Infertility Causes

• Ovulation disorders, meaning you ovulate infrequently or not at all.
• Irregular menstrual cycle (less than 21 days, more than 35 days) can lead to problem in getting pregnant.
• Polycystic ovary syndrome (PCOS). PCOS causes a hormone imbalance, which affects ovulation. PCOS is associated with insulin resistance and obesity, abnormal hair growth on the face or body, and acne. It’s the most common cause of female infertility.
• Hypothalamic dysfunction. Two hormones follicle-stimulating hormone (FSH) and luteinizing hormone (LH) are responsible for stimulating ovulation each month. Excess physical or emotional stress, a very high or very low body weight, or a recent substantial weight gain or loss can disrupt production of these hormones and affect ovulation. Irregular or absent periods are the most common signs.
• Premature ovarian failure. Also called primary ovarian insufficiency, this disorder is usually caused by an autoimmune response or by premature loss of eggs from your ovary (possibly from genetics or chemotherapy).
• Too much prolactin. The pituitary gland may cause excess production of prolactin (hyperprolactinemia), which reduces estrogen production and may cause infertility.

Damaged or blocked fallopian tubes keep sperm from getting to the egg or block the passage of the fertilized egg into the uterus. Causes of fallopian tube damage or blockage can include:

• Pelvic inflammatory disease, an infection of the uterus and fallopian tubes
• Previous surgery in the abdomen or pelvis, including surgery for ectopic pregnancy, in which a fertilized egg implants and develops in a fallopian tube instead of the uterus
• Pelvic tuberculosis, a major cause of tubal infertility worldwide, although uncommon in the United States

Endometriosis occurs when tissue that normally grows in the uterus implants and grows in other locations.

Several uterine or cervical causes can impact fertility by interfering with implantation or increasing the likelihood of a miscarriage:

• Benign polyps or tumors (fibroids or myomas) are common in the uterus. Some can block fallopian tubes or interfere with implantation, affecting fertility. However, many women who have fibroids or polyps do become pregnant.
• Endometriosis scarring or inflammation within the uterus can disrupt implantation.
• Uterine abnormalities present from birth, such as an abnormally shaped uterus, can cause problems becoming or remaining pregnant.
• Cervical stenosis, a narrowing of the cervix, can be caused by an inherited malformation or damage to the cervix.
• Sometimes the cervix can’t produce the best type of mucus to allow the sperm to travel through the cervix into the uterus.

Irregular intercourse, hectic life schedule: Getting pregnant requires physical and mental attention of the couple. Working couples need to give more quality time to each other before trying to go for treatment.

Sperm quality and quantity of Male partner are a noticeable factor in fertility success. The sperm quality, motility and quantity also effects many a times for getting results.
