Sperm does not directly change a woman's hormones.
While sperm contains a small amount of hormones, these are not significant enough to affect a woman's hormonal balance.
The primary hormone responsible for pregnancy is human chorionic gonadotropin (hCG), which is produced by the developing embryo after fertilization.
This hormone is not present in sperm and is only produced after a successful conception.
Therefore, sperm does not directly influence a woman's hormones, and any hormonal changes experienced during pregnancy are due to the presence of hCG and other pregnancy-related hormones.
