Final answer:
Low response to IVF is associated with various hormonal factors such as AFC, AMH, FSH, and LH, where FSH and LH are regulated by GnRH. These hormones play key roles in the maturation and ovulation of ovarian follicles, crucial for successful IVF treatment.
Step-by-step explanation:
The question pertains to the factors influencing low response to IVF (in vitro fertilization). To answer the question, various hormones are considered, such as antral follicle count (AFC), anti-Müllerian hormone (AMH), follicle-stimulating hormone (FSH), and luteinizing hormone (LH). These hormones are critical in the reproductive cycle, particularly in the stages leading up to ovulation.
FSH and LH are regulated by gonadotropin-releasing hormone (GnRH), and they stimulate the maturation of ovarian follicles leading up to ovulation. In terms of IVF, a low response could be due to low AMH or AFC, or high basal levels of FSH, indicating diminished ovarian reserve. LH works in conjunction with FSH to facilitate the final maturation and ovulation of follicles.
Regarding the regulation of FSH and LH secretion, they are primarily regulated by GnRH secreted by the hypothalamus, and the interaction between these hormones ensures the proper functioning of the menstrual cycle and ovulation, which is imperative for successful IVF outcomes.
