Progesterone - Restore Clinic

Progesterone is an important hormone that plays many crucial roles in the female reproductive system and pregnancy.

What Does Progesterone Do?

Some key functions of progesterone include:

• Prepares the uterine lining for implantation of a fertilized egg
• Maintains pregnancy by supporting the developing fetus
• Balances estrogen effects on the body
• Regulates the menstrual cycle and ovulation
• Helps development of breast tissue

Progesterone levels fluctuate throughout the menstrual cycle, peaking after ovulation occurs. If an egg is fertilized, the corpus luteum continues secreting high levels of progesterone to maintain the pregnancy in early stages before the placenta takes over.

Where Does Progesterone Come From?

In females, progesterone is mainly produced by the corpus luteum and placenta:

• Corpus luteum - Forms in the ovary after ovulation. Secretes progesterone to prepare for potential pregnancy.
• Placenta - If pregnancy occurs, the placenta takes over progesterone production at around 10-12 weeks gestation.

Smaller amounts of progesterone are also produced by the adrenal glands and brain.

When Are Progesterone Levels Tested?

Doctors may test progesterone levels in different cases, such as:

• To evaluate infertility or recurrent miscarriages
• To check if ovulation occurred
• To determine hormone imbalances
• To monitor high-risk pregnancies

If progesterone levels are low, doctors at Restore Clinic may prescribe progesterone medications or supplements. This can help supplement the body's natural progesterone to establish or sustain a pregnancy.

In Conclusion:

As a key reproductive hormone, progesterone plays indispensable roles in the menstrual cycle, fertility, and maintaining pregnancy from implantation through gestation. Progesterone production from the ovaries, placenta, and other sources is delicate and complex - but vital for reproductive health.
