Like in males, malfunction of any part in the female reproductive system can also be a cause for infertility.
It is caused when a woman fails to produce eggs regularly. This may be due to an imbalance in the hormone production. Due to problems in hypothalamus and pituitary (parts of the brain) FSH and LH are not secreted in the right proportion and at the desired time. An example of such a condition is the Polycystic Ovarian Syndrome (PCOS).
Due to failure in producing FSH and LH, the ovarian follicles are not stimulated adequately to release the egg. This is called Hypothalamus Pituitary Failure.
Hence, the ovaries fail to produce eggs. This is called Ovarian Failure.
Certain hormonal disorders like less secretion of thyroid hormones and excess prolactin hormone also prevent release of eggs from the ovaries. Sometimes eggs are not produced or released due to excessive stress, strain, weight loss or even bad diet.
If the fallopian tubes are blocked, the egg and the sperms cannot meet. The fallopian tube blockage can be due to
The sperm has to pass from the vagina through the cervix to the uterus and ultimately to the fallopian tubes to meet the egg. The cervical canal is very narrow and is filled up with mucous through which the sperm has to pass. Therefore, problems in the structure of the cervix or type and texture of the mucous can prevent the sperms to pass through it. This may happen if
Infertility also occurs if the endometrium is unprepared for embedding the fertilized egg. This may happen if
