💜 Reproductive hormones work as a team, interacting with each other. Each has to be produced at a certain time, to allow several aspects of the reproductive cycle work as expected: the follicles to grow and mature, the egg to be ovulated, and the uterus lining to be ready for implantation.
Swipe to learn the role of each hormone in this team.👆
🪺 AMH: Your ovarian reserve snapshot
AMH (Anti-Müllerian Hormone) is produced by small follicles that contain the eggs in the ovaries.
As women are born with all the eggs they will be able to use, earlier in life, AMH levels are high and as time goes by, reduces. In simple terms, it gives an estimate of how many eggs remain.
🩸 FSH: How hard your body work to stimulate the ovaries
FSH (Follicle Stimulating Hormone) is released by the brain to tell the ovaries to grow eggs. When ovarian reserve declines, the brain turns up the volume, meaning FSH rises. It’s one of the earliest signals that fertility is changing.
✨ LH: The ovulation trigger
LH (Luteinizing Hormone) helps with the latest stages of egg maturation and surges just before ovulation. Measuring LH helps confirm if and when ovulation happens. Helpful for cycle tracking, timing pregnancy, and diagnosing ovulation disorders.
🥚 Estradiol: The egg-growth hormone
Estradiol is produced by growing follicles in the ovaries.
It helps:
- mature eggs
- prepare the uterine lining
- regulate the menstrual cycle
- Measuring it adds crucial context to FSH and LH.
🧬 Progesterone: The implantation supporter
After ovulation, progesterone prepares the uterus for pregnancy.
Low progesterone can mean:
- Ovulation didn’t occur
- Or the luteal phase is too short
-Essential for understanding cycle health.
👩⚕️ Prolactin: The unexpected disruptor
-Prolactin is best known for milk production, but when elevated, it can stop ovulation entirely.
-Many people don’t realize a simple blood test can identify this hidden cause of cycle disruption.
-Small test. Big clarity.
