Fertility Fertility is the natural capability to produce offspring. As a measure, fertility rate is the number of offspring born per mating pair, individual or population. an egg bursts from the follicle and is released from the ovary. The egg then travels along the Fallopian tube where, at some point, it fuses with the sperm to form a single cell. The fertilised egg takes three days to travel to the uterus (womb), and during this time the cells continue dividing. The fertilised egg, now known as an embryo, implants itself in the endometrium (lining of the womb).
Human fertility depends on factors of nutrition, sexual behavior, consanguinity, culture, instinct, endocrinology, timing, economics, way of life, and emotions. Fertility differs from fecundity, which is defined as the potential for reproduction. A lack of fertility is infertility while a lack of fecundity would be called sterility.
