Why are so many sperm released if only one is needed to fertilize an egg?
Getting more of your sperm closer to an egg means there is a greater probability that it will be you and not your neighbor fertilizing it.
This kind of competition is an evolutionary imperative for males of any species.
If a rival’s sperm fertilizes an egg, then an opportunity to pass on your genes is lost..
What does male sperm do to a woman’s body?
THERE’S more to semen than sperm. In many animals, seminal fluid alters both the bodies and sometimes even the behaviour of females. Human semen, too, triggers changes in the uterus, and might have wider effects on women, aimed at just one goal.
Do Babies always have the father’s blood type?
No it doesn’t. Neither of your parents has to have the same blood type as you. For example if one of your parents was AB+ and the other was O+, they could only have A and B kids. In other words, most likely none of their kids would share either parent’s blood type.
How many minutes does it take a man to release sperm?
Most men ejaculate within a few minutes of starting to thrust during intercourse. Men with delayed ejaculation may be unable to ejaculate or may only be able to ejaculate with great effort after having intercourse for a long time (for example, 30 to 45 minutes).
What happens when two different sperms meet?
What happens when sperm from two different males meet up? … Incapacitation is slightly different because it does not even require the sperm of the second mate. Instead, something in the seminal fluid destroys the ability of the first sperm to perform its duty of fertilising eggs.
Does putting legs up help get pregnant?
Sperm are pretty good swimmers. Once deposited in the vagina, they can reach the cervix within 15 minutes. Though you don’t need to raise your legs in the air after sex, or even lie flat on your back to help them get there, it can’t hurt.

Can one baby have two fathers?
Superfecundation is the fertilization of two or more ova from the same cycle by sperm from separate acts of sexual intercourse, which can lead to twin babies from two separate biological fathers. The term superfecundation is derived from fecund, meaning the ability to produce offspring.
How do you know when the sperm meets the egg?
It will be thick, sticky and white or opaque in colour and your vagina will feel quite dry. As sperm require mucus to help meet the egg, there is little chance of getting pregnant at this stage.
What happens if two sperm fertilize egg?
Fraternal twins are formed when two eggs meet two sperm in the womb. Each is fertilized independently, and each becomes an embryo. With identical twins, one egg is fertilized by one sperm, and the embryo splits at some later stage to become two. … The genes could have then been muddled up before the egg fully separated.
Can unhealthy sperm fertilize an egg?
While healthier sperm ideally should fertilize an egg, sperm with damaged DNA can also fertilize — which may result in problems for the fertilized, developing egg.
How soon after unprotected can I test for pregnancy?

For pregnancy to happen, the egg must be fertilised by a sperm within this time. Sperm can live for up to 7 days inside a woman’s body.

Some women experience mild implantation cramping several days after ovulation, while others do not. Why might you feel cramping? To achieve pregnancy, the fertilized egg must attach to the uterine lining.
