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 ...
Before immunological pregnancy tests were developed in the 1960s, women relied on urine-based pregnancy tests using animals, ranging from mice to frogs. [1] [2] Advancements in medical technology have enabled women to accurately check their pregnancy status by using 'pee-on-a-stick' pregnancy test kits at home. Before these accessible and ...
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 ...
Oral CEEs 1.25 mg/daily and oral micronized estradiol 1 mg/daily result in similar plasma concentrations of estrone and estradiol (150–300 pg/mL and 30–50 pg/mL for micronized estradiol, respectively) (oral estradiol is extensively metabolized into estrone during hepatic first-pass metabolism), [72] although this does not account for ...
During pregnancy, the syncytiotrophoblast cells of the placenta produce a polypeptide hormone, human placental lactogen (hPL), also known as human chorionic somatomammotropin (hCS). [ 17 ] in six weeks of gestation , production of hPL in maternal plasma is detected, then the concentration of hPL keeps increasing until week 30 of pregnancy. [ 17 ]
In mammals, pregnancy is the period of reproduction during which a female carries one or more live offspring from implantation in the uterus through gestation. It begins when a fertilized zygote implants in the female's uterus , and ends once it leaves the uterus.
Breast development throughout pregnancy may result in significant Areola and Areolar gland enlargement, erectile nipples, and/or nipple sensitivity. [8] [9] A woman's breasts grow during pregnancy, typically 1 to 2 cup sizes. [10] A woman who wore a C cup bra prior to her pregnancy may need to buy an F cup or larger bra while nursing. [11]
