The carbohydrate structure of the O-glycosidicallylinked oligosaccharide chains in P-subunit of human chorionic gonadotropin (hCG$) and their precise number and locations in the polypeptide chains have been determined. A homogeneous preparation of the O-glycosidic oligosaccharide was obtained from NaOH/ NaBH,-treated human chorionic gonadotropin by chromatography on Dowex 50 and Sephadex G-25 a...

A 22 years old lady was admitted because of progressive dyspnea, severe abdominal protrusion and lower extremity edema. She had undergone ovarian hyperstimulation for primary infertility by Clomiphen and Human chorionic gonadotropin for 3 months. Abdominopelvic ultrasonography revealed bilateral enlarged multi cystic ovaries and massive ascites. Transesophageal echocardiography revealed a large...

A case-control study was carried out on mothers of boys with undescended testis to investigate the hypotheses that raised maternal levels of oestrogen or reduced levels of human chorionic gonadotrophin in early pregnancy might be factors in the environment of the fetus associated with this condition. No significant difference in the levels of either of these hormones was found, though, if anyth...
