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 .
The application of utilizing eFSH to increase the efficiency of equine embryo transfer was tested at the University of Saskatchewan.Embryos from 12 donor mares at 8 days of ovulation were recovered, scored, then transferred to 37 recipients mares who were tested for pregnancy after 7-10 days. 5 pregnancies resulted from the 15 embryos were recovered from the eFSA treatment group and 4 ...
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 ...
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 ...
The frog test had been a highly dependable pregnancy testing method since the 1930s until the immunological test was presented in the 1960s. [12] Pharmacists would inject the female's early urine sample into the frogs and confirm their pregnancy with the spawning of eggs within 18 hours. However, there was a critical prerequisite for accurately ...
[1] [7] The estrogens in CEEs, in their unconjugated active forms, include bioidentical human estrogens like estradiol and estrone as well as equine-specific estrogens such as equilin and 17β-dihydroequilin. [1] [7] The equine estrogens differ from human estrogens in that they have additional double bonds in the B ring of the steroid nucleus.

Pituitary pars intermedia dysfunction (PPID), or equine Cushing's disease, is an endocrine disease affecting the pituitary gland of horses. It is most commonly seen in older animals, [ 1 ] and is classically associated with the formation of a long, wavy coat ( hirsutism ) and chronic laminitis .
