Origanum majorana essential oil improves the rat's sexual behavior and testicular oxidative damage induced by imidacloprid via modulating the steroidogenesis pathways.

The neonicotinoid insecticide imidacloprid has been linked to significant reproductive damage in mammals. Origanum majorana essential oil (OME) is a natural herbal product used in the management of many diseases due to its strong antioxidant effects. The oil was hydrodistilled from O. Majorana and analyzed using GC/MS then its possible protective mechanisms against IMI-induced reprotoxicity in male rats were investigated. 28-adult male Wistar rats were divided into 4 groups as follows: group (1) control group, group (2) OME, group (3) IMI, and group (4) IMI + OME. The treatments were applied daily via oral gavage for 60 days. Remarkable abnormalities in both territorial aggressive and sexual behaviors were observed in IMI-treated rats with a significant elevation of serum FSH and LH as well as altered testicular redox status. Along with inhibition of the testicular expression of StAR and aromatase genes and serum total testosterone in addition to abnormal sperm count, viability, motility, and morphology. Histopathological examination showed severe degeneration and necrosis in both germ cells and Leydig cells with atrophy in most of the seminiferous tubules. Co-administration of OME with IMI notably improved all the above-mentioned studied parameters, and restored rats' spermatogenesis, sexual behavior, and favorably modulates the levels of both testosterone and gonadotropic hormones via its potent antioxidant effect. These findings support the use of OME as a fertility enhancer and suggest that it could be used to manage pesticide-induced male infertility.

Influence of human embryo cultivation in a classic CO2 incubator with 20% oxygen versus benchtop incubator with 5% oxygen on live births: the randomized prospective trial.

SummaryOur objective was to assess the effect of benchtop incubators with low oxygen concentrations on the clinical and embryological parameters of our patients. We conducted a prospective, randomized, opened controlled trial on infertile patients in stimulated cycles. In total, 738 infertile patients were assessed for eligibility and, after final exclusions, 230 patients were allocated either to a 5% O2 group (benchtop incubator) or a 20% O2 group (classic incubator). Finally, 198 patients in the 5% O2 group and 195 in the 20% O2 group were analysed. The outcomes measured were fertilization rate, clinical pregnancy rate, and live birth rate. The primary outcome - live birth rate per all transfers - did not show any improvement in the 5% oxygen group over the 20% oxygen group (25.3% versus 22.6%, P=0.531), but the number of day 5 blastocysts was significantly higher (P=0.009). Fertilization rate did not show any beneficial effect of reduced oxygen (5%) (73.4%±22.4% versus 74.6%±24.0%, P=0.606) per all transfers but there was statistically significant difference in the day 5 SET subgroup (85.3±15.1 versus 75.1±17.5; P=0.004). Clinical pregnancy rate showed results in favour of the 5% oxygen group for all subgroups (day 3: 23.7% versus 21.1%, P=0.701; day 5 SET: 35.0% versus 30.6%. P=0.569) but showed statistical significance only in the day 5 SET subgroup (51.1% versus 29.8%; P=0.038). Culturing of embryos in benchtop incubators under low oxygen produced more blastocysts and therefore was a better alternative for embryo selection, which resulted in higher pregnancy rates. To achieve higher live birth rates, embryo quality is not the only factor.

Dietary minerals, reproductive hormone levels and sporadic anovulation: associations in healthy women with regular menstrual cycles.

Although minerals are linked to several reproductive outcomes, it is unknown whether dietary minerals are associated with ovulatory function. We hypothesised that low intakes of minerals would be associated with an increased risk of anovulation. We investigated associations between dietary mineral intake and both reproductive hormones and anovulation in healthy women in the BioCycle Study, which prospectively followed up 259 regularly menstruating women aged 18-44 years who were not taking mineral supplements for two menstrual cycles. Intakes of ten selected minerals were assessed through 24-h dietary recalls at up to four times per cycle in each participant. Oestradiol, progesterone, luteinising hormone (LH), follicle-stimulating hormone (FSH), sex-hormone-binding globulin and testosterone were measured in serum up to eight times per cycle. We used weighted linear mixed models to evaluate associations between minerals and hormones and generalised linear models for risk of anovulation. Compared with Na intake ≥1500 mg, Na intake <1500 mg was associated with higher levels of FSH (21·3 %; 95 % CI 7·5, 36·9) and LH (36·8 %; 95 % CI 16·5, 60·5) and lower levels of progesterone (-36·9 %; 95 % CI -56·5, -8·5). Na intake <1500 mg (risk ratio (RR) 2·70; 95 % CI 1·00, 7·31) and Mn intake <1·8 mg (RR 2·00; 95 % CI 1·02, 3·94) were associated with an increased risk of anovulation, compared with higher intakes, respectively. Other measured dietary minerals were not associated with ovulatory function. As essential minerals are mostly obtained via diet, our results comparing insufficient levels with sufficient levels highlight the need for future research on dietary nutrients and their associations with ovulatory cycles.

Impact of the FSHB gene -211G/T polymorphism on male gonadal function.

PURPOSE: The FSHB gene -211G/T polymorphism has been reported to modulate gene expression and to cause inter-individual differences in FSH serum levels in men. This study was undertaken to assess the functional relevance of this polymorphism on gonadotropin and total testosterone serum levels and sperm parameters in men from Eastern Sicily (Italy). METHODS: To accomplish this, 200 men with abnormal conventional sperm parameters or normozoospermia (according to the parameters of WHO 2010) were genotyped by TaqMan Assay. RESULTS: The frequency of FSHB -211 T allele was significantly higher (p < 0.005) in patients with altered conventional sperm parameters (18.9% of chromosomes) compared to that observed in men with normozoospermia (10.9% of chromosomes). Decreasing serum levels of FSH and LH were observed across the three FSHB -211 genotype subgroups (p < 0.001 and p < 0.05, respectively). In addition, the FSHB -211G/T polymorphism showed a total testosterone downward trend that became more evident in men with the TT genotype compared to subjects with the GG genotype (p = 0.05). Furthermore, we found a trend towards decreased sperm concentration, total sperm count, sperm forward motility and testicular volume in men with GT and TT genotypes. CONCLUSIONS: These findings showed that the FSHB -211 G/T polymorphism modulates male gonadal function with a clear influence on hormonal levels and sperm parameters. CAPSULE: The present study was undertaken to evaluate the distribution of the FSHB -211 G/T in men with normal or abnormal sperm parameters from Southern Italy to assess its functional relevance on the serum levels of reproductive hormones and on sperm parameters in men.

Phenylethanoid Glycosides of Cistanche on menopausal syndrome model in mice.

Cistanche is the traditional and precious Chinese herbal, with two thousand years of use history in China. It has the effect on tonifying kidney, strong supplement to the liver and kidney, and replenishing essence and blood, known as the "desert ginseng". Here, we explored the mechanism of Phenylethanoid Glycosides of Cistanche (PGC) to the model mice of menopausal syndrome, as well as the therapeutic effect and characteristics of PGC to the menopausal syndrome. In this study, KM mice were reproduced by the complete resection of the ovaries on both sides of the back to establish the model mice of menopausal syndrome (MPS), and received distilled water or drugs, respectively. Model mice received distilled water. Mice received 200 mg/(kg day) high doses of Phenylethanoid Glycosides of Cistanche (HPGC), and 100 mg/(kg day) medium doses of Phenylethanoid Glycosides of Cistanche (MPGC), and 50 mg/(kg day) low doses of Phenylethanoid Glycosides of Cistanche (LPGC). After 21 days, it could determine the number of independent activities and the number of standing, the latent period of first entering the dark room, and the electric number. It also calculated the viscera index of uterus, thymus, spleen, measured the levels of estradiol (E2), testosterone (T), luteinizing hormone (LH), and follicle-stimulating hormone (FSH) in the serum. Furthermore, it observed the pathological changes of uterus, thymus, spleen and pituitary of mice. The results showed that behavioral indicators: Compared with the model group (MG), HPGC, MPGC, LPGC could increase the independent activities (P < 0.01); HPGC, MPGC could increase the number of standing, the latent period of first entering the dark room, and reduce the electric number (P < 0.01); LPGC could increase the number of standing (P < 0.05); Viscera index: Compared with MG, HPGC, MPGC could increase the viscera index of uterus, thymus, spleen (P < 0.01); LPGC could increase the viscera index of uterus (P < 0.05); Serum index: Compared with MG, all groups could decrease the levels of LH in the serum (P < 0.01); HPGC, MPGC could improve the levels of E2, T and decrease the levels of LH, FSH in the serum (P < 0.01); LPGC could improve the levels of E2 and decrease the levels of FSH in the serum (P < 0.05). Meanwhile, it had the trend to improve the levels of T in the serum. Pathological changes: Compared with MG, HPGC could significant improve the pathological changes of uterus, thymus, spleen and pituitary of mice; other groups also has a certain effect. The results indicated that PGC could improve the sex hormone disorder of MPS, and restore the function of uterus, thymus and spleen, with better therapeutic effect on MPS.

Outcome of radiotherapy for pituitary adenomas.

AIM: The aim of this study was to analyze the outcome and toxicities and its correlation to patient related and treatment related factors. BACKGROUND: Pituitary adenomas are treated by radiation therapy (RT) as one of the modalities along with surgery and medical therapy. RT to pituitary adenomas is a challenge due to adjacent dose limiting structures such as optic apparatus and hypothalamus. MATERIALS AND METHODS: Between January 2004 and December 2010, 94 patients treated for pituitary adenoma with RT who had hospital records of a minimum follow-up of 1 year were included in the analysis. Tests of correlation were done with regards to treatment factors. RESULTS: Male preponderance was noted in our patient population. Nonfunctioning and functioning tumors were equal in number in this series. Hypopituitarism was associated in 58.5% of patients prior to RT. Radiological tumor progression was seen in one patient (1/94) who had a nonfunctioning tumor. Among functioning tumors, biochemical remission was seen in 93.6% of patients at a median follow-up of 6 years. CONCLUSIONS: Visual complication was seen in 5.3% of patients and worsening or new onset hypopituitarism was seen in 6.4%. Conventional 3-field technique was associated with significantly more visual complication compared to Stereotactic Radiation Therapy (SRT) technique. Doses ≤50.4 Gy showed a trend of reduced rate of visual and endocrine complications with no compromise in efficacy.

Reproductive outcome after in vitro fertilization in endometriosis - key factors and implications.

Endometriosis is a benign chronic disease with a major impact on a woman's quality of life, mainly due to painful physical symptoms. Endometriosis is also a common cause of infertility caused by low ovarian reserve, distorted pelvic anatomy, and severe local inflammation with a direct negative impact on the quality of oocytes, embryos, and endometrium. We conducted a retrospective study between January 2019 and December 2023, including women with a history of surgery for endometriosis who underwent in vitro fertilization (IVF) to achieve pregnancy. Their reproductive outcome was compared with a group of patients with documented tubal obstruction. The aim of our study was to identify the factors associated with a positive impact on the pregnancy rate, specifically age, anti-Mullerian hormone (AMH), ovarian stimulation protocol, and types of gonadotropins used. We analyzed a group of 175 patients with endometriosis compared with 189 patients with tubal obstruction. The average age was similar between the two groups but with a difference in the average AMH value (1.63 ± 1.09 ng/mL vs. 2.55 ± 1.67 ng/mL). The most utilized ovarian stimulation protocol in both groups was the short gonadotropin-releasing hormone (GnRH) antagonist. The clinical pregnancy rate was 27.2% in the endometriosis group and 54.7% in the tubal obstruction group. Our study revealed that treatment with corifollitropin alfa in the endometriosis group was associated with a higher clinical pregnancy rate. AMH and age proved to be significant independent factors for the reproductive outcome.

AMH and other markers of ovarian function in patients with Turner syndrome - a single center experience of transition from pediatric to gynecological follow up.

Turner syndrome (TS) is a chromosomal disorder that affects about 1 in 2500 female births and is characterized by the partial or complete absence of the second X chromosome. Depending on karyotype, TS is associated with primary ovarian insufficiency (POI). Approximately 50% of girls with a mosaic 45, X/46, XX karyotype may enter puberty spontaneously, but only 5-10% of women with TS achieve pregnancy without egg donation. In this review, we will evaluate the clinical use of markers of ovarian function in TS patients. Based on longitudinal studies of serum concentrations of reproductive hormones as well as ovarian morphology in healthy females and patients with TS, we will evaluate how they can be applied in a clinical setting. This is important when counseling patients and their families about future ovarian function essential for pubertal development and fertility. Furthermore, we will report on 20 years of experience of transition from pediatric to gynecological and adult endocrinological care in our center at Rigshospitalet, Copenhagen, Denmark.

Co-occurrence of Functional Gonadotroph Adenoma and Lactotroph Adenoma: A Case Report and Literature Review.

Background/Objective: Functional gonadotroph adenomas (FGAs) are adenomas producing active gonadotropins, follicle-stimulating hormone or luteinizing hormone. Double pituitary adenomas are 2 distinct adenomas occurring in an individual. This report aimed to present an extremely rare case of an FGA, itself an uncommon disorder, co-occurring with a lactotroph adenoma. Case Report: A 33-year-old woman presented with menorrhagia and was found to have ovarian enlargement, large uterine leiomyomas, and bitemporal hemianopsia. Initially, the levels of follicle-stimulating hormone, luteinizing hormone, estradiol, and prolactin were 73.3 mIU/mL (midcycle peak, 2.3-20.9 mIU/L), 3.74 mIU/L (midcycle peak, 8.7-76.3 mIU/L), 1071 pg/mL (midcycle peak 38-649 pg/mL), and 402 ng/mL (2-30 ng/mL), respectively. Pituitary magnetic resonance imaging demonstrated a single sellar mass (2.0 × 2.2 cm). Two months of cabergoline did not reverse visual field deficits; therefore, transsphenoidal resection was performed. Diagnosis of 2 separate adenomas, a gonadotroph and lactotroph adenoma, was confirmed on pathology. Discussion: In this case, gonadotropins did not suppress in response to hyperprolactinemia. Although marked hyperprolactinemia has been associated with functional and clinically silent gonadotroph adenomas in prior cases, this is the first case to confirm an FGA co-occurring with a lactotroph adenoma. Conclusion: In patients who present with elevated gonadotropin levels despite hyperprolactinemia, we suggest considering FGA. Further research is needed to clarify whether there is underdiagnosis of lactotroph adenomas co-occurring with gonadotroph adenomas.

The relationship between hormonal levels and hematological parameters in cystic ovarian syndrome.

Polycystic ovarian syndrome (PCOS) is characterized by the abnormal production of ovarian androgens resulting in elevated levels of male sex hormones in women. This condition is often marked by the development of a group of small cysts, fluid-filled sacs (cysts) in the ovaries. This study aimed to analyze serum levels of prolactin, follicle-stimulating hormone (FSH), luteinizing hormone (LH), and specific hematological parameters in women with PCOS. In total, 70 women were enrolled, of which 50 were diagnosed with PCOS at an obstetrics institution in Karbala from February and May 2022, and 20 were excluded. Participant selection was based on the Rotterdam 2003 criteria, and we excluded postmenopausal women, those with hyperprolactinemia, and those with overt thyroid dysfunction. The control group included 20 fertile women with normal hormone levels, regular menstrual cycles, and no signs of hyperandrogenism, as verified by ultrasonography. Ages 15 to 46 were similar with regard to the frequency of illness, with those under 36 having a higher incidence. Data were collected via questionnaires, hormone level assessments, and complete blood count (CBC) tests. There was a significant increase in hormone levels (LH, FSH, prolactin, TSH) and CBC values (WBC, Hb, and Plt) in the PCOS group compared to the control group. We observed that women between 26 and 35 were more susceptible to PCOS. Furthermore, women who were overweight demonstrated a higher susceptibility to the syndrome.

Zinner's syndrome: Masquerading as pyonephrotic ectopic kidney.

Zinner's syndrome is a rare developmental anomaly of Wolffian duct, comprising a triad of seminal vesicle cyst, ipsilateral renal agenesis and ejaculatory duct obstruction, first described by Zinner in 1914. Several aberrations have been reported like renal dysplasia, ectopic ureteric orifice in one of the derivatives of Wolffian duct. Usually it presents in second to fourth decade of life with symptoms of urinary bladder irritation/obstruction, cyst distension, ejaculatory duct obstruction. The diagnosis is principally based on imaging studies, usually confirmed by MRI. Treatment is based upon the persistent symptoms or complications related to it. Excision of cyst is gold standard.

Effects of combined metformin and cabergoline versus metformin alone on ovarian and hormonal activities in Iraqi patients with PCOS and hyperprolactinemia: a randomized clinical trial.

Polycystic ovary syndrome (PCOS) is one of the most prevalent metabolic diseases during female reproductive life, often associated with insulin resistance and hyperprolactinemia. The efficacy of metformin and cabergoline for managing PCOS remains debated in the literature. This three-arm interventional study in Iraq assessed the effects of these drugs on body mass index (BMI), hormonal balance, and uterine artery blood flow in 75 women with PCOS and hyperprolactinemia. Participants were randomized into three groups: metformin (500 mg twice daily), cabergoline (0.5 mg weekly), and a combination of both, with 25 patients in each group. Baseline and 90-day follow-up characteristics included BMI, serum hormonal levels, and ultrasound features. Metformin resulted in significant weight reduction (p=0.038); however, the addition of cabergoline caused a more significant reduction in body mass index (p=0.001). The combined treatment significantly lowered testosterone levels (p=0.008). In addition, this combination significantly reduced the level of LH (p=0.043) and increased the level of FSH (p=0.047). The results suggest that metformin and cabergoline when used together, act synergistically and safely to reduce BMI, testosterone, and LH levels while increasing FSH levels. Furthermore, this combination improved endometrial blood flow and ovulation in women with PCOS.

Are epigenetic mechanisms and nutrition effective in male and female infertility?

This review discusses epigenetic mechanisms and the relationship of infertility in men and women in relation to parameters pertaining to nutrition. The prevalence of infertility worldwide is 8-12 %, and one out of every eight couples receives medical treatment. Epigenetic mechanisms, aging, environmental factors, dietary energy and nutrients and non-nutrient compounds; more or less energy intake, and methionine come into play in the occurrence of infertility. It also interacts with vitamins B12, D and B6, biotin, choline, selenium, zinc, folic acid, resveratrol, quercetin and similar factors. To understand the molecular mechanisms regulating the expression of genes that affect infertility, the environment, the role of genotype, age, health, nutrition and changes in the individual's epigenotype must first be considered. This will pave the way for the identification of the unknown causes of infertility. Insufficient or excessive intake of energy and certain macro and micronutrients may contribute to the occurrence of infertility as well. In addition, it is reported that 5-10 % of body weight loss, moderate physical activity and nutritional interventions for improvement in insulin sensitivity contribute to the development of fertility. Processes that pertain to epigenetics carry alterations which are inherited yet not encoded via the DNA sequence. Nutrition is believed to have an impact over the epigenetic mechanisms which are effective in the pathogenesis of several diseases like infertility. Epigenetic mechanisms of individuals with infertility are different from healthy individuals. Infertility is associated with epigenetic mechanisms, nutrients, bioactive components and numerous other factors.

Aromatase deficiency in a tall man: Case report of two novel mutations and review of literature.

Aromatase (CYP19A1) is the only enzyme known to catalyse the conversion of androgen to estrogen. Aromatase deficiency occurs due to mutation in CYP19A1gene which has an autosomal recessive inheritance pattern. It leads to decrease in estrogen synthesis and delayed epiphyseal closure, eunuchoid habitus and osteopenia. We are presenting here, a 24 years old male, with history of progressive increase in height and knock knees. X-ray showed open wrist and knee epiphysis. The serum testosterone level was normal and serum estradiol level was undetectable. Semen analysis showed azoospermia. Clinical exome sequencing gave two novel mutations in CYP19A1. The first variant was a novel single nucleotide deletion of thiamine at 570th base of the cDNA (c.570delT) of CYP19A1 gene. The second variant detected was again a novel one in the same gene in Exon 5 corresponding 344th base of the cDNA (c344G>A) resulting in a missense mutation of 115th arginine to glutamine in the protein. Sanger sequencing showed that the later mutation was inherited from the father. The patient was started on oral estradiol valerate for epiphyseal closure to prevent further increase in height. Only 15 mutations have been reported in the aromatase gene in males till date, our report of these novel mutations will be an add-on to the literature.

Combined Central Hypothyroidism and Adrenal Insufficiency Associated with Retinoic Acid Therapy for Cutaneous T-Cell Lymphoma.

Background/Objective: Although retinoid-associated central hypothyroidism has been reported on several occasions, there are very few studies on retinoid-associated central adrenal insufficiency. Here, we present the case of a patient with alitretinoin-induced central hypothyroidism and adrenal insufficiency. Case Report: An 86-year-old man with a diagnosis of cutaneous T-cell lymphoma, treated with oral alitretinoin 30 mg po daily, topical steroids, and ultraviolet light therapy presented to the emergency department with generalized weakness, decreased energy, orthostasis, and unexplained falls. Thyroid-stimulating hormone (TSH) was 0.31 mIU/L (normal range: 0.4-4.4) from 1.93 before alitretinoin therapy, whereas free thyroxine was 5.7 pmol/L (normal range: 8-18) and the AM cortisol was 40 nmol/L (normal range: 120-535); these values were suggestive of central hypothyroidism and adrenal insufficiency. Adrenocorticotropic hormone (ACTH) was not measured because of a laboratory error. Alitretinoin was stopped, and one dose of hydrocortisone 100mg IV was initiated, followed by maintenance doses of oral hydrocortisone 20mg qam and 10mg qpm. Levothyroxine (50µg ) daily was started 24 hours later. After stopping hydrocortisone for 24 hours, the AM cortisol and ACTH levels were 406 nmol/L and 2.18 pmol/L (normal range:1.6-13.9), respectively. He was discharged on thyroid hormone replacement therapy and glucocorticoids. Repeat thyroid function tests 6 weeks later showed a TSH of 0.4 mIU/L, and free thyroxine of 9.7 pmol/L. Discussion: Alitretinoin activates nuclear receptors called retinoic acid receptors and retinoid X-receptors. Retinoic acid receptors and retinoid X-receptors are widely expressed in the anterior pituitary gland. RXR-selective ligands such as retinoids can suppress TSH secretion, resulting in central hypothyroidism. Retinoids have also been shown to decrease ACTH secretion, which can result in central adrenal insufficiency. Conclusion: Although central adrenal insufficiency and hypothyroidism have not been commonly reported in patients taking retinoids, they should always be considered when caring for these patients.

A Case Report of Hyperestrogenism in Prader-Willi Syndrome.

OBJECTIVE: Prader-Willi syndrome (PWS) is associated with multiple endocrinopathies, including hypogonadism. The mechanism underlying hypogonadism in PWS is thought to be secondary to hypothalamic dysfunction, primary gonadal defect, or a combination of both. Here, we present a case of hyperestrogenism in PWS due to concomitant polycystic ovary syndrome (PCOS) and therapeutic considerations regarding hormone replacement therapy (HRT). CASE REPORT: An 18-year-old woman with PWS transferred to adult care from pediatrics was found to have hyperestrogenism (specifically, elevated estrone with normal estradiol levels). Additionally, she demonstrated oligomenorrhea and hyperandrogenism, meeting diagnostic criteria for PCOS. After 3 months of therapy with cyclic medroxyprogesterone alone, she developed normal withdrawal bleeding. DISCUSSION: Given the elevated estrone and normal estradiol levels, our patient's hyperestrogenism is thought to be a direct result of her hyperandrogenism due to peripheral conversion. Prolonged exposure to unopposed estrogen is an established risk factor for endometrial cancer development in PCOS; thus, this was taken into account regarding her HRT, and she was treated with cyclic progesterone alone. CONCLUSION: Women with PWS are typically treated with combined estrogen and progesterone HRT; however, our case, a unique presentation of PCOS in PWS, demonstrated the importance of tailoring HRT to a patient's specific needs.

Microorganisms in the reproductive system and probiotic's regulatory effects on reproductive health.

The presence of microbial communities in the reproductive tract has been revealed, and this resident microbiota is involved in the maintenance of health. Intentional modulation via probiotics has been proposed as a possible strategy to enhance reproductive health and reduce the risk of diseases. The male seminal microbiota has been suggested as an important factor that influences a couple's health, pregnancy outcomes, and offspring health. Probiotics have been reported to play a role in male fertility and to affect the health of mothers and offspring. While the female reproductive microbiota is more complicated and has been identified in both the upper and lower reproductive systems, they together contribute to health maintenance. Probiotics have shown regulatory effects on the female reproductive tract, thereby contributing to homeostasis of the tract and influencing the health of offspring. Further, through transmission of bacteria or through other indirect mechanisms, the parent's reproductive microbiota and probiotic intervention influence infant gut colonization and immunity development, with potential health consequences. In vitro and in vivo studies have explored the mechanisms underlying the benefits of probiotic administration and intervention, and an array of positive results, such as modulation of microbiota composition, regulation of metabolism, promotion of the epithelial barrier, and improvement of immune function, have been observed. Herein, we review the state of the art in reproductive system microbiota and its role in health and reproduction, as well as the beneficial effects of probiotics on reproductive health and their contributions to the prevention of associated diseases.

Rapidly Progressive Precocious Puberty With an Elevated Testosterone Level in a 5-Year-Old Boy With a ß-Human Chorionic Gonadotropin-Secreting Intracranial Germ Cell Tumor in the Pineal Gland.

Objective: Peripheral precocious puberty (PP) is an infrequent etiology for early sexual development. Intracranial germ cell tumors (GCTs) are rare but can present infrequently with PP with the rate of development affected by the degree of tumor hormone production. Our objective was to describe a young boy with a ß-human chorionic gonadotropin (hCG)-secreting intracranial GCT with an extremely elevated testosterone level, who presented with rapidly progressive PP. Case Report: A 5-year-old boy presented with penile growth plus pubic hair, deepening voice, and body odor for 3 months. Physical examination revealed a height velocity of 16.25 cm/year, Tanner stage 3 pubic hair, and enlarged penis for age. Laboratory results revealed elevated serum and cerebrospinal fluid ß-hCG and 17-hydroxyprogesterone progesterone levels. The testosterone level was above the initial detection range at 2700 ng/dL. Follicle-stimulating hormone and luteinizing hormone were prepubertal with normal serum and cerebrospinal fluid alpha-fetoprotein levels. Imaging showed a pineal mass diagnosed as a ß-hCG-secreting GCT. During chemotherapy, the physical signs of PP remitted and laboratory values normalized. Discussion: Intracranial tumors can cause peripheral PP in boys. If the tumor produces high ß-hCG levels, this could cause severe hyperandrogenemia resulting in the rapid development of secondary sexual signs. GCTs should be considered in male patients with rapidly progressive PP, even in those lacking other signs of a brain tumor. Conclusion: When presented with a boy with PP, a GCT should be considered if workup shows an elevated testosterone level in conjunction with an elevated ß-hCG level, especially if with rapid development.

Sparsely Granulated Corticotroph Pituitary Macroadenoma Presenting With Pituitary Apoplexy Resulting in Remission of Hypercortisolism.

Objective: Pituitary corticotroph macroadenomas, which account for 7% to 23% of corticotroph adenomas, rarely present with apoplexy. This report aimed to describe a patient with a sparsely granulated corticotroph tumor (SGCT) presenting with apoplexy and remission of hypercortisolism. Case Report: A 33-year-old male patient presented via ambulance with sudden onset of severe headache and nausea/vomiting. Physical examination revealed bitemporal hemianopsia, diplopia from right-sided third cranial nerve palsy, abdominal striae, facial plethora, and dorsal and supraclavicular fat pads. Magnetic resonance imaging demonstrated a 3.2-cm mass arising from the sella turcica with hemorrhage compressing the optic chiasm, extension into the sphenoid sinus and cavernous sinus. Initial investigations revealed a plasma cortisol level of 64.08 (reference range [RR], 2.36-17.05) mcg/dL. He underwent emergent transsphenoidal surgery. Pathology was diagnostic of SGCT. Postoperatively, the following laboratory findings were found: (1) cortisol level, <1.8 ug/dL (RR, 2.4-17); (2) adrenocorticotropic hormone level, 36 pg/mL (RR, 0-81); (3) thyroid-stimulating hormone level, 0.07 uIU/mL (RR, 0.36-3.74); (4) free thyroxine level, 1 ng/dL (RR, 0.8-1.5); (5) luteinizing hormone level, <1 mIU/mL (RR, 1-12); (6) follicle-stimulating hormone level, 1 mIU/mL (RR, 1-12); and (7) testosterone level, 28.8 ng/dL (RR, 219.2-905.6), with ongoing requirement for hydrocortisone, levothyroxine, testosterone replacement, and continued follow-up. Discussion: Corticotroph adenomas are divided into densely granulated, sparsely granulated, and Crooke cell tumors. Sparsely granulated pattern is associated with a larger tumor size and decreased remission rate after surgery. Conclusion: This report illustrates a rare case of hypercortisolism remission due to apoplexy of an SGCT with subsequent central adrenal insufficiency, hypothyroidism, and hypogonadism.

Intergenerational protein deficiency and adolescent reproductive function of subsequent female generations (F1 and F2) in rat model.

BACKGROUND: Efficient reproductive function is an important characteristic that has evolved through natural selection. Nutrition can modulate reproductive activities at different levels, and its effect on reproduction is deemed complex and less predictable. OBJECTIVE: This study aims at investigating the underlying effect of persistent dietary protein deficiency during early life on reproductive parameters of subsequent (F1 and F2) generations. METHOD: Rats in group of four (4) were fed daily, different ration of protein diet (PD) formulated as: 21% protein diet, 10%protein diet, 5%protein diet and control diet (rat chow, containing 16-18% protein). They were fed ad libitum before mating, throughout gestation and lactation, and next generations were weaned to the maternal diet. Reproductive function analysis (which include; gestation and pubertal hormonal profiling, onset of puberty, oestrus cyclicity, sexual response) and morphometric analysis of the ovarian structure were carried out to assess associated consequences. RESULTS: There was significant reduction in the fertility index (Control; 85.8%., 21%PD; 88.43%., as compared to 10%PD; 65.9%., 5%PD; 35.78%.,) at F1, also recurring in F2 respectively as a consequence of altered reproductive function in the protein deficient models at P ≤ 0.05. Low protein diet posed suboptimal intrauterine condition, which was linked to increased prenatal morbidity and mortality (control; 11.3%., 21%PD; 3.3%., 10%PD; 27.4%., 5%PD; 32.9%), low birthweight (control; 5.29, 4.9 g., 21%PD; 5.5, 5.06 g., 10%PD; 4.05, 3.86 g., 5%PD; 2.7, 2.5 g) at F1 and F2 respectively, delayed onset of puberty (with average pubertal age set at: control; PND 36, 21%PD; PND 38 while 10%PD; PND 62., and 5%PD; PND 67), followed by induced cycle irregularity, altered follicular maturation and endocrine dysfunction, more severe in 5%PD. CONCLUSION: Reproductive status of a female organism depends on the maintenance of ovarian structure and function that has been associated with the hypothalamic pituitary-gonadal axis, hormonal events and sexual maturity. There is therefore an association between persistent early life protein deficiency and reproductive response which mechanistically involves life-long changes in key ovarian cytoarchitecture and function.
