Study Objectives: Menopausal transition is associated with increased dissatisfaction with sleep, but the effects on sleep architecture are conflicting. This prospective six-year follow-up study was designed to evaluate the changes in sleep stages and sleep continuity that occur in women during menopausal transition. Methods: Sixty women (mean age 46.0 years, SD 0.9) participated. All women were premenopausal at baseline, and at the six-year follow-up, women were in different stages of menopausal transition...

Cycles with progesterone elevation during controlled ovarian stimulation (COS) for IVF/ICSI are commonly managed with a "freeze-all" strategy, due to a well-recognized detrimental effect of high progesterone levels on endometrial receptivity. However, also a detrimental effect of elevated progesterone on day-3 embryo quality has recently been found with regards to top quality embryo formation rate. Because blastocyst culture and cryopreservation are largely adopted, we deemed relevant to determine whether this detrimental effect is also seen on blastocyst quality on day 5-6...

This study was designed to investigate the relationships between indicators of male body-mass index (BMI), age, reproductive hormone levels, semen parameters and the outcomes of assisted reproductive technology (ART). The clinical data were collected from 636 couples who underwent ART at the reproductive center involved in our study. Pearson's correlation or Spearman rank correlation was applied to establish the relevant correlation coefficients. The correlation between influence factors' and pregnancy outcomes was analyzed using the Logistic regression model...

Recombinant DNA technologies have produced Corifollitropin alfa (CFa) used during IVF/ICSI in order to keep the circulating FSH levels above the threshold necessary to support multi-follicular growth for a week. In this prospective case-control study, we compared 70 participants treated with 150 μg CFa combined with 150 IU of follitropin beta (study group) with 70 subfertile participants with matching baseline characteristics, conforming with the same inclusion criteria and treated with an antagonist protocol using follitropin beta (control group)...

Prenatal betamethasone (BM) exposure in rats negatively impacts sperm quality and male fertility. Studies have shown that BM can cause multi-generational effects on the pituitary-adrenal-axis of rats. The objective of this study was to assess the reproductive development and fertility of male rats (F2) whose fathers (F1) were exposed to BM (0.1mg/kg) on gestational days 12, 13, 18 and 19. In F2 rats, there was a significant reduction in body weights of the BM-treated group at PND 1 as well as delayed onset of puberty, and decreases in FSH levels, Leydig cell volume, sperm number and motility, seminal vesicle contractility and ejaculated volume...

REVIEW
Ying Guo, Junyan Sun, Dongmei Lai
Premature ovarian insufficiency (POI) is a typical disorder of amenorrhea lasting for a minimum of 4 months. The typical characteristics comprised of declined estrogen and raised serum concentrations of follicle-stimulating hormone (FSH) in women <40-year-old, primarily originating from iatrogenic factors, karyotypic abnormalities, and genetic factors. However, the etiology of POI remains unknown in approximately 90% of cases. POI could lead to infertility, osteoporosis, cardiovascular disorder, and cognitive dysfunction...

BACKGROUND: Nicotine (Nic) is a major risk factor in the development of functional disorders of male reproductive system. Achillea millefolium; is highly regarded for medicinal activities, due to its antioxidant and anti-inflammatory properties. This study was carried out to evaluate whether Achillea millefolium (Achm) inflorescences alcoholic extract could serve as a protective agent in male reproductive male failures during Nic exposure in a rat model. METHODS: Twenty-five adult male Wistar rats were categorized into the five groups...

BACKGROUND: We aimed to test the hypothesis that the correlation of the changes in the blood Androstenedione (A4) levels to the number of selected follicles during ovulation induction with low-dose recombinant human follicle stimulating hormone (rhFSH) is as strong as the correlation to changes in the blood Estradiol (E2) levels in polycystic ovary syndrome (PCOS). METHODS: Prospective Case-control study conducted from October 2014 to January 2016. 61 non-PCOS control (Group I) and 46 PCOS (Group II) patients treated with the chronic low-dose step up protocosl with rhFSH...

The study was conducted to optimize lighting schedule for pre-pubertal (12 to 22 weeks) Chinese native breed Pengxian yellow pullet. A total of 414 healthy pullets (10 weeks), with similar body weight were randomly distributed into three groups (n = 138) and housed in individual cages for up to 12 weeks of age in light controlled rooms and provided normal lighting schedule (10L:14D). At 12 to 18 weeks of age, pullets were housed in three rooms, having varying lighting schedule viz. G1 (8L: 16D), G2 (10L:14D), or G3 (12L:12D)...

In order to achieve successful captive breeding the Podocnemis expansa, it is necessary to study their reproductive endocrinology. The purpose of this research was to evaluate and characterize plasma concentrations in gonadotrophic, gonadic, corticosterone and prolactin hormones from Giant Amazon Turtles under captive conditions. Blood samples were collected over a 15 month period. The samples were assayed by the use of radioimmunoassay, prolactin, corticosterone, LH, FSH, testosterone, 17β-estradiol and progesterone...

The principal aim of this retrospective study was to examine the relationship between sperm apoptotic biomarkers and the patient's biclinical characteristics, the conventional sperm parameters and the results of assisted reproductive technology. Sperm analysis, activated caspases, annexin V staining for phosphatidylserine (PS) externalisation and labelling assay for DNA fragmentation were assessed in 122 males of infertile couples. Fifty-seven couples were allocated to the natural conception group, and 65 couples underwent IVF or ICSI...

BACKGROUND: In previous reports no differences in Leydig and Sertoli cell function were found between congenital undescended testis (CUDT) and acquired UDT (AUDT) on the basis of serum levels of LH, testosterone, FSH or inhibin B. This study tried to detect differences in Leydig and Sertoli cell function between CUDT and AUDT using insulin-like peptide 3 (INSL3) and anti-Müllerian hormone (AMH). METHOD: 118 men with a history of UDT (CUDT N=55 (6/55 bilateral), AUDT N=63 (15/63 bilateral)) were investigated...

OBJECTIVE: In this paper, we focused on the toxic effect of ketamine on the reproductive system in male rats and its underlying mechanisms. MATERIALS AND METHODS: Rats were randomly allocated into four groups (n=10), i.e. a control group and 3 ketamine groups (high-dose, mid-dose, low-dose). Animals in the ketamine groups received an intraperitoneal injection of ketamine (20, 40 or 60 mg/kg) every 3 days for 7 times. Control rats were injected with normal saline instead...

BACKGROUND: There is significant evidence among the general population regarding the impact of physical activity in improving the quality of life; however, evidence regarding the effect of physical activity in improving fertility and the quality of life in infertile women is inadequate. Existing medical literature shows that moderately regular physical activity positively influences ovarian reserve and assisted reproductive technology (ART) outcomes in overweight and obese women. It is not known whether moderate physical activity influences ovarian reserve in normal weight reproductive age women, and whether age has any influence on the physical activity related changes in ovarian reserve...

Although an acceleration of male pubertal development has been observed, precisely which endocrine-disrupting chemicals (EDCs) might contribute to the advancing onset of puberty in boys remains unclear. Here, pyrethroids, a class of widely used insecticides that have been as considered as EDCs, are proposed as new environmental risk factors. In this study, 463 boys at the age of 9-16 years old were recruited in Hangzhou, Zhejiang, China. The common metabolites of pyrethroids, 3-phenoxybenzoic acid (3-PBA) and 4-fluro-3-phenoxybenzoic acid (4-F-3-PBA), as well as the gonadotropins, including luteinizing hormone (LH) and follicle-stimulating hormone (FSH), were analyzed in urine samples...
