Question

Quizplus · Accepted Answer

The menstrual cycle needs to be blocked during pregnancy to prevent the blastocyst from being lost. The endometrial lining thickens during the menstrual cycle to prepare for a potential pregnancy. If fertilization occurs, the blastocyst implants in the lining and starts to grow into a fetus. If the menstrual cycle were to continue, the lining would shed and result in the loss of the blastocyst. Therefore, the menstrual cycle needs to be blocked during pregnancy to ensure the survival and development of the fetus.
