One way to empower women throughout their fertility journey is to provide accurate information and demystify confusion with better education. Many women learn about hormones during their fertility cycle but only know what the hormones are called – not the function or where they are produced. 

In an effort to support the fertility community we serve, let’s breakdown hormonal regulation to better understand how it all works and relates to your fertility cycle.

What areas in the body are involved in hormonal regulation of the female reproductive cycle?

Hypothalamus – Located at the base of the brain, the hormone involved is called GnRH or gonadotropin-releasing hormone. Think of GnRH as the master hormone that initiates the ovarian cycle. The hypothalamus triggers the pituitary gland to secrete LH and FSH.

Pituitary Gland – Located at the cranial cavity (the base of the brain), the hormones involved include: FSH (follicle-stimulating hormone), LH (luteinzing hormone), and Prolactin. FSH stimulates the ovaries and promotes growth and development of the ovarian follicles (eggs). LH induces release of an ovum and triggers ovulation.

Ovaries – Located in the pelvic cavity, the hormones involved include: Estrogen and Progesterone. Together, these do a whole lot such as:

  • act in synergy with FSH to help promote growth and development of a primary follicle (egg)
  • prepare the uterus for pregnancy following ovulation
  • help prepare the endometrium of the uterus for implantation
  • help regulate the production and release of FSH and LH over in the pituitary gland

Why does an IVF cycle require so much monitoring with bloodwork and ultrasounds?

It’s clear by reading this that A LOT is going inside the female body every month. Fertility treatment involves a delicate balance of stimulation and careful medical monitoring to adjust to the individual’s response. Your fertility center likely provides personalized care with the goal of achieving the best possible cycle and result, as well as trying to avoid any serious side effects such as ovarian hyperstimulation syndrome.
