In this paper, a retrospective cohort study was conducted to the high ovarian responders in GnRH-antagonist protocols of IVF/ICSI cycles. The purpose of the study is to investigate whether dual triggering of final oocyte maturation with a combination of gonadotropin-releasing hormone (GnRH) agonist and human chorionic gonadotropin (HCG) can improve the clinical outcome compared with traditional...

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...

introduction: considering the high incidence of preterm labor and its known complications, and that human myometrium contains receptors for human chronic gonadotropin (hcg) and that hcg can inhibit myometrial contractions on vitro, made me study treating effects of hcg on preterm labor. this clinical trial study was carried out to compare the effect of hcg, and magnesium sulfate (mgso4) on prev...

Testicular germ cell tumors (TGCTs) represent the most common type of solid tumors among men aged 15 to 40 years. An increasing incidence has been recorded in developed countries. In clinical practice, TGCTs are classified as seminomas and non-seminomatous tumors. Non-seminomatous tumors often contain multiple different cell types and can be further sub-divided according to the histological and...

Serial injections (i.m.) of 10 mg follicle stimulating hormone (FSFI-P) to cheetahs for 5 days followed by human chorionic gonadotropin (hCG, 500 IU) administered on both Days 6 and 7 resulted in ovarian follicle development and/or ovulation in six of seven attempts. One additional female given the same gonadotropin regimen when distinct corpora lutea (CL) were visible on the ovaries failed to ...
