abstract: introduction & objective: the infertility treatment by using in vitro matured oocyte has many potential applications. it minimizes the risk of ovarian hyper stimulation and is an alternative treatment for women with polycystic ovarian syndrome who may have problems regarding stimulation for ivf. this method may prove important for subjects in need of fertility preservation and also pr...

With the increasing use of gonadotropin releasing hormone antagonist protocols, it has become an option to trigger ovulation with gonadotropin releasing hormone agonist which has several advantages over human chorionic gonadotropin triggering; among those an elimination or reduction in ovarian hyperstimulation syndrome, and a reduction in luteal phase discomfort. Thus, this paper questions the ...

Urinary estradiol production rates, plasma estradiol, and peripheral conversion of dehydroepiandrosterone sulfate (DHEAS) to estradiol were explored in patients whose neoplasms made human chorionic gonadotropin and/or human chorionic gonadotropin beta fragments. In five men with choriocarcinoma, estradiol production was elevated, plasma estradiol was high, and DHEAS conversion to estradiol rang...

Plasma membranes isolated from bovine corpora lutea showed specific binding with 1251-human chorionic gonadotropin and 1251-human luteinizing hormone; unlabeled hormones competitively inhibited the binding. The binding of the 1251-human chorionic gonadotropin to the receptor was a saturable phenomenon and the half-saturation was attained at a concentration of 4 X lo-r0 M. Maximum hormone recept...

INTRODUCTION We describe a case of non-small cell lung cancer that was found to stain positive for beta-human chorionic gonadotropin on immunohistochemistry. Only a few case reports have described lung cancers that secrete beta-human chorionic gonadotropin. CASE PRESENTATION A 68-year-old Caucasian man presented with symptoms of weakness, fatigue and weight loss for the past two months. On ex...

background: spontaneous ovarian hyperstimulation syndrome rarely occurs during pregnancy and is usually associated with high levels of human chorionic gonadotropin, in conditions such as molar or multifetal pregnancies. case report: here we report spontaneous ovarian hyperstimulation in a patient presenting with missed abortion at 16th week of gestation, when serum ß-subunit human chorionic gon...

We report the case of a 22-year-old male who had a history of metastatic right testicular tumor successfully treated with chemotherapy and surgery. Twenty-one months after the initial treatment, the serum human chorionic gonadotropin started to increase gradually, but whole body imaging including the left testis revealed no abnormal finding except testicular microlithiasis. A biopsy of the left...
