Infertility is of two types.

    Types of infertility: Infertility is divided into two parts:

    1. Primary infertility      2. Secondary infertility

     

    Primary infertility refers to those who have never been able to get pregnant or conceive a child at least after 1 year of regular unprotected sex. Also, women’s having regular miscarriages or whose pregnancy results in a stillborn child are referred to have primary infertility.

    Secondary infertility refers to those couples who are now unable to conceive after getting conceive already once.

    Causes of Infertility

An intensive form of exercise, anorexia or any other form of injury can also interfere with ovulation.

    Disorders of uterus or cervical: This includes abnormalities with the opening of the cervix. Presence of Benign tumors and fibroids in the uterine can result in blockage of the tubes and interferes with fertilization of egg and embryo formation. This results in infertility.

    Damage or Blockage in the Fallopian tube: The inflammation in the fallopian tube can result in infertility.Endometriosis or adhesions are sexually transmitted infections which can result in inflammatory disease leading to infertility.

    Endometriosis: This is the condition in which growth of tissues take place outside of the uterus lining affecting the normal functioning of the uterus, ovaries and fallopian tubes.

    Pelvic adhesions: In this condition, the bands of scar tissue causes the internal organs to stick together in the pelvic area resulting in pelvic pain. Previous surgical procedures can also lead to adhesions. Adhesion can block or distort the fallopian tube resulting in infertility.

    Early Menopause or ovarian insufficiency: In this condition, menstruation cycle ends before the age of 40 and ovaries stop working and. The exact cause is unknown. Diseases of the immune system, smoking, certain genetic disorders and radiation treatment or chemotherapy treatment are certain factors which can result in early menopause.

    Other causes are as under:

    Cancer disease and its treatment: Radiation and other therapies such as chemotherapy done during cancer treatment may affect ovulation. Cancer particularly reproductive cancer can be a cause of infertility.

    Sexual disorder: Erectile disorders, spinal cord injury, prostate surgery, premature ejaculation, Failure of ejaculation can result in sexual disorders leading to infertility.
