquamation of spermatogenic cells in seminiferous tubules while HSW group displaying desquamated necrotic cells and giant cell formation in the epididymis, as well as damage to some of the seminiferous tubules and showed congestion, vacuolation of spermatogenic epithelium of seminiferous tubules, and desquamated necrotic spermatogenic epithelium. In conclusion, the salinity of the water has detrimental impacts on the sperm morphology, viability and concentration, hormones and antioxidant levels in Barki rams.

[Study on mechanism of regulation of sex hormones in treatment of hyperprolactinemia-induced ovulatory disorder infertility with Bushen Culuan Formula].

Transcriptomics was used to investigate the mechanism of action of Bushen Culuan Formula in the treatment of infertility caused by hyperprolactinemia(HPRL), and animal experiments were carried out to verify the results. After establishing an animal model of HPRL-induced infertility, the mice were divided into normal group, model group, Bushen Culuan Formula groups with high-, medium-, and low-doses, and bromocriptine group, and they were observed in terms of the estrous cycle, gonadal index, serum sex hormones, morphology of ovary and mammary gland, follicle count, and fertility. The results showed that the Bushen Culuan Formula could effectively restore the estrous cycle, down-regulate the levels of prolactin(PRL), follicle-stimulating hormone(FSH), and luteinizing hormone(LH), up-regulate the level of estradiol(E_2), increase the number of primordial follicles and sinus follicles, and improve the ovulation rate and fertility of mice. Through RNA sequencing combined with biosignature analysis, Bushen Culuan Formula may regulate the metabolism of lipids, antioxidant enzymes, and other substances in the cells of the ovary and pituitary gland through the signaling pathways of cAMP-PKA, Kiss-1/GPR54, and Hippo and exert therapeutic effects. The results of animal experiments showed that Bushen Culuan Formula could up-regulate serum dopamine(DA) level and pituitary DRD2 expression, down-regulate hypothalamus and ovary cAMP levels, as well as protein expressions of the pituitary gland and ovary PKA, CREB, and p-CREB, and treat HPRL-induced infertility by regulating the cAMP-PKA signaling pathway.

[Bushen Culuan Formula in treatment of infertility caused by polycystic ovary syndrome].

This study aims to observe the efficacy and safety of Bushen Culuan Formula in the treatment of infertility caused by polycystic ovary syndrome(PCOS) and to explore the mechanism using metabolomics. Ninety-four patients with infertility caused by PCOS with the syndrome of kidney deficiency and blood stasis were selected and assigned into treatment and control groups(n=47). The basal body temperature(BBT) was measured, and B-ultrasonography was employed to monitor follicles, ovarian volume, endometrium, ovulation, and pregnancy. The serum levels of sex hormones including follicle-stimulating hormone(FSH), luteinizing hormone(LH), prolactin(PRL), estradiol(E_2), progestin(P), testosterone(T), free testosterone(FT), androstenedione(A2), inhibin B(INHB), and anti-Müllerian hormone(AMH) were measured. The coagulation function, traditional Chinese medicine(TCM) symptom scores, blood and urine routine, liver and kidney functions and other safety indicators were determined. Metabolomics was employed to comparatively analyze the serum metabolites of 26 patients(13 patients in each group) in the clinical study. The results showed that the total response rate and pregnancy rate of the treatment group were higher than those of the control group(P<0.001), suggesting that Bushen Culuan Formula regulated the sex hormones and ovarian function. Specifically, it reduced the levels of LH, T, FT, A2, and INHB(P<0.05 or P<0.01) and the LH/FSH ratio(P<0.05), elevated the level of P(P<0.05), promoted ovulation, increased endothelial thickness, and lowered TCM symptom scores without causing adverse reactions. A total of 24 differential metabolites were screened by metabolomics, and there were correlations between sex hormones and differential metabolites in the PCOS-induced infertility patients with kidney deficiency and blood stasis. In conclusion, Bushen Culuan Formula may regulate hormone levels through lipid and amino acid metabolism.

Microdissection testicular sperm extraction in non-obstructive azoospermic patients with solitary testis: a retrospective case-control study.

Obtaining sperm from the testis surgically and using these sperm with the intracytoplasmic sperm injection technique, has opened the way for the possibility of biological fathering in men with non-obstructive azoospermia (NOA). We aimed to evaluate our sperm retrieval rate (SRR) by microdissection testicular sperm extraction (micro-TESE) in NOA patients with solitary testis. In this retrospective case-control study, fortyfive patients with NOA who had a congenital or acquired solitary testis were included, between September 2003 and January 2022. These patients were randomly matched with patients with NOA who had bilateral testes, using a 1:3 matching ratio. We found that SRR by micro-TESE in patients with solitary testis was similar to NOA patients with bilateral testis (51.1% vs. 50.4%). Age, infertility period, ejaculate volume, serum levels of follicle stimulating hormone (FSH), luteinizing hormone (LH) and testosterone, history of varicocelectomy, history of orchiopexy, testicular stimulation therapy before micro-TESE, testicular volume, genetic status, TESE side, micro-TESE success, complications and histopathological evaluation results of both groups were evaluated, there was a statistically significant difference in only serum FSH and LH levels. There was no difference between the groups in terms of complications and hormonal effects in the early postoperative period. Micro-TESE in NOA patients with solitary testis has similar sperm retrieval and complication rates as NOA patients with bilateral testis.

A dry chemistry-based self-enhanced electrochemiluminescence lateral flow immunoassay sensor for accurate sample-to-answer detection of luteinizing hormone.

BACKGROUND: Colorimetric lateral flow immunoassay (LFIA) is a widely used point-of-care testing (POCT) technology, while it has entered a bottleneck period because of low detection sensitivity, expensive preparation materials, and incapable quantitative detection. Therefore, it is necessary to develop a novel POCT method that is ultrasensitive, simple, portable, and capable of accurately detecting biomarkers in biofluids daily, particularly for pregnancy preparation and early screening of diseases. RESULT: In this work, a novel dry chemistry-based self-enhanced electrochemiluminescence (DC-SE-ECL) LFIA sensor is introduced for accurate POCT of luteinizing hormone (LH). The proposed DC-SE-ECL immunosensor significantly improves the detection sensitivity through the Poly-l-Lysine (PLL)-based SE-ECL probe and cathode modification of closed bipolar electrode (C-BPE). Additionally, a new type of C-BPE configuration is designed for easily performing the LFIA. And, two standalone absorbent pads are symmetrically arranged below the reporting channel of the electrode pad to decease useless residues on the detection pad, which further improves the detection performance. Under optimized conditions, the proposed LFIA sensor has a low limit of detection (9.274 µIU mL-1) and a wide linear dynamic range (0.01-100 mIU mL-1), together with good selectivity, repeatability and storage stability. SIGNIFICANCE: These results indicate that the proposed DC-SE-ECL method has the potential as a new tool for detecting biomarkers in clinical samples.

Involvement of somatotrophic hormones in the postpartum regulation of ovarian activity in mares.

Mares resume ovarian activity rapidly after foaling. Besides follicle-stimulating hormone (FSH) and luteinizing hormone (LH), the pituitary synthesizes prolactin and growth hormone which stimulate insulin-like growth factor (IGF) synthesis in the liver. We tested the hypothesis that follicular growth is initiated already antepartum, mares with early and delayed ovulation differ in IGF-1 release and that there is an additional IGF-1 synthesis in the placenta. Plasma concentrations of LH, FSH, IGF-1, IGF-2, activin and prolactin. IGF-1, IGF-2, prolactin and their receptors in placental tissues were analyzed at the mRNA and protein level. Follicular growth was determined from 15 days before to 15 days after foaling in 14 pregnancies. Mares ovulating within 15 days postpartum formed group OV (n=5) and mares not ovulating within 15 days group NOV (n=9). Before foaling, follicles with a diameter >1 cm were present in all mares and their number increased over time (p<0.05). Follicle growth after foaling was more pronounced in OV mares (day p<0.001, group p<0.05, day x group p<0.05) in parallel to an increase in LH concentration (p<0.001, day x group p<0.001) while FSH increased (p<0.001) similarly in both groups. Plasma concentrations of IGF-1 and prolactin peaked one day after foaling (p<0.001). The IGF-1 mRNA abundance was higher in the allantochorion but lower in the amnion of OV versus NOV mares (group p=0.01, localization x group p<0.01). The IGF-1 receptor mRNA was most abundant in the allantochorion (p<0.001) and IGF-1 protein was expressed in placental tissue without differences between groups. In conclusion, follicular growth in mares is initiated before foaling and placental IGF-1 may enhance resumption of ovulatory cycles.

Cascaded autocatalytic hairpin assembly molecular circuit for amplified fluorescent aptamer luteinising hormone assay.

The quantitative detection of luteinising hormone (LH) is critical for the study of the physiological mechanism of reproductive function and the assessment of infertility and the clinical treatment of reproductive disorders. However, conventional approaches for LH detection are mostly based on an antibody recognition module with the limitations of sensitivity, simplicity and cost. The development of robust LH sensing methods is therefore highly demanded for facilitating the diagnosis of LH-related diseases. We establish a convenient, amplified and sensitive fluorescent aptamer LH assay based on new target-triggered and cascaded autocatalytic hairpin assembly (C-aCHA) circuit amplification means via initiator sequence replication. Target LH molecules bind the aptamers in the aptamer/initiator duplexes to release the initiator sequences, which trigger CHA formation of DNA three-way junctions (TWJs) and the unfolding of fluorescently quenched signal hairpins to show amplified fluorescence. The TWJs further activate another CHA cycle for the yield of more initiator sequences to form the C-aCHA circuit amplification cycles, which lead to the unfolding of many signal hairpins to exhibit substantially magnified fluorescence recovery for detecting LH down to 8.56 pM in the range from 10 pM to 50 nM. In addition, the monitoring of trace LH in diluted serums by this sensing approach has been also verified. Our LH assay clearly outperforms current existing antibody-based methods and the C-aCHA signal amplification strategy can be easily extended as a robust means for sensitively monitoring various biomolecular markers with simple replacement of the corresponding aptamers for diverse applications.

[Ameliorative effect of rare ginsenosides on reproductive injury induced by cyclophosphamide in female rats: based on metabonomics].

Objective: To investigate the effect of rare ginsenosides (RGS) on reproductive injury induced by cyclophosphamide (CP) in female rats. Methods: Twenty-four female rats were divided into four groups [normal control (NC), RGS, CP, and CP+RGS group] with 6 rats in each group. CP group (the model group) and CP+RGS group (the treatment group) were intraperitoneally injected with CP 30 mg/kg for 5 days for modeling, and CP+RGS group was given RGS intragastric intervention. General growth status of rats in each group was observed, the organ index was calculated, and the pathological changes of ovary, uterus, liver and kidney were observed by hematoxylin-eosin staining. Serum levels of estradiol, follicle stimulating hormone (FSH), luteinizing hormone (LH), pro-inflammatory factors interleukin (IL) 6, IL-1ß, tumor necrosis factor-α were detected. The urine samples were collected after RGS treatment for metabonomics analysis. Metabolomic profiling based on ultra performance liquid chromatography (UPLC) coupled with mass spectrometry (MS) was used to analyze and determine the urine metabolites of rats in each group. Results: Compared with NC group, the ovary index of CP group [(0.054±0.015) %] was significantly decreased (P<0.05), the uterus index [(0.293±0.036) %] and estradiol level [(62.9±6.4) pmol/L] were significantly decreased (all P<0.01), serum levels of FSH, LH, IL-6 and IL-1ß [(20.4±1.0) U/L, (29.0±3.0) U/L, (185.4±28.6) ng/L, (72.9±2.0) ng/L, respectively] were significantly increased (all P<0.01). Compared with CP group, the ovary index in CP+RGS group [(0.075±0.010) %] was significantly increased (P<0.05), serum estradiol level [(122.1±16.2) pmol/L] was significantly increased (P<0.01), serum FSH, IL-1ß and IL-6 levels [(16.7±1.0) U/L, (111.8±17.4) ng/L, (60.1±2.2) ng/L, respectively] were significantly decreased (all P<0.01). Metabonomics analysis results showed that, a total of 352 metabolites were detected in urine, of which 12 were found to be potential markers associated with reproductive injury according to the screening standard. After treatment with RGS, differential metabolites were improved in the direction of NC group. Pathway enrichment suggests that the therapeutic effect of RGS was related to multiple metabolic pathways, including purine metabolism and taurine and hypotaurine metabolism. Conclusion: RGS might reduce inflammation and thus ameliorate the damage caused by CP to the reproductive system of female rats by affecting purine metabolism and other pathways.

Assessing the clinical diagnostic value of anti-Müllerian hormone in polycystic ovarian syndrome and its correlation with clinical and metabolism indicators.

BACKGROUND: This study investigated the association between Anti-Müllerian Hormone (AMH) and relevant metabolic parameters and assessed its predictive value in the clinical diagnosis of polycystic ovarian syndrome (PCOS). METHODS: A total of 421 women aged 20-37 years were allocated to the PCOS (n = 168) and control (n = 253) groups, and their metabolic and hormonal parameters were compared. Spearman correlation analysis was conducted to investigate associations, binary logistic regression was used to determine PCOS risk factors, and receiver operating characteristic (ROC) curves were generated to evaluate the predictive value of AMH in diagnosing PCOS. RESULTS: The PCOS group demonstrated significantly higher blood lipid, luteinizing hormone (LH), and AMH levels than the control group. Glucose and lipid metabolism and hormonal disorders in the PCOS group were more significant than in the control group among individuals with and without obesity. LH, TSTO, and AMH were identified as independent risk factors for PCOS. AMH along with LH, and antral follicle count demonstrated a high predictive value for diagnosing PCOS. CONCLUSION: AMH exhibited robust diagnostic use for identifying PCOS and could be considered a marker for screening PCOS to improve PCOS diagnostic accuracy. Attention should be paid to the effect of glucose and lipid metabolism on the hormonal and related parameters of PCOS populations.

Assessment of the Effect of Leonurine Hydrochloride in a Mouse Model of PCOS by Gene Expression Profiling.

Polycystic ovary syndrome (PCOS) is an endocrine disease commonly associated with metabolic disorders in females. Leonurine hydrochloride (Leo) plays an important role in regulating immunity, tumours, uterine smooth muscle, and ovarian function. However, the effect of Leo on PCOS has not been reported. Here, we used dehydroepiandrosterone to establish a mouse model of PCOS, and some mice were then treated with Leo by gavage. We found that Leo could improve the irregular oestros cycle of PCOS mice, reverse the significantly greater serum testosterone (T) and luteinising hormone (LH) levels, significantly reduce the follicle-stimulating hormone (FSH) level, and significantly increase the LH/FSH ratio of PCOS mice. Leo could also change the phenomenon of ovaries in PCOS mice presented with cystic follicular multiplication and a lacking corpus luteum. Transcriptome analysis identified 177 differentially expressed genes related to follicular development between the model and Leo groups. Notably, the cAMP signalling pathway, neuroactive ligand-receptor interactions, the calcium signalling pathway, the ovarian steroidogenesis pathway, and the Lhcgr, Star, Cyp11a, Hsd17b7, Camk2b, Calml4, and Phkg1 genes may be most related to improvements in hormone levels and the numbers of ovarian cystic follicles and corpora lutea in PCOS mice treated by Leo, which provides a reference for further study of the mechanism of Leo.

Diagnosis of Central Precocious Puberty.

A thorough history and physical examination including Tanner staging and growth assessments can guide differential diagnosis and aid in the evaluation of precocious puberty. Basal luteinizing hormone levels measured using a highly sensitive assay can be helpful in diagnosing central precocious puberty (CPP). Brain MRI is indicated with males diagnosed with CPP and females under the age of 6 with CPP. As more information becomes available regarding the genetic etiologies of CPP, genetic testing may preclude the need for imaging studies and other hormonal testing, especially in familial cases.

Dorsal brain activity reflects the severity of menopausal symptoms.

OBJECTIVE: The severity of menopausal symptoms, despite being triggered by hormonal imbalance, does not directly correspond to hormone levels in the blood; thus, the level of unpleasantness is assessed using subjective questionnaires in clinical practice. To provide better treatments, alternative objective assessments have been anticipated to support medical interviews and subjective assessments. This study aimed to develop a new objective measurement for assessing unpleasantness. METHODS: Fourteen participants with menopausal symptoms and two age-matched participants who visited our outpatient section were enrolled. Resting-state brain activity was measured using magnetoencephalography. The level of unpleasantness of menopausal symptoms was measured using the Kupperman Kohnenki Shogai Index. The blood level of follicle-stimulating hormone and luteinizing hormone were also measured. Correlation analyses were performed between the oscillatory power of brain activity, index score, and hormone levels. RESULTS: The level of unpleasantness of menopausal symptoms was positively correlated with high-frequency oscillatory powers in the parietal and bordering cortices (alpha; P = 0.016, beta; P = 0.015, low gamma; P = 0.010). The follicle-stimulating hormone blood level was correlated with high-frequency oscillatory powers in the dorsal part of the cortex (beta; P = 0.008, beta; P = 0.005, low gamma; P = 0.017), whereas luteinizing hormone blood level was not correlated. CONCLUSION: Resting-state brain activity can serve as an objective measurement of unpleasantness associated with menopausal symptoms, which aids the selection of appropriate treatment and monitors its outcome.

Serum gonadal hormones levels and hypogonadism in ART naïve newly diagnosed HIV infected adult males in Mwanza, Tanzania.

BACKGROUND: Human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) is an endemic chronic disease which is characterized with progressive depletion of CD4 T cells and increased susceptibility to opportunistic infections. Previous studies have associated HIV infection with increased hypogonadism. However, the prevalence of hypogonadism remained poorly defined and widely ranging in various studies. This study aims to evaluate the serum gonadal hormonal levels and hypogonadism in antiretroviral therapy (ART) naïve newly diagnosed HIV infected-males in Mwanza, Tanzania. METHODS: This was a comparison study involving 81 ART naïve newly diagnosed HIV-infected adult males as study group and 81 apparently healthy HIV-negative males as comparison group. The participants in the study group and comparison group were matched by body mass index and age. Serum hormones [Total testosterone (TT), follicle stimulating hormone (FSH), luteinizing hormone (LH) and estradiol (E) were estimated. Serum testosterone < 300 ng/dl, or testosterone > 300 ng/dl with high LH and FSH (compensatory hypogonadism) were taken as markers of hypogonadism. Data were analyzed using STATA version 15. RESULTS: The median serum testosterone level among ART naïve newly diagnosed HIV-infected adult males was significantly lower as compared to their comparison group (447 [259-534] versus 517 [396-605]; p = 0.0074) and shown to decrease with decreasing CD4 level. The median [IQR] serum FSH level among ART naïve newly diagnosed HIV-infected adult males was significantly higher than among their comparison group (3.8 [2.1-6.5] versus 2.6 [1.8-4.2]; p = 0.0086). The differences in serum LH and Estradiol were not statistically significant. Furthermore, the proportion of hypogonadism was significantly higher among ART naïve newly diagnosed HIV-infected adult males than in their comparison group (37.0% [30/81] versus 14.8% [12/81]; p = 0.0006). Out of these 30, 24 HIV-infected males had secondary hypogonadism, one had primary, and the remaining five had compensatory hypogonadism. CONCLUSION: Serum testosterone was lower and follicle stimulating hormone was higher among ART naïve HIV-infected males as compared to the HIV negative controls. Hypogonadism, mainly secondary, is common endocrine abnormality among ART naïve HIV-infected male patients in this study. HIV is associated with variations in gonadal hormones which may lead to sexual dysfunction in infected individuals.

Effect of Aqueous Extract of Unripe Musa Paradisiaca Linn on Parameters Affecting Reproduction in Rats.

OBJECTIVE: Aqueous extract of unripe Musa paradisiaca fruit is commonly used for the treatment of ulcers in eastern Nigeria. This study aimed to assess the acute and subacute effects of an aqueous extract of unripe fruit on male and female fertility in rats. METHODS: Aqueous extracts obtained by maceration were analyzed for acute and subacute toxicity and for the presence of phytochemical constituents using standard procedures. The extract (100, 500, and 1000 mg/kg) was administered daily to rats of both sexes for 28 d. Blood samples collected on days 0 and 28 were assessed for follicle-stimulating hormone (FSH), luteinizing hormone (LH), catalase (CAT), superoxide dismutase (SOD), and malondialdehyde (MDA). Testes and ovaries were harvested for histopathological analysis. Sperm were also collected to determine the sperm count and motility. RESULTS: Phytochemical screening revealed the presence of saponins, tannins, alkaloids, and resins. After an oral dose of up to 5000 mg/kg, there were no deaths in the acute toxicity test. The extract (500 mg/kg) significantly (P < .05) enhanced sperm count and motility relative to the untreated control; significantly (P < .05) reduced SOD, CAT, and glutathione levels, while significantly (P < .05) elevated LH, FSH, and MDA levels in male and female rats. Histological examination revealed significant structural damage to the ovaries. CONCLUSION: Unripe Musa paradisiaca fruit exhibited an adverse toxicological profile following prolonged administration and caused oxidative stress in rodents.

Association of lipid profile and obesity in patients with polycystic ovary syndrome.

Objective. Abnormal lipid profile and obesity increase the risk of polycystic ovary syndrome (PCOS). PCOS patients may have a greater risk of infertility, metabolic syndrome (MetS) and cardiovascular disease (CVD) due to abnormal lipid profile and obesity. The aim of the study was to find the association between abnormal lipid profile and obesity in patients with PCOS. Methods. In this case-control study, a total of 102 female subjects (51 diagnosed PCOS and 51 age-matched healthy controls) were enrolled, aged between 20-40 years. Biochemical parameters such as total cholesterol (TC), triglycerides (TG), low-density lipoprotein-cholesterol (LDL-C), high-density lipoprotein-cholesterol (HDL-C), very low-density lipoprotein-cholesterol (VLDL-C), luteinizing hormone (LH), and follicle-stimulating hormone (FSH) were estimated. Anthropometric parameters such as body mass index (BMI), waist circumference (WC), hip circumference (HC), and waist-to-hip ratio (WHR) were recorded. A p<0.05 was considered statistically significant. Results. Mean of BMI, WC, WHR, LH, FSH, TC, TG, LDL-C, and VLDL-C was found significantly elevated in patients with PCOS as compared to controls (p<0.01). However, the mean of HDL-C was found significantly reduced in patients with PCOS as compared to controls (p<0.01). BMI has shown a significant positive correlation with WC (r=0.562, p<0.01) and WHR (r=0.580, p<0.01) among PCOS patients. LH has shown a significant positive correlation with FSH (r=0.572, p<0.01) among PCOS patients. TC has shown a significant positive correlation with TG (r=0.687, p<0.01), LDL-C (r=0.917, p<0.01), and VLDL-C (r=0.726, p<0.01) among PCOS patients. Conclusion. The results showed that abnormal lipid profile and obesity have a significant association with PCOS patients. Regular monitoring and treatment of PCOS patients are required to reduce the risk of infertility, MetS, and CVD.

Reflex strategy to ensure accurate total testosterone results from consumer initiated, self-collected capillary samples.

BACKGROUND: Self-collected capillary samples are convenient for direct access testing (DAT), but exogenous testosterone use may cause falsely elevated total testosterone (TT) results. We designed a quality assurance workflow to differentiate between accurate or erroneous supraphysiological TT concentrations. METHODS: Clinical samples with TT > 1500 ng/dL were reflexed to luteinizing hormone (LH) and follicle stimulating hormone (FSH) and screened for exogenous testosterone use. Samples (n = 120) with normal TT were reflexed to LH/FSH as a control. RESULTS: A total of 8572 TT samples were evaluated, of which 533 (6.2 %) had TT > 1500 ng/dL and were reflexed. Of these, 441 (82.7 %) had significantly decreased LH/FSH (<0.85/<0.7mIU/mL, respectively), 72 (13.5 %) had normal or borderline normal LH/FSH, and 20 (3.8 %) had insufficient plasma volume. In patients with TT > 1500 ng/dL, injectable exogenous testosterone use was most commonly accompanied by significantly decreased LH/FSH, while topical testosterone use was most commonly accompanied by detectable LH/FSH. Control samples were almost all (99.2 %) within or above the LH/FSH reference intervals. Unique patients ordered 351 TT tests where at least one TT result was > 1500 ng/dL. Based on TT and LH/FSH results, we hypothesized that patients were intermittently or consistently overusing exogenous testosterone, resolved elevated TT with recollection, or repeatedly contaminated their sample. CONCLUSION: Self-collected capillary specimens are acceptable for TT testing. A quality assurance reflex to LH/FSH can determine the validity of supraphysiological TT results in a consumer initiated/DAT population.
