5 Key Hormones Involved in Female Fertility:
Follicle-Stimulating Hormone (FSH)
- Role: Produced by the pituitary gland, FSH is essential for the growth and maturation of ovarian follicles, which contain your eggs.
- Optimal Levels for a 35-Year-Old Woman: Measured on day 3 of your menstrual cycle, FSH levels should be between 3 to 9 milli-international units per milliliter (MIU/mL).
Luteinising Hormone (LH)
- Role: Also produced by the pituitary gland, LH regulates the menstrual cycle. The surge in LH triggers ovulation, releasing the mature egg from the ovary.
- Optimal Levels: On day 3 of your menstrual cycle, LH levels should be between 2 to 12 MIU/mL.
Estradiol (E2)
- Role: This form of estrogen is produced by the ovarian follicles. It regulates the menstrual cycle, prepares the uterine lining for implantation, and develops female secondary sexual characteristics.
- Optimal Levels: On day 3 of your menstrual cycle, estradiol levels should be between 25 to 75 picograms per milliliter (pg/mL).
Progesterone
- Role: Produced by the corpus luteum in the ovary after ovulation, progesterone prepares the uterine lining for implantation and supports early pregnancy. Low levels can lead to luteal phase defects, affecting fertility and pregnancy maintenance.
- Optimal Levels: In the luteal phase, around seven days post-ovulation, progesterone levels should be greater than 10 nanograms per milliliter (ng/mL).
Anti-Müllerian Hormone (AMH)
- Role: Produced by the granulosa cells of the ovarian follicles, AMH is a marker of ovarian reserve, reflecting the remaining quantity of eggs. Higher levels indicate a greater number of remaining eggs.
- Optimal Levels: For women in their mid-30s, AMH levels should generally be between 1 to 4.0 ng/mL.
