Equine chorionic gonadotropin (acronym given as eCG but not to be confused with ECG) is a gonadotropic hormone produced in the chorion of pregnant mares.Previously referred to as pregnant mare's serum gonadotropin (PMSG), the hormone is commonly used in concert with progestogen to induce ovulation in livestock prior to artificial insemination.
They produce high concentrations of equine chorionic gonadotropin (eCG), also called pregnant mare's serum gonadotropin, in the bloodstream of pregnant mares. eCG is actually an equine luteinizing hormone. [2] Endometrial cups behave somewhat like cells from metastatic tumors, in that they leave the placenta and migrate into the uterus. Their ...
Gonadotropins are glycoprotein hormones secreted by gonadotropic cells of the anterior pituitary of vertebrates. [1] [2] [3] This family includes the mammalian hormones follicle-stimulating hormone (FSH) and luteinizing hormone (LH), the placental/chorionic gonadotropins, human chorionic gonadotropin (hCG) and equine chorionic gonadotropin (eCG), [3] as well as at least two forms of fish ...

If pregnancy occurs in equine, the placental hormone equine chorionic gonadotropin released by endometrial cup acts like LH and FSH and stimulates additional ovulations, although the oocytes released during these ovulations are not fertilized. The resulting accessory corpora lutea produce progesterone and keep levels of progesterone high during ...
This can be achieved by using hormones to manipulate the female's reproductive organs. The hormones used are typically gonadotropin-like, meaning they stimulate the gonads. [28] Follicle stimulating hormone is the preferred hormone in cattle, sheep and goats. While in pigs, equine chorionic gonadotropin is preferred.

The luteinizing hormone beta subunit is encoded by a single gene in all mammals. In primates, this gene is located within a cluster that arose through gene duplication, and also includes multiple redundant genes encoding the beta subunit of chorionic gonadotropin as well as several nonfunctional pseudogenes.
