Vedclass · Answer

(A) During the first trimester of pregnancy,the corpus luteum in the ovary is the primary source of progesterone,which is essential for maintaining the pregnancy. If both ovaries are removed during the first trimester,the source of progesterone is lost,leading to the termination of pregnancy (abortion). However,after the first trimester,the placenta takes over the role of producing sufficient progesterone to maintain the pregnancy. Therefore,if the ovaries are removed after the first trimester,the foetus continues to grow normally because the placenta provides the necessary hormones. Thus,both the Assertion and the Reason are correct,and the Reason correctly explains the Assertion.

$A$: If both the ovaries are removed after the first trimester of pregnancy,still there would be normal growth of the foetus.
$R$: After the first trimester,the placenta secretes sufficient progesterone.
