But recently I stumbled upon a saying by Prophet Muhammad, that the sex of the embryo is determined between 40-45 days of gestation. To a common man, it may seem contradicting to what we mentioned in the beginning. But as person who considers the sayings of Prophets (Whether it be Jesus, Moses, Buddha or Krishna - Considering them to be messengers of peace and love) to transcend time, it had to be true.
It must be surprising to know that after fertilization the embryo is sexually indifferent up to a certain period of gestation. Then a gene called SRY (Sex determining region) is activated. This gene is located in the short arm of Y chromosome (Yp). It codes for a protein called SRY protein (or Testis determining factor TDF). This protein further activates certain genes that causes development of male genital organs. While in absence of SRY protein, female genital organs develop and believe it or not, the SRY gene is activated at 6 weeks, i.e. 42 days to be precise.
Thus something that was mentioned centuries before, that was not accepted by the science of that age, is confirmed by the science of today.
Science changes with time but it's interesting how old foretold facts stand true over the course of time! :D
