The idea that a man's genes remain in a woman after sex is a misinterpretation of scientific findings and is not accurate in the way it is sometimes portrayed in popular media.
Scientifically Accurate Summary:
1. No, a man's full genetic material (DNA) does not remain in a woman after intercourse in a general or lasting way.
During sexual intercourse, sperm cells enter the female reproductive tract, but unless fertilization occurs, these cells typically die and are cleared from the body within a few days.
2. Sperm Lifespan:
Sperm can survive in the female reproductive system for up to 5 days under optimal conditions (such as during ovulation).
After that, the immune system clears them out.
3. Exception – Microchimerism (rare case):
There is a rare phenomenon known as microchimerism, where small numbers of cells from one individual can be found in another individual’s body.
This most often occurs during pregnancy—for example, fetal cells can remain in a mother’s body for years or decades.
There have been very limited and controversial studies (e.g., in mice or on postmortem brain tissue) suggesting that male cells might be found in women who have had male pregnancies—but these are not linked to sexual intercourse.
4. No Evidence From Intercourse Alone:
There is no credible scientific evidence to support the claim that intercourse alone results in the long-term retention of male DNA or genetic material in a woman's body in a meaningful or functional way.

Conclusion:
From a scientific and clinical standpoint, a man's genes do not remain in a woman after sex beyond the short life of sperm cells (typically a few days). Any claims beyond that are either based on misinterpreted science or pseudoscience.
If you’re inquiring for health, reproductive, or psychological reasons, feel free to elaborate so I can tailor the information more appropriately.
