Time of Ovulation

There are various methods that can be used to calculate the time of ovulation occurence. However, bear in mind that these serve as a rough guide only

. Your menstural cycle Women ovulate about 14 days before the start of their next period. This is not the same as saying that ovulation takes place 14 days after the last period because the length of the menstural cycle varies. Women may have cycle as short as 21 days or as long as 38 days rather than the standard 28-day cycle. Cervical mucus The quantity and quality of your cervical mucus changes over the course of the menstural cycle. During the early part of your cycle the mucus tends to be sticky and opaque. As the ovulation approaches, your mucus becomes increasingly wet, slippery and may resemble egg white. Fluctuations in basal body temprature The term "basal body temprature" refers to the temprature of the body first thing in the moring, checking it in the bed itself. Typically, right before ovulation, your temp. will dip slightly, dropping below its usual pre-ovulatory range of 97.0° F to 97.5°F and then shooting up to post-ovulatory 97.6°F to 98.6°F. Ovulation Kits The day of ovulation can also be checked by using an over the counter ovulation prediction device. These test involes urine testing, if plenty of LH hormone is being produced, a chemical will change colour. This means you are likely to be ovulating. However, like all the methods, ovulation kits are not foolproof.

The Sperm Legacy

It only takes one sperm to fertilize an egg. When a man ejaculates during sexual intercourse, between 100 million and 300 million sperms are discharged into the woman's vagina-at about 45km(28 miles) per hour. Despite the fact that the semen that carries the sperm is alkaline , the vast majority are unable to survive in the acidic vaginal envoirnment. The last few superfit sperm proceed to the outside of the egg. Of these sperm, just one will brealk through the surface, leaving its tail behind. This is the movement of fertilization. In the instant that it occurs, the egg's surface becomes impenetrable to other sperm.
