Control of Ovulation with Human Gonadotrophins

摘要: It is through the two gonadotropins, follicle stimulating hormone (FSH) and luteinizing (LH), that anterior pituitary controls timing of ovulation number follicles rupture. Under influence FSH, follicular growth occurs at a constant rate for any given species (Hisaw, 1947). This cannot be accelerated by increasing doses exogenous FSH (Davis Hellbaum, 1944). The developing to maturity also each but can increased addition (Brambell, 1956). As seems require certain amount maturation, release from may (Evans Simpson, 1940). Thus, needed normal ovarian response varies with different species. Too much or too little will cause many few develop mature.
