Hypogonadotropic hypogonadism is defined as a medical condition with low or undetectable gonadotropin secretion, associated with a complete arrest of follicular growth and very low estradiol. The main cause can be traced back to an irregular or absent hypothalamic GnRH secretion, whereas only a minority suffers from a pituitary disorder. The choice of treatment to reverse this situation is a pu...

OBJECTIVE This study aimed to investigate the effect of a new clomiphene citrate (CC) regimen on preventing thin endometrial lining in polycystic ovary syndrome (PCOS) patients receiving CC plus gonadotropin treatment with a timed intercourse cycle. METHODS A total of 114 women with PCOS were included in this trial. Patients were divided into two groups and treated in accordance with the cont...

Ovarian hyperstimulation syndrome (OHSS) is the price patients pay for our attempt to override nature’s delicate balances that were created to assure a single oocyte ovulation. Spontaneous OHSS does occur, as we delineate later. It is, however, very rare. Indeed, natural-cycle-based assisted reproductive technologies (ART) were responsible for the birth of the first IVF baby; however, this meth...

Background The purpose of this prospective randomized study was to compare ovarian response as well as oocytes embryo yields and pregnancy rates in women who underwent ovulation induction for intracytoplasmic sperm injection (ICSI) with recombinant human FSH (rFSH) alone or in combination with human menopausal gonadotropin (HMG). MaterialsAndMethods Out of 300 patients in assisted reproductive ...

Background The safety and tolerability of a new highly purified, urine-derived human menopausal gonadotropin (hMG) preparation [Menopur(R)] was compared with a currently available hMG [Repronex (R)] in women undergoing in vitro fertilization (IVF). Methods This was a randomized, open-label, parallel-group, multicenter study conducted in subjects undergoing IVFTable 1. Overall, subjects in the t...

BACKGROUND We aimed to compare human menopausal gonadotropin (hMG) and recombinant follicle-stimulating hormone (r FSH) with respect to clinical outcomes and the development of ovarian hyperstimulation syndrome (OHSS) for patients with polycystic ovary syndrome (PCOS) treated with in vitro fertilization (IVF). MATERIALS AND METHODS This prospective randomized controlled trial included a total...

background: gonadotropin-releasing hormone agonists or antagonists are used in assisted reproductive technique cycles as premature luteinizing hormone secretion inhibition. studies have been reported different and contradictory results on the serum progesterone effect on intra-cytoplasmic sperm injection. objective: the purpose of this study was to evaluate the effect of serum progesterone leve...

Abstract Study question Which patients are eligible to skip ovulation monitoring before day 10 in In Vitro Fertilization (IVF) and what the financial implications? Summary answer Thanks our innovative gonadotropin prescription algorithm, with low ovarian reserve maximum stimulation may not require until of IVF. What is known already most fertility clinics, standard procedure for IVF early on 6 ...

OBJECTIVE To conduct a systematic overview of available data comparing FSH with hMG in IVF treatment cycles. DESIGN A meta-analysis of randomized trials of FSH versus hMG use in ovarian stimulation protocols, with or without GnRH agonists, in IVF treatment cycles. Search strategies included on-line searching of the National Library of Medicine MEDLINE data base from 1975 to 1993 and hand sear...
