No, sperm are required for pregnancy.
If sperm enters the female reproductive tract during infertile days, it typically does not result in pregnancy, as there is no egg available for fertilization. Sperm can survive in the female body for several days, but without ovulation, the sperm will eventually die off without achieving fertilization. The timing of ovulation is crucial for conception, making days outside the fertile window less likely to result in pregnancy.
No, sperm doesn't cause early miscarriage.
Not unless you can transfer sperm from your mouth down into her eggs.
Not normally, no. It could only cause pregnancy if there was sperm on his fingers. However, even if he did it would be unlikely to cause pregnancy. Still, it is important to make sure there is no sperm on his fingers if he is going to touch her.

Yes it could cause a ZERO sperm count. I have been on Zoloft (Sertraline) for 3 years and my sperm count is extremely low. So in essence it makes you infertile for the duration of use and possibly beyond.
