There were twenty patients in group A (with GnRH anta...

Antibodies directed against human follicle-stimulating hormone (FSH) were demonstrated in rabbit serum by neutralization of biological activity. Antibodies that bound FSH-(131)I were produced in rabbits and guinea pigs by repeated injections of FSH. By (131)I immunochemical methods, we found that at least 90% of the FSH-(131)I-binding antibody failed to distinguish the four human glycoprotein h...

The role of RNA synthesis was investigated in the action of chorionic gonadotropin on ovaries of immature rats. Chorionic gonadotropin accelerates the ovarian incorporation of [3H]uridine in uivo into rapidly labeled nuclear RNA within 10 min after hormone injection. Analysis of the RNA base composition, expressed as base ratio (A + U):(G + C), shows that hormonal stimulation of the rate of [3H...

The aim of this study was to investigate 2 quantification criteria to evaluate the developmental condition of follicles cohort and clarify their impacts upon the determining of human chorionic gonadotropin trigger timing and the reproductive outcome: the proportion of mature follicles in growing follicles cohort on the day of human chorionic gonadotropin trigger and the peak estradiol level per...
