background: our objective was to evaluate the effectiveness of clomiphene citrate (cc) vs. letrozole (l) plus human menopausal gonadotropin (hmg) in gonadotropin releasing hormone (gnrh) antagonist protocol in poor prognosis women with previous failed ovarian stimulation undergoing intracytoplasmic sperm injection (icsi). materials and methods: this retrospective cohort study included cycles wi...

history and objectives: considering the incremental trend for using the stimulatory drugs for ovulation and the new techniques for the treatment of infertility, therefore there is a higher incidence for the syndrome of polycystic ovaries. in this research study mannitol serum was used as a preventive agent in patients with such a syndrome referred to sarem medical center from 1999 to 2000. mate...

Early pregnancy bleeding is a common presentation in the emergency setting. Traditionally, its assessment relied on clinical findings, including pelvic examination. However in recent years, ultrasonography and quantitative beta human chorionic gonadotropin assays have gained prominence and are now first-line in diagnosing early pregnancy bleeding. Accordingly, the role of pelvic examination in ...

By using human menopausal gonadotropin (HMG) and human chorionic gonadotropin (HCG), fairly good clinical therapeutic efficacy has been obtained in the treatment of infertility. However, difficulties are brought about due to the ovarian hyperstimulation syndrome (OHSS) easily induced by these two drugs. Therefore, we attempted to use acupuncture instead of HCG in the induction of ovulation from...

Stanniocalcin (STC) in fish maintains calcium and phosphate homeostasis, whereas mammalian STC1 shows a diverse tissue expression pattern with ovary exhibiting the highest level. Based on the known expression of STC1 in theca/interstitial cells of the ovary, we generated recombinant N-glycosylated STC1 protein and tested its ability to modulate granulosa cell differentiation. In cultured rat gr...
