Human chorionic gonadotrophin luteal support overcomes luteal phase inadequacy after gonadotrophin-releasing hormone agonist-induced ovulation in gonadotrophin-stimulated cycles.
Gonadotrophin-releasing hormone agonist (GnRHa)-induced ovulation after gonadotrophin ovarian stimulation is used to prevent ovarian hyperstimulation syndrome and multiple pregnancy in polyfollicular cycles. However, one of the major problems to be resolved is corpus luteum function after follicular maturation and ovulation by mid-cycle GnRHa administration. The present report investigated the ...
متن کاملUrinary chorionic gonadotrophin determination.
Successful laboratory tests for early pregnancy utilize the endogenous production and excretion of chorionic gonadotrophin (CG). There is wide variation in sensitivity and specificity of various biological and commercially available immunochemical methods for determining urinary CC levels. Normal values for immunochemically reactive CC during the first trimester of pregnancy are given. Serial d...
متن کاملEffect of gonadotrophin-releasing hormone aned human chorionic gonadotrophin on the response of the ewe to pregnant mare serum gonadotrophin.
An experiment was conducted to determine whether gonadotrophin-releasing hormone (Gn-RH) or HCG would reduce the proportion of unruptured follicles in the Galway ewe following a high superovulating dose of PMSG given in conjunction with a progestagen to synchronize oestrus. Forty-four Galway ewes aged 1\m=1/2\to 5 years (average wt 64\m=.\7kg) were treated with intravaginal pessaries impregnate...
متن کاملHuman chorionic gonadotrophin as an indicator of persistent ges-tational trophoblastic neoplasia
Background : Gestational trophoblastic neoplasia (GTN) disease is excessive and inappropriate proliferation of trophoblast after termination of the pregnancy. Many attempts have been made to improve follow-up procedures, but no studies have evaluated Human Chorionic Gonadotrophin (HCG) as a post treatment indicator. Thus we aimed to know β-HCG variability in post treatment pregnancies. Meth...
متن کاملHuman chorionic gonadotrophin: comparative studies of ovarian uptake in mammals.
-l. The localization of radiolabeled human chorionic gonadotrophin (~2SI-HCG) was studied in a number of commonly used mammalian animal models. 2. The ovary proved to be the target organ for ~25I-HCG in all animals studied. 3. The optimum time for the localization of HCG in the ovary varied in all the mammals extending from 1.5 to 4 hr. 4. HCG is apparently used in the target cell for only a br...
