Final answer:
Estrogens and progesterone control the last steps in follicle maturation in the female reproductive system, regulating the menstrual cycle and preparing the body for pregnancy.
Step-by-step explanation:
In the female reproductive system, the last steps in follicle maturation are controlled by estrogens and progesterone. Estrogens trigger the development of secondary sex characteristics and control the maturation of the ova, while progesterone assists in endometrial regrowth and inhibits the release of follicle-stimulating hormone (FSH) and luteinizing hormone (LH). These hormones work together to regulate the menstrual cycle and prepare the body for pregnancy.
