Question 1

after ejaculation how can sperm penetrate an egg?

Accepted Answer

Complex Interaction: When the sperm find the egg, many of them are required to get through the outer layers surrounding the egg.  Then a single sperm is allowed to fuse with the egg's cell membrane, at which time the genetic contents of the sperm are brought inside the egg.

Question 2

can sperm penetrate in on top of vagina?

Accepted Answer

Yes: Cervix as at top of vagina ; entrance to the uterus.

Question 3

can sperm penetrate two layers of clothing and cause pregnancy?

Accepted Answer

Unlikely: Sperm are very small as you know and could penetrate fabric. If the layers of fabric are very saturated with sperm, penetration would be theoretically possible but highly unlikely.

Question 4

can sperm penetrate a fabric like jeans to impregnate a woman? i saw a wet spot on my jeans from semen after dry humping my naked gf.

Accepted Answer

Highly unlikely: From what you described, it is not feasible for your gf to get pregnant.
For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. 
Practice safe sex.

Question 5

i and my bf having romance with thin clothes & too close to each other.can sperm penetrate via thin clothes .cloth were wetted bcz of spermatic fluid.also i was having that day last day of my menstrual cycle..so chance of pregnancy??

Accepted Answer

Highly unlikely: Above circumstances make pregnancy highly unlikely. In order to prevent undesired pregnancy and anxiety generated by its possibility always use contraception.

Question 6

my partner and i had dry humping. we both were just wearing pajamas without underwear. can pregnancy occur if my pre-ejaculate, or possibly sperms, come out? can sperm penetrate two layers of clothing and cause pregnancy?

Accepted Answer

Almost never: I hesitated to say completely never, as there is always one anecdote out in the world that would prove otherwise. To be safe and prudent going forward, use contraception as you never know when "dry" humping will "splashdown" into a "ocean" of fertile humping.

Question 7

sperm has to go through a process before being able to penetrate the egg?

Accepted Answer

Correct: Sperm need to prepare themselves for egg penetration by first undergoing the acrosome reaction (to expose the enzymes that will dissolve the egg shell covering the egg) and then capacitation, that allows them to actually penetrate the egg once the egg shell is traversed.

Question 8

how long does it take for sperm to penetrate an egg? hours after introduction of sperm? days? does abstaining from working out help keep it up there?

Accepted Answer

Sperm & egg: It takes the winning sperm anywhere from 30 minutes to 3 days to reach an egg. The egg has 24 hours after the sperm reaches it to be fertilized or it dies. There is no need to abstain from working out; it has no impact on sperm motility, but it does have other health benefits, so keep on working out.

Question 9

how long does sperm usually stay active in virginia to penetrate an egg ?

Accepted Answer

About 30 min, but..: The sperm does not fertilize the egg in the vagina.  This usually takes place in the fallopian tube or uterus, and sperm can last 4-7 days in there.  The vagina is a  less friendly environment for sperm to survive.

Question 10

can precum penetrate through jeans? and if does so will it still have alive sperms in it??

Accepted Answer

: The moisture may pass through, but sperm are fragile &amp; die in minutes when outside of the moist protective environment of the vagina. The chances of them being functional enough to trigger pregnancy approaches zero.
