What day of the cycle is the progesterone highest?

Progesterone is a steroid hormone that is produced in the corpus luteum, and present in the ovaries.

1. It maintains the endometrial layer and helps in preparing the uterus for pregnancy.
2. Progesterone is secreted by the ovaries after the ovulation phase (10-12 days before the onset of the menstruation cycle).
3. During ovulation, a mature egg is released by the ovaries.
4. Hence, the progesterone levels are at their peak 6-8 days after ovulation.
