Which hormones are part of the female reproductive system?

The hormones that are primarily involved in the female reproductive system include progesterone and oestrogen, both of which play crucial roles in regulating the menstrual cycle, fertility, and maintaining pregnancy. Progesterone is essential for preparing the uterine lining for implantation of a fertilized egg and maintaining pregnancy, while oestrogen is involved in the regulation of the menstrual cycle and development of female secondary sexual characteristics.

Androgens, while primarily recognized as male hormones, are also present and important in females, contributing to the regulation of sexual function and overall hormonal balance. Their presence ensures the proper functioning of the female reproductive system in conjunction with the main female hormones, progesterone and oestrogen.

In contrast, other hormones mentioned in the other choices, such as insulin and cortisol, do not serve the same reproductive roles within the female reproductive system. Insulin is primarily involved in regulating blood sugar levels, while cortisol is associated with stress responses. This delineation confirms that the combination of progesterone, oestrogen, and androgen is the most representative of the hormonal contributors to the female reproductive system.
