Keeping this in view, is it really the first sperm that fertilizes the egg?
Once the sperm have entered the uterus, contractions propel the sperm upward into the fallopian tubes. The first sperm enter the tubes minutes after ejaculation. The first sperm, however, are likely not the fertilizing sperm. Motile sperm can survive in the female reproductive tract for up to five days.
Similarly, can I get pregnant if sperm touches the outside? You can get pregnant if you have intercourse and a male releases his sperm inside of your vagina. You can even become pregnant if you don't have vaginal intercourse! This can happen if a male releases his sperm outside of your body near your vagina because sperm can find their way to an egg.
Also to know, how do sperm know where the egg is?
Scientists believe sperm cells find a waiting egg cell via a couple of complex mechanisms. They swim toward higher concentrations of molecules released by the egg (known as chemotaxis) and toward the high-temperature areas of the woman's reproductive tract, where eggs are found (known as thermotaxis).
Which is the path of sperm from the testes to the urethra?
Sperm then travel through the vas deferens through up the spermatic cord into the pelvic cavity, over the ureter to the prostate behind the bladder. Here, the vas deferens joins with the seminal vesicle to form the ejaculatory duct, which passes through the prostate and empties into the urethra.
