PREGNANCY Hit and miss
Sperms and egg race
Sexual intercourse does not always result in a new life being conceived. The egg can only be fertilized in the 12 to 24 hours immediately after the woman ovulates.
For the egg to be fertilized, a man's sperm must reach the woman's egg when it is moving down the Fallopian tube, halfway through the woman's menstrual cycle.
When sperm are ejaculated during intercourse, they land near the woman's cervix, the neck of her uterus.
Sperm look like microscopic tadpoles, and they swim up the uterus by waggling their tails.
As the sperm approach the egg, their heads dissolve in chemicals released by the egg. But as many heads dissolve, they send out an enzyme that helps one sperm to penetrate the egg.
It takes the enzymes of hundreds of sperm to break down the egg's protective barrier but one sperm may finally make it through and only one is required fir fertilization...
Pregnancy begins when egg and sperms unite. The multiplying egg cells travel down the fallopian tube to the uterus and now gets implanted on the mother’s uterus, and the fetus grows.
The uterus grows larger to allow growth of the baby and the size of the baby is shown from 4 weeks to 20 weeks.
The growth of the baby can now be confirmed on ultrasound scan. The sex of the baby can also be confirmed.
