Female infertility
Infertility in the female is related to many factors. Mainly, the faulty production of ova, or the interference with their union with spermatozoa.
Failure to ovulate, or produce an ovum (egg), is a common cause of female infertility and usually results from hormonal imbalances, particularly the stimulation or suppression of the ovaries by other glands such as the pituitary, thyroid or adrenals.
The result can be an inadequate production of female hormones, and a consequence disruption of normal ovulation.
Blockages of or an obstruction within the fallopian tubes in which an ovum is fertilized by a sperm is also a common cause of infertility in the female. The tubes may become blocked owing to endometriosis or inflammations.
Vaginal causes are usually uncommon, but abnormalities of the cervix are among the most important causes obstructing the passage of sperm.
The sperm enters the uterus through the cervix and, from the uterus, move into a uterine or fallopian tube, where fertilization of an ovum takes place. During the few days prior to ovulation, the cervix normally secretes thin, warey mucus that is beneficial to sperm survival and migration.
Various factors, such as infection or estrogen deficiency, may decrease the quality of the mucus. Or may even be lethal to sperm because of hormonal abnormalities or unbalanced acid-alkaline ratios
