Causes of Infertility in Women

There may be one or more of the following factors causing infertility in a woman:

· Abnormal Fallopian Tubes - Any abnormality in the fallopian tubes, no matter how insignificant it may seem, may lead to unexplained infertility. Fallopian tubes contain minute structures like the fimbria and the cilia that help to sweep the egg cells down into the uterus. Any problem prevent the eggs from being fertilized.

· Abnormal Eggs – Since ovaries are equipped with thousands of eggs, it is unlikely that not one of them would be suitable for fertilization unless there is abnormality in the size or shape of the eggs or in the chromosomes they contain.

· Weak Sperm – Unhealthy or abnormal sperm can also affect pregnancy outcome. In order to become fertilized, sperm must be able to break through the outer shell of the egg. When even seemingly healthy-looking sperm are not strong enough to break through the egg to fertilized it, no embryo will be created.

· Luteinised Unruptured Follicle (LUF) Syndrome - During the maturation process, eggs are stored inside a tiny membrane called a follicle. This follicle will release an egg through ovulation. After that egg has moved into the fallopian tubes the membrane leftover is referred to as the corpus luteum. LUF is caused when the follicles become corpus luteum before releasing the egg – in effect, trapping it inside. Thus, ovulation is blocked.

· Abnormal Luteal Phase – Luteal phase is the new phase of the menstrual cycle which starts when the egg has been released from the ovaries. It is during this phase that the corpus luteum begins to produce progesterone – the hormone responsible for stimulating the uterus to prepare the endometrial lining for implantation. If, however, the progesterone levels rise too quickly or too slowly, or if the hormone was not produced for a long enough period, the endometrium will not be properly prepared for implantation.

· Immune System Problems - The immune system is designed to protect the body from any invading organisms. However, it can sometimes become confused, and start to attack healthy cells. When a woman’s immune systems begins to attack her own eggs or a man’s immune system causes the sperm to stick together, pregnancy will not happen.

· Emotional Factors – The reproductive system is controlled by the brain. That is why any emotional problem affecting the psychological well-being of the couples can cause infertility.
