Instead of getting overwhelmed by the misconceptions and myths listed above, it is important to identify the cause of infertility in order to get pregnant faster. Obviously a health care provider is the best person to help you learn more about your health/ reproductive issues.

Common Causes of Infertility in Women:

Most popular causes of infertility in women include:

  • Hormonal Aberrations:

Hormonal irregularities or abnormal rhythm is the most common cause of infertility in women. The cause of irregularity may be nutritional issues, environmental factors, medications and in some cases, no particular reason can be identified.

Your health care provider will order serial hormonal assays on selective days in your menstrual cycle, and in case of hormonal irregularity, proper treatment has to be employed after ascertaining the cause of hormonal aberration.

  • Chronic Genital Tract Infections:

Sometimes, long-standing pelvic infections also interfere with the ability to conceive. These are frequently seen in those with sexually transmitted diseases, such as gonorrhea and Chlamydia.

In all such situations, it is recommended to treat the infection, and in case of irreparable damage, look for alternative options. Chronic genital infections cause scarring of the genital tract that makes it difficult for sperm to reach the egg (and for zygote- combination of egg and sperm) to reach the uterus for implantation that serves as a cozy environment for the development of your baby.

There are a number of other causes also that include systemic diseases; defects of the uterus, cervix or other part of genital tract; autoimmune diseases, such as anti-phospholipids antibody syndrome (APLA); and other local or systemic defects.

Common Causes of Infertility in Men:

In men, the most common cause is having issues with the quality sperm count. Men who are exposed to toxins, chemicals and genital infections tend to have issues with spermatogenesis that leads to:

  • Low Sperm Count in Semen

A normal semen sample must contain at least 15 to 20 million sperm per ml. Generally, each semen ejaculate is approximately two to five ml. The cause of male infertility is mostly abnormal amounts of semen (too much or too little semen) or abnormal sperm count.

  • Morphologically Abnormal Sperms:

Sperm health and morphology are very important determinants of fertility assessment. Sperm are released in vaginal fourchette and have to travel all the way up to the fallopian tubes.

It is really important that most of the sperm in semen/ejaculate are not only healthy but are also mobile and have a great energy supply that lasts until the sperm get to the fallopian tubes. For optimal male fertility, a semen sample must contain:

  • At least 50 percent motile sperms (that show forward motion even after an hour of the ejaculation).
  • At least 30 percent sperm that are morphologically/physically normal in shape.
  • Normal pH (7.0 to 8.0) of semen that have no signs of infection, such as bacteria and other microorganisms.

Any man who is exposed to noxious stimuli, such as cigarette smoking, alcohol consumption, drugs and certain occupational hazards, such as radiation, chemicals, benzene and other chemicals that can affect the health of sperms or affect libido leading to decreased ability to perform intercourse can also lead to infertility. Exposure to chemicals and radiation affect the ability of sperm to handle environmental stress.

Surprisingly, a lot of couples have no recognized medical condition but are still not able to conceive readily. In all such cases, it is important to adopt a few healthy tips before looking for alternative treatment options.
