What Harmones Affect Fertility?

What are hormones?

Hormones are chemicals that are produced by the body and control the function of different organs and tissues. They are responsible for many body processes such as growth, development, reproduction and mood.

There are many different hormones that affect fertility, but some of the most important ones are:

Follicle stimulating hormone (FSH): This hormone is responsible for the development of the ovarian follicles ( sacs that contain the eggs) and the production of estrogen.

Luteinizing hormone (LH): This hormone is responsible for the production of progesterone and the regulation of the menstrual cycle.

Estrogen: This hormone is responsible for the development and maturation of the eggs, as well as the thickening of the uterine lining in preparation for implantation.

Progesterone: This hormone is responsible for the maintenance of the uterine lining, and the development of the placenta.

What hormones affect fertility?

There are many hormones that play a role in fertility. The most important hormones are estrogen and progesterone. These hormones are responsible for the menstrual cycle and ovulation. Other hormones that play a role in fertility include follicle-stimulating hormone (FSH), luteinizing hormone (LH), testosterone, and thyroid hormone.

How do hormones affect fertility?

The most well-known hormones involved in fertility are estrogen and progesterone, which are produced by the ovaries. However, other hormones, such as testosterone and thyroid hormones, can also play a role in fertility.

If there is too much or too little of a particular hormone, it can impact fertility. For example, too much testosterone can interfere with ovulation, while too little thyroid hormone can lead to infertility.

Hormones can also affect fertility through their impact on the body's metabolism. For example, thyroid hormones help to regulate the body's energy production, and changes in thyroid hormone levels can impact how efficiently the body produces energy. This can then affect ovulation and fertility.

So, how do hormones affect fertility? Hormones can impact fertility through a variety of ways, including their impact on the ovaries, metabolism, and other body systems.


The hormones that affect fertility are estrogen, progesterone, follicle stimulating hormone (FSH), and luteinizing hormone (LH). If there is a problem with any of these hormones, it can affect fertility.
