The main factors that affect the vagina and interrupts in the sexual intercourse are as follows:
Pelvic Inflammatory Disease is the most common cause of infertility. Any infection or damage to the sexual or reproductive organs such as ovaries, fallopian tube, cervix or uterus often results in infertility.
Endometriosis is a disease that affects the uterine lining implanted in the vagina, fallopian tube, ovaries or pelvis. This damage to the uterine lining results in the formation of cysts which eventually blocks the passage of egg.
Infertility can also be caused by any improper reproductive cycle or impaired functions of the female reproductive hormones. Any infection or problems associated with the ovaries inhibit the release of egg.
Many women also suffer from some kind of immune disorder. Women may develop immune cells that fail to learn the difference between toxic invader and man's sperms. These antibodies often attack the sperms and normal reproductive cells in her body. This also is a major factor contributing to infertility.
