Human chorionic gonadotropin is a glycoprotein composed of 237 amino acids with a molecular mass of 36.7 kDa, approximately 14.5kDa αhCG and 22.2kDa βhCG. [4]It is heterodimeric, with an α (alpha) subunit identical to that of luteinizing hormone (LH), follicle-stimulating hormone (FSH), thyroid-stimulating hormone (TSH), and a β (beta) subunit that is unique to hCG.
Using low dose human chorionic gonadotropin (hCG) to replace FSH during the late follicular phase in women undergoing hyperstimulation as part of IVF may make little or no difference to pregnancy rates, and possibly leads to in an equivalent number of oocytes retrieved, but with less expenditure of FSH.

Human chorionic gonadotropin (hCG), also known as the “hormone of pregnancy” is a hormone that is normally produced during pregnancy and plays an integral role throughout reproduction. [16] It is crucial in maintaining pregnancy, from the stages of placentation to early embryo development. [16]
Gonadotropin therapy refers to the administration of exogenous gonadotropins to treat anovulation. [6] Gonadotropin therapy is given via intrauterine insemination (IUI) and in vitro fertilization (IVF) to exert its effects. [7] FSH promotes the recruitment and maturation of early antral follicles, while LH helps follicular development and ...
It takes, on average, four to six weeks to complete a cycle of GIFT. First, the woman must take a fertility drug to stimulate egg production in the ovaries.The doctor will monitor the growth of the ovarian follicles, and once they are mature, the woman will be injected with human chorionic gonadotropin (hCG).
It’s worth noting that testosterone is just one of several hormones that support male fertility. ... Another alternative to TRT is human chorionic gonadotropin (hCG), which functions like LH by ...
Meet the experts: Jaime Knopman, MD, is a reproductive endocrinologist and director of Fertility Preservation at CCRM Fertility. ... (pregnancy tests look for human chorionic gonadotropin, a ...
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 ...
