Clauberg S. (Zentrbl. F. Gyn., 1933, No. 1, p. 47), based on the presence of luteinizing hormone in blood pregnant women anterior lobe pituitary gland, recommends cases uterine bleeding, depending persistence follicles ovary with insufficient development corpus luteum, pour over bleeding about 300-400 cc, sant.

Effective contraception is necessary in countries where limiting population growth has become a public policy imperative. The main antigenic targets for contraceptive vaccine development can be listed as following: 1) sperm antigens, 2) zona pellucida antigens, 3) gonadotrophin-releasing hormone, 4) chorionic gonadotrophin, 5) other protein/peptide hormones (follicle-stimulating hormone, lutein...

We compared five two-site immunometric assays (including three commercially available kits) for measuring lutropin (LH) in serum. Four of the assays involved monoclonal antibodies directed against the alpha-beta dimer, intact LH; these assays measured significantly lower concentrations of LH in 19 (out of 83) samples than did a commercial method not involving such antibodies. In five serum samp...

Discrepancies among three commercially available luteinising hormone (LH) radioimmunoassay RIA kits, all calibrated against the second-IRP-HMG (World Health Organisation International Laboratory for Biological Standards), were observed. Even though the Japan Radioisotope Association carries out external quality control in Japan every year, inaccuracies still exist. This problem also exists else...

Gonadotropin-releasing hormone in Cyprinidae as in other Vertebrates functions as a brain signal which stimulates the secretion of luteinizing hormone from the pituitary gland. Two forms of gonadotropin-releasing hormone have been identified in cyprinids, chicken gonadotropin-releasing hormone II and salmon gonadotropinreleasing hormone. Hypohysiotropic functions are fulfilled mainly by salmon ...

OBJECTIVES To investigate factors associated with the response to ovarian stimulation in patients with polycystic ovary syndrome. Methods: The records of patients with polycystic ovary syndrome and infertility who underwent ovulation induction with clomiphene citrate were reviwed between January 2011 and December 2014 in Etlik Zübeyde Hanim Women's Health Training and Research Hospital Ankara, ...

Spermatogenesis is thought to critically depend on the high intratesticular testosterone (T) levels induced by gonadotropic hormones. Strategies for hormonal male contraception are based on disruption of this regulatory mechanism through blockage of gonadotropin secretion. Although exogenous T or T plus progestin treatments efficiently block gonadotropin secretion and suppress testicular T prod...
