Does the man's semen determine the sex of the fetus, and when should a husband have intercourse with his wife after the end of menstruation to conceive a female or a male?

It has been scientifically proven that the sex of the newborn is determined by the man's sperm. If a sperm carrying the male chromosome meets the egg, the fetus will be male. If it carries the female chromosome, it will be female. This aligns with the Almighty's saying: (And that He creates the two sexes, the male and the female From a sperm-drop when it is emitted). To determine the probable days for conceiving a male, medical consultation should be sought.
