Doctors for years believed 28 days was average; they now know teens average is closer to 40 days, 20 - 29 average is 35 days, 30 - 39 average is 30 days and not until a woman is in her 40's does she hit the mythical 28 day cycle.

They have also found that only 30% of women ovulate at the mid point of her cycle, 30% is days after and 30% is days before - 10% is "other".

Fertilization normally takes place in the?

Fertilization normally takes place in the fallopian tubes of the female reproductive system. Sperm travels through the vagina and cervix into the uterus, then into the fallopian tubes where it may encounter and fertilize an egg released from the ovary.


Why are there only a few days in each menstrual cycle when fertilisation can take place?

In order for fertilization to take place, there must be an egg available to be fertilized. So, fertilization can take place between an egg being released, travelling down the fallopian tube, and arriving at the uterus. Once an egg arrives at the uterus, if it is not fertilized, then the body takes steps to get rid of it (menstruation). It only takes a few days for the egg to get to the uterus after being released, so those few days are the only ones when the egg can be fertilized.
