Can sperm survive in menstrual blood?
Answered by 1 Apollo Doctors
Women are not able to conceive whilst on their period, but sperm survives within the female reproductive system for up to five days. This means that a tiny fraction of women do have a small chance of becoming pregnant during their period.

Sperm Survival in Menstrual Blood
Sperm survival in menstrual blood is generally limited. Menstrual blood creates an environment that is not very supportive for sperm due to its acidity and presence of immune cells. -
Optimal Conditions for Sperm Survival
Sperm typically survive best in cervical mucus around ovulation, which is more alkaline and nourishing. Under optimal conditions, sperm can survive inside the female reproductive tract for up to 5 days. -
Potential for Pregnancy
While sperm survival in menstrual blood itself is unlikely, if sperm enter the reproductive tract during menstruation, there is a small chance they could survive and potentially lead to pregnancy. -
Recommendation
If you have concerns about fertility or contraception, discussing with a healthcare provider can provide personalized advice.

I'm really worried because I took the meningitis B vaccine last month, and soon after I got really sick and had to go to the hospital. I'm 18, and on top of it all, my menstrual cycle seems delayed. I did a pregnancy test and it was negative, so I'm trying to figure out if the vaccine could be affecting my period. Is that a possibility?
no

I'm feeling a bit worried about my wife's situation. She's three months pregnant, just at the start of her 14th week. We live in a building where our apartment is on the third floor, and there's no lift. Every weekday, she has to go down 60 steps in the morning to head to the office, and then back up those 60 steps again in the evening. Is it safe for her and the baby to be doing this every day, or could it have any negative effects on her pregnancy? I'd appreciate any advice on this.
yes she can do no worries
