In 1993, WHO announced a “birth-control vaccine” for “family planning”. Published research shows that by 1976 WHO researchers had conjugated tetanus toxoid (TT) with human chorionic gonadotropin (hCG) producing a “birth-control” vaccine. Conjugatin
Recent studies have demonstrated that MMP1 expression in granulosa cells (GCs) and MMP1 levels in follicular fluid increase when human chorionic gonadotropin (hCG) is administered or by other ovulatory stimuli [12], [16], [17]. These results indicate that MMP1 may play a functional role in ...

To collect ovulated oocytes, female mice received an injection of 10 IU human chorionic gonadotropin (hCG) 48 h after PMSG priming. Oocytes were recovered from oviductal ampullae 13.5 h after hCG, and cumulus cells were removed by a brief incubation in 1 mg/ml hyaluronidase. Histological ...
This study evaluated β-human chorionic gonadotropin (hCG) changes during the early period of pregnancy in an attempt to predict successful pregnancy outcomes in ART. It determined the median values of the β-hCG and the 2-day β-hCG increments of clinical vs biochemical pregnancies. The results...

Human luteinizing hormone (LH) and chorionic gonadotropin (hCG) have been considered biologically equivalent because of their structural similarities and their binding to the same receptor; the LH/CGR. However, accumulating evidence suggest that LH/CGR differentially responds to the two hormones triggerin...
Endoplasmic reticulum (ER) stress generally occurs in secretory cell types. It has been reported that Leydig cells, which produce testosterone in response to human chorionic gonadotropin (hCG), express key steroidogenic enzymes for the regulation of test
The administration of hCG to induce ovulation after ovarian stimulation, or endogenous hCG in conceived pregnancies, is involved in the development of OHSS 4, 5. In conjunction with rapidly increasing E2 levels, hCG may trigger OHSS in predisposed women. As a consequence of this, there is a ...
