Does having more female zw affect fertility?

Patient's question:

No

Doctor's answer:

Many women use their fingers for masturbation. Fingers are inevitably contaminated with many bacteria due to contact with various objects, especially in the gaps between the nails where dirt and bacteria accumulate, leading to long-term consequences. After marriage, it can severely affect the movement of eggs and sperm, as well as the implantation of fertilized eggs, resulting in infertility or ectopic pregnancy.
