The Female Partner

Common factors related to the female partner are:

  • Problems with the ovaries or lack of regular ovulation, which is the development or release of a healthy egg.  These may be caused by endocrine disorders such as Polycystic Ovarian Syndrome (PCOS) that can result in irregular menstrual cycles including prolonged, infrequent or lack of periods; infertility; or recurrent miscarriages.
  • Problems with the fallopian tubes, the uterus, or other pelvic organs.  Examples include:
    • Damage to the fallopian tubes that affects the movement of the egg into the uterus
    • Endometriosis, where tissue normally found on the inside of the uterus is found on the outside of the uterus and can cause scarring and anatomical abnormalities that disrupt the menstrual cycle.
    • Fibroids, or uterine tumors, forming the muscle of the uterus and distorting the uterine cavity and interfere with conception.
    • Hormonal abnormalities, where certain imbalances can affect the ability to produce a healthy egg.
    • The woman’s age.  Experts now believe that a woman’s ability to conceive begins to decrease approximately 10 years before the onset of menopause, which varies from woman to woman, but in general starts at age 35.
