Hyperglycosylated human chorionic gonadotropin (H-hCG) is secreted by the placenta in early pregnancy. Decreased H-hCG levels have been associated with abortion in spontaneous pregnancy. We retrospectively measured H-hCG and dimeric hCG in the sera of 87 in vitro fertilization patients obtained in the 3 weeks following embryo transfer and set the results in relation to pregnancy outcome. H-hCG ...

An exogenous gonadotropin regimen and a laparoscopic intrauterine artificial insemination (AI) technique, previously developed in the domestic cat, were adapted and assessed for effectiveness in the cheetah (Acinonyx jubatus). Seven female cheetahs were given an injection of either 200 or 400IU pregnant mares' serum gonadotropin (PMSG) and either 125 or 250IU human chorionic gonadotropin (hCG) ...

Objective: To evaluate and compare cycle outcomes following triggering final oocyte maturation with dual trigger of concomitant gonadotropin-releasing hormone (GnRH) agonist human chorionic gonadotropin (hCG) administration versus hCG alone for women expected normal ovarian response that underwent antagonist cycles intracytoplasmic sperm injection (ICSI). Material Methods: Women GnRH ICSI betwe...

The current study was performed to investigate the effect of oocyte donor status, including age and body weight, on metaphase II (MII) oocyte recovery using two superovulation methods in cynomolgus monkeys. The use of Method A [recombinant gonadotrophin (75 IU/kg, 3 ×, 3-day intervals) and human chorionic gonadotropin (hCG)] led to great increases in ovary size and the mean number of MII oocyte...

This review describes briefly the beneficial use of two vaccines developed by us for treatment of cancers. The vaccine against Luteinizing Hormone Releasing Hormone (LHRH) is effective in carcinoma of prostate as well as in breast cancers dependent on androgens and estrogens respectively. LHRH being identical in both males and females, the same vaccine is usable in both Prostate and Breast ster...

Choriocarcinoma is a curable malignancy that occurred approximately 50% after term pregnancies, and prognosis in this form of gestational trophoblastic Disease (GTD) is Poor. The earliest onset choriocarcinoma after term pregnancy in one study was reported 3 weeks after delivery, but in current study, choriocarcinoma was diagnosed 2 weeks after delivery. 28 years-old women gravidity 2, parity 2...

OBJECTIVES To provide clarity on the use of qualitative and quantitative human chorionic gonadotropin (hCG) tests for the assessment of pregnancy. METHODS A case scenario and a brief review of the relevant literature describing clinical and analytical considerations regarding hCG testing are presented. RESULTS In pregnancy, hCG is nearly always detectable in serum and urine within 16 days a...

Screening examination for maternal, especially serum, is a non-invasive of the fetus’s condition. During pregnancy, screening examinations are performed in women recommended ultrasonography (USG), amniocentesis, or other obstetric interventions. There three markers maternal serum screening: alpha-fetoprotein, human chorionic gonadotropin (hCG), and unconjugated estriol. Maternal alpha-fetoprote...

The effects of passive immunoneutralization of endogenous inhibin on ovulation rate in immature rats were investigated. Efficiency of superovulation on production of fertilized oocytes was compared between the inhibin antiserum (inhibin-AS) and equine chorionic gonadotropin (eCG) protocols. Immature female Wistar strain rats were superovulated with a single injection of 100-200 microl inhibin-A...
