IGCSE Biology – Human Reproduction Practice Test

Question: 1 / 400

What does the corpus luteum primarily produce?

Testosterone

Oestrogen

Progesterone

The corpus luteum primarily produces progesterone, which is essential for preparing the endometrium (the lining of the uterus) for a potential pregnancy. After ovulation, the ruptured follicle transforms into the corpus luteum, which secretes progesterone. This hormone plays a crucial role in maintaining the uterine lining, making it suitable for implantation of a fertilized egg. If pregnancy occurs, progesterone helps sustain the early stages of gestation. Should fertilization not happen, the corpus luteum degenerates, leading to a decrease in progesterone levels and ultimately resulting in menstruation. The production of progesterone by the corpus luteum is a key aspect of female reproductive health and hormone regulation.
