Background Endometriosis is a chronic, estrogen-dependent condition that causes dysmenorrhea and pelvic pain. Elagolix, an oral, nonpeptide, gonadotropin-releasing hormone (GnRH) antagonist, produced partial to nearly full estrogen suppression in previous studies. Methods We performed two similar, double-blind, randomized, 6-month phase 3 trials (Elaris Endometriosis I and II [EM-I and EM-II]) to evaluate the effects of two doses of elagolix - 150 mg once daily (lower-dose group) and 200 mg twice daily (higher-dose group) - as compared with placebo in women with surgically diagnosed endometriosis and moderate or severe endometriosis-associated pain...

Tubal pathology, smoking, pelvic inflammatory disease, miscarriage, medical or surgical abortion, usage of intrauterine devices (IUDs) for women with salpingitis latent injuries, older than 40 years, are risk factors for ectopic pregnancy. The objective of this study concerns the correlation of the clinical and biological evidence for the early diagnosis of the ectopic pregnancy and, as soon as possible, for the estimation for eventual risk of complications that may appear. The transvaginal ultrasound test, minimal increases in serum beta-human chorionic gonadotropin (β-hCG) dynamics and blood counts are investigations of choice in achieving our objective...

The kisspeptin is a neuropeptide to play physiological roles in regulating gonadotropin-releasing hormone secretion in the hypothalamus. In human plasma, the kisspeptin concentration is measured, but gonadotropin-releasing hormone is not. This study aims to understand the physiological roles of the circulating kisspeptin in lactational amenorrhea in humans because prolactin reduces the kisspeptin expression and luteinizing hormone secretion resulting in anovulations in rodent brains. Plasma kisspeptin levels were measured in 11 subjects in lactational amenorrhea and in four cases with pathological amenorrhea by different etiologies for comparison using the enzyme immunoassay specific for human kisspeptin...

BACKGROUND: Gonadotropin-releasing hormone (GnRH) antagonist protocol has been proposed as a potentially proper option for the patients with limited ovarian reserve. Nevertheless, there is no significant difference in terms of clinical pregnancy between the GnRH antagonist and agonist cycles. The use of aromatase inhibitors such as letrozole was suggested by some studies. OBJECTIVE: The object of this study was to evaluate the efficacy of letrozole co-treatment with GnRH-antagonist protocol in ovarian stimulation of poor responder patients undergoing intracytoplasmic sperm injection...

SUMMARY: Primary amenorrhoea is defined as the failure to commence menstruation by the age of 15 years, in the presence of normal secondary sexual development. The potential causes of primary amenorrhoea extend from structural to chromosomal abnormalities. Polycystic ovarian syndrome (PCOS) is a common cause of secondary amenorrhoea but an uncommon cause of primary amenorrhoea. An early and prompt diagnosis of PCOS is important, as up to 30% of these women are predisposed to glucose intolerance and obesity, with the subgroup of women presenting with primary amenorrhoea and PCOS displaying a higher incidence of metabolic dysfunction...

Our objective was to evaluate the safety and efficacy of direct initiation of gonadotropin ovarian stimulation without prior withdrawal bleeding in anovulatory clomiphene citrate (CC) resistant polycystic ovarian syndrome (PCOS) patients. Eighteen PCOS patients underwent ovulation induction with CC using a stair-step regimen. Patients who failed to respond to the maximal dose of CC initiated gonadotropin stimulation without inducing withdrawal bleeding, using the chronic low dose regimen. The primary outcome measure was the time to ovulation from the beginning of CC treatment until the day of ovulatory trigger...
