Vedclass · Answer

(A) During the menstrual cycle,the levels of pituitary hormones ($LH$ and $FSH$) and ovarian hormones (estrogen and progesterone) fluctuate in a specific pattern.$1$. The $LH$ surge occurs around the $14^{th}$ day of the cycle,which triggers ovulation.$2$. After ovulation,the corpus luteum is formed,which secretes large amounts of progesterone.$3$. Consequently,progesterone levels rise significantly during the luteal phase (days $15-28$) to maintain the endometrium.$4$. Comparing the given graphs,the graph in option $A$ correctly shows the $LH$ surge at day $14$ and the subsequent rise in progesterone levels during the luteal phase.
