Question

(b) For successful pregnancy, at what phase of the menstrual cycle an early embryo (up to 3 blastomeres) should be implanted in the Uterus (IUT) of a human female who has opted for Assisted Reproductive Technology (ART)? Support your answer with a reason.

Hint:

The luteal phase ensures optimal uterine conditions for embryo implantation due to high progesterone levels.

Answer 1

\begin{itemize} \item Phase: Luteal phase (Day 15–28). \item Reason: The endometrium is thick and rich in blood supply during this phase, suitable for embryo implantation and nourishment. \end{itemize}
