OBJECTIVES: To present a single-center experience with testicular sperm extraction and intracytoplasmic sperm injection for fathering biological children in patients with ejaculatory dysfunction as a result of spinal cord injury. METHODS: Testicular sperm extraction was carried out in 52 male patients with ejaculatory dysfunction as a result of spinal cord injury. We investigated sperm retrieval rates and pregnancy rates from medical records. Data on age, testicular volume, hormonal status (luteinizing hormone, follicle stimulating hormone and testosterone), and time since spinal cord injury were obtained and analyzed to detect potential associations with the presence of spermatogenesis...

PURPOSE: Degarelix, a new GnRH receptor antagonist with demonstrated efficacy as first-line treatment in the management of high-risk prostate cancer, possesses some theoretical advantages over LHRH analogues in terms of avoiding "testosterone flare" and lower FSH levels. We set out to determine if pre-operative degarelix influenced surrogates of disease control in a randomized phase II study. EXPERIMENTAL DESIGN: 39 patients were randomly assigned to one of 3 different neo-adjuvant arms: degarelix only, degarelix/bicalutmaide, or LHRH agonist/bicalutamide...

Effect of a GnRH-agonist (deslorelin) was studied on reproductive function and ovarian luteinizing hormone receptor (LHR) and follicle stimulating hormone receptor (FSHR) expression in prepubertal female cats that were either implanted with 4.7-mg deslorelin (implanted: n = 6) or not (controls: n = 18) or ovariohysterectomized at prepubertal age (prepubertal OVH: n = 6). Body weights, fecal estradiol, and sexual behavior of implanted and control cats were monitored for 48 weeks followed by collection of ovaries and uteri...

Objective: To compare serum anti-Müllerian hormone (AMH) and other endocrine parameters between patients diagnosed with polycystic ovary syndrome (PCOS) and age-matched ovulatory women. Materials and methods: AMH, DHEAS, FSH, LH, PRL, TSH and total testosterone (TT) were prospectively measured in oligo-ovulatory PCOS patients (n = 595) and in ovulatory non-PCOS women (n = 157) referred to a tertiary infertility center. Mean BMI was similar across the two study populations and there were no smokers in the sample...

Adipose tissue plays an important role in regulating female fertility owing to not only its energy stores but also the endocrine actions of secreted adipokines. As one of the adipokines, adiponectin is almost exclusively secreted from the fat and its circulating concentration is paradoxically reduced in obesity. Although recent studies implied a purported positive role of adiponectin in ovarian functions, definitive in vivo evidence has been sorely lacking. We have consistently observed subfertility in female adiponectin null mice, and therefore postulated a protective role of adiponectin in ovarian functions...

Breeding bulls are commonly fed high-energy diets, which may induce subacute ruminal acidosis (SARA). In this experiment, 8 Santa Gertrudis bulls (age 20 ± 6 mo) were used to evaluate the extent and duration of effects of SARA on semen quality and the associated changes in circulating hormones and metabolites. The bulls were relocated and fed in yards with unrestricted access to hay and daily individual concentrate feeding for 125 d before SARA challenge. Semen was collected and assessed at 14-d intervals before the challenge to ensure acclimatization and the attainment of a stable spermiogram...

The aim of this retrospective cohort study was to assess differences in infertility-related baseline characteristics and IVF outcome between European and Middle Eastern/North African (MENA) patients. Of 2703 patients undergoing their first IVF cycle, 2485 were Caucasian of European descent and 218 originated from the MENA region. MENA patients were significantly younger (30.6 versus 34.0 years, P < 0.001), less likely smokers, with higher body mass indexes. Infertility duration was longer in MENA patients (P < 0...

PURPOSE: This study aimed to test the hypothesis that erectile dysfunction (ED) is common in men with obstructive sleep apnea (OSA). We also assessed the efficacy of continuous positive airway pressure (CPAP) treatment for ED and sex hormone levels in patients with severe OSA and ED. METHODS: A total of 153 OSA patients and 60 healthy controls were enrolled in this study. The International Index of Erectile Dysfunction-5 (IIEF-5) score was obtained, and blood samples were collected for analysis of sex hormones after polysomnography...

PURPOSE: Menopause is frequently associated with an increase in visceral fat, thus modifying redox status by promoting oxidative damage and decreasing antioxidant defense systems. It is known that at higher concentrations estradiol has some antioxidant properties, while its decline in postmenopause is associated with pro-oxidant effects. However, the role of follicle stimulating hormone (FSH) in antioxidant defense in postmenopausal women is still not well elucidated. Therefore, we aimed to evaluate the potential complex association between visceral obesity, FSH and enzymatic antioxidant defense as measured by glutathione peroxidase (GPx) in postmenopausal women...

Whilst disturbances of female reproductive hormones and function are commonplace in opioid dependence, their pathophysiological interrelationships are not well understood. Hormonal levels in females were compared in 77 opioid dependent patients (ODP) and 148 medical controls (MC) including 205 and 364 repeat studies. Significant changes in FSH, LH, oestradiol, testosterone and SBG were noted including power functions with age. The FSH/LH was lower in ODP (P=0.0150) and the ratio inversion point occurred at 28...

OBJECTIVE: To evaluate the efficacy and safety of Heyan Kuntai Capsule (, HYKT) and hormone therapy (HT) on perimenopausal syndromes (PMSs). METHODS: From 2005 to 2008, 390 women with PMSs were recruited from 4 clinic centers. The inclusion criteria included ages 40 to 60 years, estradiol (E2) below 30 ng/L, and follicle stimulating hormone (FSH) above 40 IU/L, etc. The patients were randomly assigned to HYKT group or HT group by random number table method, administrated HYKT or conjugated estrogen with/without medroxyprogesterone acetate tablets for 12 months...

CONTEXT: Kisspeptin and neurokinin B (NKB) are obligate for normal gonadotropin secretion, but their hierarchy is unexplored in normal women. OBJECTIVE: To investigate the interaction between kisspeptin and NKB on estrogen-regulated LH secretion. DESIGN: Women were treated with NK3R antagonist followed by transdermal estradiol to induce LH secretion 48hr later, with kisspeptin-10 or vehicle infusion during estrogen administration in a two-way cross-over study...

Polycystic ovarian syndrome (PCOS) is one of the pathological factors involved in the failure of in vitro fertilization (IvF). The aim of the present study was to investigate if the combination of myoinositol + folic acid was able to improve the oocyte quality, the ratio between follicles and retrieved oocytes, the fertilization rate, and the embryo quality in PCOS patients undergoing IvF treatments. 29 patients with PCOS underwent IvF protocols for infertility treatment and were randomized prospectively into two groups...

STUDY QUESTION: Does hormonal stimulation with corifollitropin alpha (CFA) only, mimicking a step down protocol, result in lower incidence of progesterone elevation on the day of hCGtrigger as compared to sustained stimulation with recombinant FSH (rFSH)? SUMMARY ANSWER: The current findings support the concept that sustained FSH stimulus contributes to premature progesterone elevation in stimulated IVF cycles. WHAT IS KNOWN ALREADY: Serum progesterone rise during the follicular phase of ovarian stimulation for IVF treatment seems to be related to a poorer reproductive outcome...

PURPOSE: Premature ejaculation is considered the most common type of male sexual dysfunction. Hormonal controls of ejaculation have not been exactly elucidated. The aim of our study is to investigate the role of hormonal factors in patients with premature ejaculation. MATERIALS AND METHODS: Sixty-three participants who consulted our outpatient clinics with complaints of premature ejaculation and 39 healthy men as a control group selected from volunteers were included in the study...

In the domestic cat, the efficiency of in vitro embryo production systems is negatively affected during the nonbreeding season. The objective of this research was to evaluate the effect of FSH stimulation in anestrous cats, on quality of cumulus-oocyte complexes (COCs) and in vitro developmental competence after parthenogenetic activation. To accomplish this purpose, anestrous cats were grouped into: (1) FSH treated (serial doses of 5 mg of porcine FSH each, every 24 hours, for 4 days) and (2) untreated control...
