Fertilization of an egg with sperm can occur in vitro (in a test tube). Under proper conditions, a blastocyst will form after about 5 days. The blastocyst contains a group of cells called the inner cell mass. These cells are pluripotent, meaning they can differentiate into any cell in the human body. These are commonly referred to as "embryotic stem cells".

Well, if you and your friend were aardvarking in bed, you don't have much to worry about because the sheets would be changed and laundered.  Bye-bye proof.\n\nIf you were being creative and it wasn't in the bathtub or shower, it is there until it is washed away.\n\nSperm can live for 3 - 5 days in a hospitable environment.  If every womb were an ideal environment, there would be many more pregnancies.\n\nThe answer to the unasked question: while sperm can live for several days, there is only 24 hours for conception, UNLESS your partner does something biologically unusual, such as ovulate twice (source of fraternal twins).

keep your self fit and healthy make sure there is some fat in your diet - fat promotes sperm development\n\nsleep well and dont drink much coffee or alcohol\n\nkeep your boys cool and loose \n\nwhack off or have intercourse frequently to encourage turnover and get new sperm made but refrain for about 3-5 days before you want to work on conception

Yes, but only on a short term bases, after a couple of days of not ejaculating, your sperm count should go back up.

I think 3 to 10 ml.It's not the quantity, but the potency tht matters. Each ml has millions of Spermatozoon, of which 40% motility is good enough.\n\nAlso depends on the number of ejaculations in a given period of time.\n\nThe first one may result in a larger quantity, the second one a lot less, the third even lesser, that is asuming we are talking of young person and the time around 2-3 hours.

You should have learned this in high school.  Only men produce sperm.  Women produce the egg, which gets fertilized by the sperm.

None. They all let sperm come in.

I'm not entirely sure of the rate, but YES you can ABSOLUTELY get pregnant!  He doesn't even have to ejaculate at all.  Fluids are excreted throughout the act which do contain sperm.  Age is no factor at all.

depends on yours and the guys age..... a woman, if lubricated can do it over and over again...30-50 times in a 16 hours period is very possible....a guy should be able to do 15 times (reach orgasm) in the same time period...of course, the woman should be able to get him interested! now that would be at 20-35 years old.between 35 and 55 a normal guy should be able to do it 10 times....im 50 i recently did it 11 times in 12 hours!

i dont think theres an abnormal amount, as long as the man has the strength nd the ability.\n\nin women the eggs arent produced after birth nd then stop till puberty nd after that onwards one egg at a time per month matures nd is released\nbut in men the sperms are continously produced throughout life

The best time to conceive is 7 -10 days after the first day of your menstrual cycle. Keep in mind that sperm can live up to 48 hours after ejaculation. If you really want to get pregnant your best bet is to have sex every other day because it gives the sperm count a chance to elevate again.\n\nGood Luck !

No, I do not believe you are pregnant. As long as your cycle has been regular or predictable for the past few months, the timing you stated would not allow viable pregnancy. Sperm can live anywhere from 24-72 hours, but ovulation usually occurs after 14 days into your cycle. Ultimately, you should go on birth control, or inquire to your doctor about the morning afer pill if you do not want implantation of a fertilized egg in the future. Good luck.

There are theories in some religions that the production of a drop of sperm requires many drops of blood.  Some say 40, 80 or 100 drops.  There is no scientific basis for this.  Some people will claim it is a "scientific fact" but can't tell you where the research was done.
