Final answer:
Estrogen and progesterone are the two influential hormones in the female fertility cycle.
Step-by-step explanation:
The two influential hormones in the female fertility cycle are estrogen and progesterone. FSH stimulates the development of egg cells and follicles, which produce inhibin. LH plays a role in the development of ova, induction of ovulation, and stimulation of estrogen and progesterone production by the ovaries. Estrogen produces secondary sex characteristics and both estrogen and progesterone regulate the menstrual cycle.
