Supplements to promote fertility
We define fertility reproduction capability of living organisms and is represented by the number of children per individual. Fertility differs from fecundity that instead expresses the potential reproductive capacity of an individual.
The WHO, World Health Organization, also defines:
sterility the situation of a pair in which one or both members are suffering from a condition that does not make possible permanent physical conception. This occurs in cases of azoospermia, premature menopause or congenital absence of the uterus.
infertility, the situation of a couple, for reasons related to the man or woman can not get pregnant after a long period of constant relations and unprotected. The term infertility, and then does not refer to an absolute condition, but in a situation potentially resolvable and linked to one or more interfering factors.
The two terms therefore, sterility and infertility, are not synonymous.
Western populations have suffered a significant drop in fertility than in the past, mainly due to the recent habit of delaying the time of pregnancy for social and cultural reasons. It is estimated that each year in Italy there are 20,000 to 45,000 couples who have difficulty to procreate.
Link between fertility and age of woman and man
In women age affects more than the man.
Consider a typical situation, without conditions, with a regular cycle and targeted reports:
At age 15, a woman has a 40-50% chance of conceiving per cycle.
At age 25, the percentage is 30-35%.
At age 35, the percentage is 20-25%.
At 45 years, the percentage is 3-5%.
It 'important to note that the outward appearance does not coincide with the state of the reproductive organs: women develop at puberty a wealth of egg cells that is not renewed over time (unlike the male sperm that are produced again every 3 months) but even decreases over time and degrades more ova are old and most likely will have to carry with chromosomal abnormalities or have problems of cell division after fertilization.
In humans, on the other hand age affects fertility because fewer sperm are continuously produced by the male reproductive organs. The quantity and quality may, however, worsen with age.
