masturbating
No. Once the sperm is in the egg no other sperm is allowed in.
The food you eat will have no effect on sperm determination.
This can be consdiered a form of birth control. Sperm in the mouth does not cause pregnancy. Sperm elsewhere can. Keep the sperm where it will do the least harm.
No it does not and it does not work for abortion either. There are no pills you can take that kills sperm.
Actually its takes a matter of seconds to produce a sperm. Millions of sperm are produced in a day.
There are no home remedies that you can take to increase the number "male" or "female" sperm in men as both are produced in equal amounts. The male DNA contains an X and a Y chromosome. When sperm is formed a single cell is split into two sperm, one takes the X chromosome (the "female" sperm) and one takes the Y (the "male" sperm).
It takes about 74 days for the male body to produce sperm.
Viagra
yes
No. How could it.
You cannot "take out sperm easily" from someone's body. You did not say if the 14 year old is a male or a female. If a male, they must ejaculate to "take out" sperm. If they are female, they can try a douche, but once the sperm is inside the vagina, it swims away up the fallopian tubes and cannot be washed out.
I take abilify for psychosis and since i ve been taking it i have very low sperm.
