The corpus luteum is formed at the site of:
a. Fertilization
b. Ovulation
c. Menstruation
d. Implantation

Verified step by step guidance
1
Understand the role of the corpus luteum in the female reproductive system: it is a temporary endocrine structure involved in hormone production after ovulation.
Recall the process of ovulation, where a mature ovarian follicle releases an egg from the ovary.
Recognize that the corpus luteum forms from the remnants of the follicle after the egg has been released during ovulation.
Eliminate other options by understanding their timing and processes: fertilization occurs after ovulation, menstruation is the shedding of the uterine lining, and implantation is the embedding of the fertilized egg into the uterine wall.
Conclude that the corpus luteum is formed at the site of ovulation, where the follicle transforms into this hormone-secreting structure.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Corpus Luteum Formation

The corpus luteum is a temporary endocrine structure formed in the ovary after ovulation. It develops from the ruptured follicle and secretes progesterone to support the early stages of pregnancy.

Ovulation

Ovulation is the process where a mature ovarian follicle releases an egg into the fallopian tube. This event triggers the transformation of the follicle into the corpus luteum.

Role of Progesterone

Progesterone produced by the corpus luteum prepares the uterine lining for potential implantation and maintains early pregnancy. Without the corpus luteum, progesterone levels drop, leading to menstruation.
