The hormone primarily responsible for ovulation is luteinizing hormone (LH).
Understanding Ovulation and LH
Ovulation, the release of a mature egg from the ovary, is a crucial part of the menstrual cycle. This process is triggered by a surge in luteinizing hormone (LH) produced by the pituitary gland. This LH surge stimulates the final maturation of the egg and causes the follicle to rupture, releasing the egg.

LH's Role: LH doesn't just trigger ovulation; it also plays a vital role in the production of other hormones necessary for pregnancy, such as estrogen and progesterone. A blood test measuring LH levels can be used to diagnose fertility issues or irregular menstruation. [Source: Cleveland Clinic]

Other Hormones Involved: While LH is the primary trigger, other hormones, like follicle-stimulating hormone (FSH) and estrogen, contribute to the process leading up to ovulation. FSH stimulates follicle growth, while estrogen prepares the uterine lining for potential implantation. [Source: UCSF Health, Forthwithlife]

Progesterone's Post-Ovulation Role: It's important to note that while progesterone is crucial for preparing the uterine lining for a fertilized egg (implantation) and maintaining a pregnancy, it does not directly trigger ovulation. [Source: Proov Test, StatPearls, Medical News Today]
Clarification on Misconceptions
Some sources incorrectly or incompletely state that progesterone is responsible for ovulation. This is inaccurate. Progesterone is vital for the post-ovulation phase of the cycle, preparing the uterus, but it does not initiate the egg's release. [Source: Proov Test, StatPearls]
