The Sperm Meets Egg Plan: Getting Pregnant Faster
About this deal
When the nucleus of a sperm and egg fuse together, the egg is fertilised and it develops into a fetus. You’ll probably release fewer than 500 eggs during your fertile years, between your first period and menopause. The Sperm Meets Egg Plan is a step-by-step guide to achieving pregnancy without taking invasive tests, charting temperatures, or making mistakes in predicting your ovulation that result in mistimed attempts at fertilization.
Gametes have adaptations to increase the chances of fertilisation and successful development of an embryo .
Structural analysis of these proteins separately and in complex provides insight into the recognition process and the subsequent sperm–egg fusion. In men, an orgasm propels sperm-rich semen into the vagina and up towards the cervix at roughly 10 miles per hour.

During ejaculation, the sperm pass through the sperm duct and combine with seminal fluid produced by the glands to create semen, which exits the body through the penis. The function of the male reproductive system is to produce sperm cells - male gametes - and release them inside a female. Many eggs begin dying off almost immediately and the rest steadily decrease in number and quality as you get older.
