What occurs during the secretory phase of the uterine cycle?

Ovulation occurs, releasing an egg from the ovary.

The endometrium sheds, leading to menstruation.

The follicular phase begins, stimulating follicle development.

The endometrium thickens and secretes nutrients to prepare for potential implantation.

Verified step by step guidance

Understand the uterine cycle: The uterine cycle is divided into three phases: the menstrual phase, the proliferative phase, and the secretory phase.

Identify the secretory phase: This phase occurs after ovulation and is primarily influenced by the hormone progesterone, which is secreted by the corpus luteum.

Recognize the role of progesterone: Progesterone causes the endometrium (the lining of the uterus) to thicken and become more glandular, preparing it to support a potential pregnancy.

Note the changes in the endometrium: During the secretory phase, the endometrial glands enlarge and secrete nutrients, creating a supportive environment for a fertilized egg to implant.

Connect to the overall cycle: If implantation does not occur, the corpus luteum degenerates, leading to a decrease in progesterone and the onset of menstruation, marking the end of the secretory phase.
