Obstetric and perinatal outcomes in subfertile patients who conceived following low technology interventions for fertility enhancement: a comprehensive review.

PURPOSE: Low technology interventions for fertility enhancement (LTIFE) are strategies that avoid retrieval, handling, and manipulation of female gametes. The definition of LTIFE is yet to be widely accepted and clarified, but they are commonly used in milder cases of infertility and subfertility. Based on these considerations, the aim of the present study was comprehensively to review and investigate the obstetric and perinatal outcomes in subfertile patients who underwent LTIFE. METHODS: A literature search up to May 2017 was performed in IBSS, SocINDEX, Institute for Scientific Information, PubMed, Web of Science, and Google Scholar. An evidence-based hierarchy was used according to The Oxford Centre for Evidence-Based Medicine to determine which articles to include and analyze, and to provide a level of evidence of each association between intervention and outcome. RESULTS: This analysis identified preliminary and low-grade evidence on the influence of LTIFE on obstetric and perinatal outcomes in subfertile women. CONCLUSIONS: LTIFE women should deserve major consideration from Clinicians/Researchers of Reproductive Medicine, because these treatments could be potentially responsible for mothers' and babies' complications. So far, the lack of well-designed and unbiased studies makes further conclusions difficult to be drawn.

Risk of adverse pregnancy and perinatal outcomes after high technology infertility treatment: a comprehensive systematic review.

In the literature, there is growing evidence that subfertile patients who conceived after infertility treatments have an increased risk of pregnancy and perinatal complications and this is particularly true for patients who conceived through use of high technology infertility treatments. Moreover, high technology infertility treatments include many concomitant clinical and biological risk factors. This review aims to summarize in a systematic fashion the current evidence regarding the relative effect of the different procedures for high technology infertility treatments on the risk of adverse pregnancy and perinatal outcome. A literature search up to August 2016 was performed in IBSS, SocINDEX, Institute for Scientific Information, PubMed, Web of Science and Google Scholar and an evidence-based hierarchy was used to determine which articles to include and analyze. Data on prepregnancy maternal factors, low technology interventions, specific procedures for male factor, ovarian tissue/ovary and uterus transplantation, and chromosomal abnormalities and malformations of the offspring were excluded. The available evidences were analyzed assessing the level and the quality of evidence according to the Oxford Centre for Evidence-Based Medicine guidelines and the Grading of Recommendations Assessment, Development, and Evaluation system, respectively. Current review highlights that every single procedure of high technology infertility treatments can play a crucial role in increasing the risk of pregnancy and perinatal complications. Due to the suboptimal level and quality of the current evidence, further well-designed studies are needed.

Pregnancy complications in spontaneous and assisted conceptions of women with infertility and subfertility factors. A comprehensive review.

In the literature, there is growing evidence that assisted reproductive techniques increase the risk of pregnancy complications in subfertile couples. Moreover, many concomitant preconception risk factors for subfertility are frequently present in the same subject and increase the risk of pregnancy complications. This review aimed to summarize in a systematic fashion the best current evidence regarding the effects of preconception maternal factors on maternal and neonatal outcomes. A literature search up to March 2016 was performed in IBSS, SocINDEX, Institute for Scientific Information, PubMed, Web of Science and Google Scholar. An evidence-based hierarchy was used to determine which articles to include and analyse. Available data show that the risk of pregnancy complications in spontaneous and assisted conceptions is likely multifactorial, and the magnitude of this risk is probably very different according specific subgroups of patients. Notwithstanding the only moderate level and quality of the available evidence, available data suggest that the presence and the treatment of specific preconception cofactors of subfertility should be always taken into account both in clinical practice and for scientific purposes.

Progesterone administration for luteal phase deficiency in human reproduction: an old or new issue?

Luteal phase deficiency (LPD) is described as a condition of insufficient progesterone exposure to maintain a regular secretory endometrium and allow for normal embryo implantation and growth. Recently, scientific focus is turning to understand the physiology of implantation, in particular the several molecular markers of endometrial competence, through the recent transcriptomic approaches and microarray technology. In spite of the wide availability of clinical and instrumental methods for assessing endometrial competence, reproducible and reliable diagnostic tests for LPD are currently lacking, so no type-IA evidence has been proposed by the main scientific societies for assessing endometrial competence in infertile couples. Nevertheless, LPD is a very common condition that may occur during a series of clinical conditions, and during controlled ovarian stimulation (COS) and hyperstimulation (COH) programs. In many cases, the correct approach to treat LPD is the identification and correction of any underlying condition while, in case of no underlying dysfunction, the treatment becomes empiric. To date, no direct data is available regarding the efficacy of luteal phase support for improving fertility in spontaneous cycles or in non-gonadotropin induced ovulatory cycles. On the contrary, in gonadotropin in vitro fertilization (IVF) and non-IVF cycles, LPD is always present and progesterone exerts a significant positive effect on reproductive outcomes. The scientific debate still remains open regarding progesterone administration protocols, specially on routes of administration, dose and timing and the potential association with other drugs, and further research is still needed.

Complications and challenges associated with polycystic ovary syndrome: current perspectives.

Polycystic ovary syndrome (PCOS) represents the most common endocrine dysfunction in fertile women and it is considered a heterogeneous and multifaceted disorder, with multiple reproductive and metabolic phenotypes which differently affect the early- and long-term syndrome's risks. Women with PCOS present an adverse reproductive profile, including a high risk of pregnancy-induced hypertension, preeclampsia, and gestational diabetes mellitus. Patients with PCOS present not only a higher prevalence of classic cardiovascular risk factors, such as hypertension, dyslipidemia, and type-2 diabetes mellitus, but also of nonclassic cardiovascular risk factors, including mood disorders, such as depression and anxiety. Moreover, at the moment, clinical data on cardiovascular morbidity and mortality in women with PCOS are controversial. Finally, women with PCOS show an increased risk of endometrial cancer compared to non-PCOS healthy women, particularly during premenopausal period. Currently, we are unable to clarify if the increased PCOS early- and long-term risks are totally due to PCOS per se or mostly due to obesity, in particular visceral obesity, that characterized the majority of PCOS patients. In any case, the main endocrine and gynecological scientific societies agree to consider women with PCOS at increased risk of obstetric, cardiometabolic, oncology, and psychological complications throughout life, and it is recommended that these women be accurately assessed with periodic follow-up.

Cellular angiofibroma in women: a review of the literature.

Cellular Angiofibroma (CA) represents a quite recently described mesenchymal tumour that occurs in both genders, in particular in the vulvo-vaginal region in women and in the inguino-scrotal area in men. The first description of this tumour dates from Nucci et al. article in 1997; since then, the literature reports different reviews and case report of this tumour in both genders, but no article specifically addressing CA treatment and follow-up in women. In this review we collected all 79 published female CA cases, analyzing the clinical, pathological and immunohistochemical features of the tumour.CA affects women mostly during the fifth decade of life, it is generally a small and asymptomatic mass that mainly arises in the vulvo-vaginal region, although there are reported pelvic and extra-pelvic cases. The treatment requires a simple local excision due to an extremely low ability to recurrent locally and no chance to metastasize. Throughout the immunohistochemical and pathological findings it is also easily possible a differential diagnosis from the other soft tissue tumours which affect the vulvo-vaginal area, such as spindle cell lipoma, solitary fibrous tumour, angiomyofibroblastoma and aggressive angiomyxoma.

Myo-inositol modulates insulin and luteinizing hormone secretion in normal weight patients with polycystic ovary syndrome.

AIM: To investigate hormonal dynamics in a group of non-obese polycystic ovary syndrome (PCOS) patients under myo-inositol (MYO) administration. METHODS: Hormonal profiles, insulin response to oral glucose tolerance test (OGTT) and luteinizing hormone (LH) response to gonadotropin-releasing hormone (GnRH) stimulation test before and after the administration of a preparation of MYO (3 g p.o. daily) mixed with lactoferrin and bromelin, in a group (n = 24) of normal weight PCOS patients. RESULTS: After the treatment interval, body mass index (BMI) did not change while LH, LH/follicle-stimulating hormone, 17-hydroxy-progesterone and androstenedione decreased significantly. Insulin response to OGTT was significantly reduced after the treatment interval (P < 0.05) as well as GnRH-induced LH response (P < 0.05). High-sensitivity C-reactive protein decreased significantly after the treatment interval. CONCLUSION: MYO administration positively modulates insulin sensitivity in non-obese PCOS patients without compensatory hyperinsulinemia, improving hormonal parameters. The presence of bromelin in the formulation modulated the pro-inflammatory state that characterizes PCOS, independently of BMI.

Modulatory role of D-chiro-inositol (DCI) on LH and insulin secretion in obese PCOS patients.

Polycystic ovary syndrome (PCOS) is a common endocrine condition that affects fertility through oligo-ovulation, hyperandrogenism and polycystic morphology of the ovaries. Since it has been demonstrated a high incidence of insulin resistance in PCOS patients, our study aimed to evaluate the efficacy of the integrative treatment with D-chiro-inositol (DCI) (500 mg die, per os, for 12 weeks) on hormonal parameters and insulin sensitivity in a group of overweight/obese PCOS patients (body mass index; BMI > 26). After the treatment, interval several endocrine parameters improved (luteinizing hormone [LH], LH/follicle stimulating hormone [FSH], androstenedione and insulin), insulin response to oral glucose tolerance test reported the significant improvement of insulin sensitivity as well as the gonadotropin-releasing hormone (GnRH)-induced (10 µg, in bolus) LH response. BMI decreased, though no lifestyle modification was requested. When data were analyzed according to the presence or absence of first-grade diabetic relatives, PCOS patients with diabetic relatives showed greater improvement after DCI administration. In conclusion DCI administration is effective in restoring better insulin sensitivity and an improved hormonal pattern in obese hyperinsulinemic PCOS patients, in particular, in hyperinsulinemic PCOS patients who have diabetic relatives.

Differential insulin response to myo-inositol administration in obese polycystic ovary syndrome patients.

Polycystic ovary syndrome (PCOS) is characterized by hyperandrogenism, chronic anovulation, polycystic ovaries at ultrasound evaluation, and quite frequently by insulin resistance or compensatory hyperinsulinemia. Attention has been given to the role of inositol-phosphoglycan (IPG) mediators of insulin action and growing evidences suggest that a deficiency of D-chiro-inositol (DCI) containing IPG might be at the basis of insulin resistance, frequent in PCOS patients. On such basis, we investigated the efficacy on insulin sensitivity and hormonal parameters of 8 weeks treatment with myo-inositol (MYO) (Inofert, ItalPharmaco, Milano, Italy) at the dosage of 2 g day in a group (n = 42) of obese PCOS patients,. After the treatment interval body mass index (BMI) and insulin resistance decreased together with luteinizing hormone (LH), LH/FSH and insulin. When subdividing the patients according to their fasting insulin levels, Group A (n = 15) insulin below 12 µU/ml and Group B (n = 27) insulin above 12 µU/ml, MYO treatment induced similar changes in both groups but only patients of Group B showed the significant decrease of both fasting insulin plasma levels (from 20.3 ± 1.8 to 12.9 ± 1.8 µU/ml, p < 0.00001) and of area under the curve (AUC) of insulin under oral glucose tolerance test (OGTT). In conclusion, our study supports the hypothesis that MYO administration is more effective in obese patients with high fasting insulin plasma levels.

Estriol administration modulates luteinizing hormone secretion in women with functional hypothalamic amenorrhea.

OBJECTIVE: To evaluate the influence of estriol administration on the hypothalamus-pituitary function and gonadotropins secretion in patients affected by functional hypothalamic amenorrhea (FHA). DESIGN: Controlled clinical study. SETTING: Patients with FHA in a clinical research environment. PATIENT(S): Twelve hypogonadotropic patients affected by FHA. INTERVENTION(S): Pulsatility study of luteinizing hormone (LH) and follicle-stimulating hormone (FSH), and a gonadotropin-releasing hormone (GnRH) test (10 µg in bolus) at baseline condition and after 8 weeks of therapy with 2 mg/day of estriol. MAIN OUTCOME MEASURE(S): Measurements of plasma LH, FSH, estradiol (E(2)), androstenedione (A), 17α-hydroxyprogesterone (17-OHP), cortisol, androstenedione (A), testosterone (T), thyroid-stimulating hormone (TSH), free triiodothyronine (fT(3)), free thyroxine (fT(4)), and insulin, and pulse detection. RESULT(S): After treatment, the FHA patients showed a statistically significant increase of LH plasma levels (from 0.7 ± 0.1 mIU/mL to 3.5 ± 0.3 mIU/mL) and a statistically significant increase of LH pulse amplitude with no changes in LH pulse frequency. In addition, the LH response to the GnRH bolus was a statistically significant increase. CONCLUSION(S): Estriol administration induced the increase of LH plasma levels in FHA and improved GnRH-induced LH secretion. These findings suggest that estriol administration modulates the neuroendocrine control of the hypothalamus-pituitary unit and induces the recovery of LH synthesis and secretion in hypogonadotropic patients with FHA.

Estimation of instantaneous secretory rates and intrinsic characteristics of luteinizing hormone secretion in women with Kallmann syndrome before and after estriol administration.

Three Kallmann syndrome (KS) patients were examined to assess characteristics of LH response to GnRH bolus, with and without GnRH sensitization using Instantaneous Secretory Rate (ISR) computation before and after estriol treatment (60 days, 2 mg/day). Six healthy women were enrolled as controls and underwent GnRH bolus during the early follicular phase (days 3-5 of the menstrual cycle). After estriol treatment, the KS patients showed a higher LH response to GnRH bolus and similar LH pulse duration to healthy controls. These data support the hypothesis that the administration of weak estrogen improves LH response to GnRH in hypogonadotropic women with KS.

Metformin administration restores allopregnanolone response to adrenocorticotropic hormone (ACTH) stimulation in overweight hyperinsulinemic patients with PCOS.

OBJECTIVE: To investigate the adrenal response in terms of allopregnanolone secretion in a group of hyperinsulinemic patients with polycystic ovary syndrome (PCOS). DESIGN: Controlled clinical study. SETTING: Patients with PCOS in a clinical research environment. PATIENTS: Twenty-two overweight patients with PCOS with hyperinsulinism were enrolled after informed consent. INTERVENTIONS: All patients underwent hormonal evaluations, oral glucose tolerance test (OGTT) and adrenocorticotropic hormone (ACTH) test before and after 4 months of metformin administration (500 mg p.o. bi-daily). Ultrasound examinations and Ferriman-Gallway score were also performed. Main outcome measures. plasma luteinizing hormone (LH), follicle stimulating hormone (FSH), prolactin (PRL), estradiol, 17-hydroxy-progesterone (17OHP), androstenedione (A), testosterone (T), allopregnanolone, glucose, insulin, C peptide concentrations, body mass index (BMI). RESULTS: Metformin administration reduced significantly LH, A, T, insulin and BMI, while allopregnanolone was significantly increased with no change in progesterone plasma levels. Insulin response to OGTT decreased and allopregnanolone response to ACTH stimulation before while this was restored after the treatment interval. The Ferriman-Gallway score as well as the ovarian volume was significantly decreased after 4 months of metformin therapy. CONCLUSIONS: In overweight patients with PCOS with hyperinsulinism, allopregnanolone secretion is impaired and metformin administration restored normal allopregnanolone concentrations modulating both steroid syntheses from the ovaries and from adrenal gland.

Effect of a 2-month treatment with Klamin, a Klamath algae extract, on the general well-being, antioxidant profile and oxidative status of postmenopausal women.

BACKGROUND AND AIM: Because of a growing demand for alternative treatments of the psychological and somatic/vasomotor symptoms related to menopausal transition, in this study we aimed to investigate the effect of a 2-month supplementation period with the Klamath algae extract (Klamin, Nutratec Srl, Urbino, Italy) on the general and psychological well-being of a group of 21 menopausal women not treated with hormonal therapy, as well as on their oxidative stress status and level of antioxidants. Klamin is an extract naturally rich in powerful algal antioxidant molecules (AFA-phycocyanins) and concentrated with Klamath algae's natural neuromodulators (phenylethylamine as well as natural selective MAO-B inhibitors). CONCLUSIONS: At the end of the Klamin supplementation period, plasma lipid peroxidation significantly decreased (as proven by a significant lowering of plasma MDA levels), while the overall antioxidant system improved thanks to the significant increase in the plasma levels of carotenoids, tocopherols and retinol. Furthermore, the average Green Scale score, which evaluates menopausal symptoms and thus by contrast the overall and psychological well-being of menopausal women, was significantly reduced. As it did not show the steroid-like effects on the hormonal parameters, Klamin could be proposed both as a valid natural remedy for women seeking an alternative to hormonal therapy, as well as as a complementary treatment for many climacteric symptoms.
