In demography and biology, fecundity is the actual reproductive rate of an organism or population, measured by the number of gametes (eggs), seed set, or asexual propagules. Fecundity is similar to fertility, the natural capability to produce offspring. A lack of fertility is infertility while a lack of fecundity would be called sterility.
Demography considers only human fecundity which is often intentionally limited through contraception, while biology studies all organisms. Fecundity is under both genetic and environmental control, and is the major measure of fitness. Fecundation is another term for fertilization. Superfecundity refers to an organism's ability to store another organism's sperm (after copulation) and fertilize its own eggs from that store after a period of time, essentially making it appear as though fertilization occurred without sperm (i.e. parthenogenesis).
Fecundity is important and well studied in the field of population ecology. Fecundity can increase or decrease in a population according to current conditions and certain regulating factors. For instance, in times of hardship for a population, such as a lack of food, juvenile and eventually adult fecundity has been shown to decrease (i.e. due to a lack of resources the juvenile individuals are unable to reproduce, eventually the adults will run out of resources and reproduction will cease).

CCC #2366: Fecundity is a gift, an end of marriage, for conjugal love naturally tends to be fruitful. A child does not come from outside as something added on to the mutual love of the spouses, but springs from the very heart of that mutual giving, as its fruit and fulfillment. So the Church, which is "on the side of life," teaches that "it is necessary that each and every marriage act remain ordered per se to the procreation of human life." "This particular doctrine, expounded on numerous occasions by the Magisterium, is based on the inseparable connection, established by God, which man on his own initiative may not break, between the unitive significance and the procreative significance which are both inherent to the marriage act."

I remade this to slow the text, change the music, and add a couple of images. Links to related abstracts are here: http://flagonlyrainbows.blogspot.com/2009/06/male-homosexuality-maternal-fecundity.html The statistical finding has been replicated in several studies. Of interest, it only seems to apply to right-handed younger brothers. The effect has been postulated to operate through a phenomenon described in the maternal immune hypothesis. Since female fecundity is not a universal explanation, other mechanisms must operate. Begin the Beguine by Cole Porter seemed appropriate. Orchestra: Artie Shaw

How do we measure up? U understand the amazing processes that gave us vertebrates smaller than a thumbnail and longer than a diesel locomotive. But what are the mechanisms of these adaptations, the evolutionary pressures that affect size, and the physical limits life can It is widely agreed that fecundity selection and sexual selection are the major evolutionary forces that select for larger body size in most organisms. The general, equilibrium view is that selection for large body size is eventually counterbalanced by opposing selective forces. While the evidence for selection favoring larger body size is overwhelming, counterbalancing selection favoring small body size is often masked by the good condition of the larger organism and is therefore less obvious.
