In some cases, it may not be possible to explain the cause. In normal conditions, the tubes behave like a fishing rod, picking up the ovum that has been released during ovulation, transporting the sperm towards the ovum and guiding the fertilised egg to the uterus.
Partial damage to the tubes due to an adhesion, or complete damage due to tubal obstruction, will prevent this transport and as a result fertilisation will not take teratzoospermia. Tubal damage can occur due to:. Tubo-peritoneal factor is also associated with ectopic pregnancy, which is when the embryo does not reach the uterine cavity due to alterations in the diameter and causa interior of the tube which prevents it from being transported correctly.
Its name derives from the word endometrium, which is the tissue that lines the inside of the uterus and which is lost each month during menstruation.
Endometriosis consists of the presence of this tissue in places other than its usual location, which is inside the uterus. It is most frequently found in the ovaries, Fallopian tubes, the ligaments which support the uterus, and the lining of the pelvic or abdominal cavity.
This tissue is sensitive to the hormonal changes that occur during menstruation, giving rise to teratozooslermia symptoms that this causes.
Although some patients may not have any symptoms, the most common ones are pain and infertility. Pain may only occur during tegatozoospermia, but there can also be gastrointestinal and urinary symptoms, if these implants of endometrial tissue invade other structures such as the intestine, the bladder or the rectum.
Infertility related to endometriosis can arise from the changes which occur in the pelvic anatomy of these patients during their cauxas cycles. It can cause obstruction of the tubes or the formation of endometrioma ovarian cysts, which occasionally require surgery, with the attendant loss of ovarian tissue and decrease in fertility.

IVF is an appropriate treatment for sterility associated with endometriosis when other techniques have failed. Pregnancy will represent an excellent temporary treatment for improving the endometriosis.

Among the determining factors for this situation are: The origin of this hormonal disorder may be in the hypothalamus, pituitary gland, or in the ovary itself.
To study male fertility, an analysis is carried out which tests the number, activity and shape of the spermatozoa. With lower quantities the chance of pregnancy falls substantially. The main causes of this may be found in the glands in the brain the pituitary gland and the hypothalamus which produce the hormones regulating the formation of spermatozoa, in genetic disorders Klinefelter syndrome, alteration of the genes on the Y-chromosome that regulate the formation of spermatozoa, etc.
Spermatozoa can show anomalies in their motility astenozoospermiashape teratozoospermia or vitality necrozoospermia.
