INTRODUCTION This study was undertaken to compare between clomiphene citrate (CC) and gonadotropin-releasing hormone antagonist-based protocols in donor-recipient cycles in terms of parameters of ovarian stimulation and obstetric outcome. MATERIALS AND METHODS Two hundred and three fertile oocyte donors were stimulated using two different protocols: Clomiphene based (n = 103) and antagonist b...

The induction of ovulation by clomiphene could be the result of interaction of the drug at various levels: hypothalamus, pituitary and ovary. It was demonstrated that administration of clomiphene to women with polycystic ovarian syndrome (PCOS) is accompanied by a reduction in plasma concentrations of insulin-like growth factor-I (IGF-I). IGF-I seems to have an overall negative effect on normal...

Spermatogenesis is a fascinating biological process aiming to generate haploid spermatozoa from diploid spermatogonia through a specific hormonal network between gonadotropins and steroids. Increasing evidence suggests that the primary female sex hormone estrogen plays an active role in this process. This research points out on the role of estrogen during lizard spermatogenesis by using three e...
