Prior to Ovulation,the Primary Steroid Hormone Secreted by the Growing

Question

Prior to ovulation,the primary steroid hormone secreted by the growing follicle is
A)LH.
B)FSH.
C)inhibin.
D)GnRH.
E)estradiol.

Accepted Answer

Prior to ovulation, the dominant hormone secreting by the growing follicle is estradiol. This hormone is responsible for preparing the uterus for potential implantation and promotes the secretion of luteinizing hormone (LH), which triggers ovulation. It also inhibits the secretion of follicle-stimulating hormone (FSH) and gonadotropin-releasing hormone (GnRH) to prevent the growth of additional follicles. Inhibin is also secreted by the follicles, but its role is to inhibit FSH secretion, rather than being the primary hormone secreted.
