As said above, numerous medical studies have proved that woman’s fertility dramatically decreases after age 35, since every woman is born with the unique supply of eggs during her lifetime until they stop producing them in menopause, while the effect on male fertility is only minimal, and men produce continuously sperm throughout their lives.

Woman has the most fertile eggs in her teens until her late 20’s. When woman reaches 30’s her eggs have a potential of fertilization, but it is decreased.  Reason for this is chromosomal injuries that are much more common with increased woman’s age.

Additionally, age is also related to increased number of miscarriages, especially when approaching the age of 40. This problem is mostly related to chromosomes and cellular machinery of eggs, there is little it can be done to turn back this biological clock.

For example, in woman younger than the ‘critical age’ of 35 the majority of ovulated eggs have normal composition of chromosomes, but as woman gets older than 35, the increasing number of her eggs get abnormal with the main reason lying in the natural process of aging when egg quality and quantity declines.
