The pituitary gland produces the hormone follicle stimulating hormone (FSH), which is crucial for both men and women in the development of sperm and eggs.

FSH increases the growth of follicles within the ovaries in the first half of the menstrual cycle in women.

Oestradiol is a female steroid hormone that is made primarily in women's ovaries and only little in men's testicles.

The female reproductive system, breast tissue growth, and bone density are all influenced by this, the strongest of the three oestrogens. Oestradiol levels in premenopausal women fluctuate during the monthly cycle, reaching their highest point at ovulation.

Oestradiol levels in women decrease with ageing, peaking at menopause when the ovaries stop releasing eggs. Low oestradiol can induce several symptoms associated with the menopause, including hot flushes, nocturnal sweats and mood swings. Osteoporosis can also result from low oestradiol.

A steroid hormone, progesterone is created in the corpus luteum and the adrenal glands. Its primary function is to get the body ready for and sustain a pregnancy.

In the second half of the menstrual cycle, it is produced in increasing numbers. On day 21 of your menstrual cycle, a progesterone test is typically performed to determine whether ovulation has occurred.

Progesterone is made in the testicles and adrenal glands of both men and women, despite the fact that it is generally thought of as a female hormone. In men, progesterone contributes to the creation of testosterone.
