Causes of Infertility In alphabets Order - Letter E to F A. Letter E

33. Ejaculation disorders
a) Premature ejaculation
Premature ejaculation is defined as persistent or recurrent ejaculation with minimum stimulation before, during or shortly after vagina penetration against the person wish. Most men with premature ejaculation have a weak yang or yi kidney leading to lower quality and quantity sperm count resulting in increasing the risk of infertility.

b) Delayed ejaculation
Delayed ejaculation is a medical condition in which a male is unable to ejaculate, either during intercourse or with manual stimulation in the presence of a partner. It is caused by psychological and physical problem including less interest in sex with his partner, sex is sinful, medication and nerve damage to the spinal cord.

c) Retrograde ejaculation
retrograde ejaculation is caused abnormal function of the sphincter muscle at the base of the bladder. During the ejaculation, the sperm travel backward into the bladder instead to the open of the penis head causing infection to the reproductive organs, including the bladder thereby, no seminal fluid emerges from the penis head.
d) Anejaculation
Anejaculation is defined as inability to ejaculate caused by psychological or physical problem including Sexual inhibition, nervous system malfunction or medication.

32. Emotion stress
Since emotion stress effects the hormones in our body. Negative stress increase the risk of over production of certain hormones which interfere with normal function of menstrual cycle for women and lower the sperm count for men resulting in lessening the chance of fertility. Pregnant women with constant stress may increase the risk of miscarriage.

33. Endometrial hyperplasia
Endometrial hyperplasia is defined as overgrowth or thickening of the uterus lining as resulting of high levels of estrogen and insufficient levels by of progesterone leading miss ovulation and infertility.

34. Endometriosis
Endometriosis is defined as cells of endometrium grow somewhere else other than in the endometrium. Normally, endoemtriosis not travel far but around the uterus region. It interferes with the ovulation and embryo implantation leading to infertility and miscarriage.

35. Endometritis
Endometritis is defined as infection or inflammation of the uterine lining caused by pelvic infection or sexual transmitting diseases leading to miscarriage for pregnant women.

36. Xanoestrogen
Xanoestrogen is also known as environment estrogen acts as estrogen. it can remain in the body for a long time and blocking and interfering with body's natural normal functions leading to many disorders including low sperm count, abnormal sperm production and movement in men and abnormal overgrowth of vagina lining, premature breast growth in women and infertility in both.

37. Environment factors
Expose yourself in certain chemicla encironment may interfere the body hormone production leading to reproductive abnormal function resulting in increasing the risk of birth defect, stillborn, infertility and miscarriage.

38. Epididymal obstruction
Epididymis is a tiny tube which attaches to the testicle. Epididymals obstruction is defined as the blockage of the passage of sperm to penis leading to low sperm count and increases the risk of infertility.

39. Epididymitis
Epididymitis is defined as inflammation of epididumis caused by bacteria, sexual transmitting duseases and urinary tract infection leading to infertility if infection spread to testicles.

40. Epipadas
Epipadas is a type of abnormal formation of the penis at birth in which the urethra ends in an opening on the upper aspect of the penis. Men with epipadas have normal sperm production, but the ejaculating sperm can not deposit to the cervix interfering with sexual erection and leading to infertility.

41. Erectile dysfunction
Erectile dysfunction also known as impotence, is defined as the repeated or persistent inability to get or keep an erection firm enough for sexual intercourse over period of at least 3 months. Its is caused by not enough blood flowing in and fill the spaces of the veins and arteries and hormone imbalance as resulting of psychological factors, heart diseases, diabetes, kidney disease, chronic alcoholism, etc. leading to infertility.

42. Exercise
While rigid exercise reduces the chance of fertility because it interferes with the production of sperm and egg as well as decreasing the brain message to test and ovaries, moderate exercise improve it. Rigid exercise not only decrease the blood flow to the reproductive organs, it also signals the false message to the nervous system to divert all energy to organs other than reproductive system disrupting the flow of qi in the abdomen leading to hormone imbalance and stop ovulation resulting in increasing the risk of infertility.

43. Fibroids
Fibroids are benign tumours that grow in, on or outside of the wall of the uterus. If it grows big enough, it may interfere with the implantation of embryo in the uterus leading to premature delivery and miscarriage and increasing the risk of infertility if they grow near the opening of both Fallopian tubes and distort the shape of uterine cavity.
