Female infertility can be also be caused by a number of factors, including the following: Damage to fallopian tubes. Damage to the fallopian tubes (which carry the eggs from the ovaries to the uterus) can prevent contact between the egg and sperm.
Ovulatory or Hormonal Disorders : Major cause of infertility in females is failure to ovulate which includes Polycystic Ovarian Syndrome (PCOS), blocked fallopian tubes and the production of antibodies to a partner's sperms. However, problems can also arise if the ovaries themselves are resistant to normal levels of hormones. In addition, absent, damaged or diseased ovaries will prevent ovulation.
Generally, age and fertility are inversely related, and aging of the reproductive system is the other major cause of female infertility. The most rapid decline in fertility in particular year has been found to occur at age 35. Decline in fertility also seems to be a direct result of the age-related decline in the number of healthy eggs in woman's ovaries.
The single most common cause of infertility in females is the failure to ovulate. Over 40% of women who are infertile suffer from ovulatory problem. The normal ovarian cycle is so complex that even small deviations can disrupt the cycle and prevent ovulation. Ovulatory disorders are often caused by deficiency in one of the controlling hormones. However, problems may also arise if the ovaries themselves are resistant to normal levels of hormones. In addition, absent, damaged or diseased ovaries results in failure of ovulation.
Disorder of the female is a more common phenomenon compared to those of male. This specially true in case of infection and inflammatory conditions. Due to its anatomy, the female genital tracts are more vulnerable to pathogens than the male tract.
Infertility can also arise in disorders where there is an abnormal number of sex chromosomes. For example, missing X chromosome results in a condition known as Turner’s Syndrome, which only affects females. The symptoms of this condition include shortness of stature, absence or very retarded development of secondary sexual characteristics.
