Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The corpus luteum secretes progesterone, which maintains the endometrial lining for potential embryo implantation and supports early pregnancy until the placenta takes over. This function is essential for 'retention of pregnancy'. Childbirth is triggered by oxytocin, ovulation is caused by LH surge, and milk production is stimulated by prolactin - not corpus luteum functions.

Multiple choice
  1. Estrogen builds up the lining of the uterus.

  2. Progesterone secretion decreases after ovulation.

  3. A drop in progesterone causes the lining to break down.

  4. The menstrual cycle is from day 1 of bleeding to day 1 of the next time of bleeding.

  5. About once a month, the uterus grows a new lining to get ready for a fertilised egg.

  3. Dysgerminomas

  4. Malignant teratoma
