Postponement of pregnancy after marriage is crucial factor that has led to increase in worldwide infertility rates. Today the average age of a woman who first gives birth has increased by three years more than two decades earlier.
Age related infertility is very common among women as the ovarian reserves start to shrink as women approach their menopause. The quality and number of eggs produced in the ovaries decline with age making it difficult to conceive for women over the age of 35. At the age of 35 the ovarian reserve is almost half than that at the age of 25. By the time a woman is 45, she will have less than 5% chances of conceiving and is 70% more likely to have a miscarriage.
Another major factor affecting female infertility includes body weight which accounts for 12% cases. Being either over weight or under weight equally affects the chances of conception. Thyroid disorders causing abnormal BMI (Body Mass Index) and lifestyle factors like smoking, drinking and stress also contribute towards infertility.
