Three Factors Affecting Men Infertility
There are three main causes for problems with sperm: production, function and delivery.
Sperm Abnormality:
Sperm can have an abnormal shape and movement that would create
problems for fertilization. The shape and structure of a sperm is
referred to as "sperm morphology". Obviously if the sperm have mobility
problems they will have difficulty even reaching the egg. Any abnormal
shape of the
sperm also contributes to difficulty with mobility.
The absence of sperm in the testicles is extremely rare but it does
occur and is a cause for infertility. Couples who are diagnosed with
this as their cause for
infertility have very little options, other than
sperm donor or adoption.
Normally a man will produce approximately 20 million sperm per
milliliter of semen. If the test reveals that a man has 10 million or
fewer, that would be classified as having a low sperm count. There can
be many reasons for a low sperm count. When a man has less than 5
million sperm per milliliter of semen, than genetic causes are
considered.
| Increase Semen Kit: |
| Increases the quality and quantity of semen. Increases the sperm count, sperm motility and healthy sperm count. |
| Complete Vajikarana Therapy: |
| complete therapy to increase hardness, duration of hard erection, sperm count, sperm motility and sperm volume. It helps in premature ejaculation |
Reasons for low sperm count:
Diseases like Varicocele, which prevents the testicle from cooling. When temperature is too high sperm cannot survive. Cryptorchidism or an undescended testicle occurs when one or both of the male testicles fail to descend from the abdomen into the scrotum during fetal development. This causes problems in sperm production because the sperm are exposed to higher body temperature in the abdomen.
Other causes of low sperm count are: disorders of the testicles or abnormal hypothalamus or pituitary glands. There is a disorder of the sex chromosomes that can cause abnormal development of the testicles which results in a lower than normal level of testosterone.
Males who contract certain infections can also have an adverse affect on their sperm count. Infections such as some sexually transmitted diseases like chlamydia or gonorrhea. Scarring happens during the course of these diseases that can cause block the passage of sperm. When males come down with the disease mumps past childhood, they can experience an inflammation of their testicles that may result in lower sperm counts or impaired sperm. Should the man's prostate, urethra or epididymis become inflamed this can cause motility problems with his sperm.
Delivery Problems:
Delivery problems are classified as when the man has difficulty
getting the sperm from his penis into the woman's vagina.
Causes can be:
- Sexual in nature
- Problems with the ejaculation
- A possible blockage in the epididymis or the ejaculatory ducts
- Absense of the fluid part of the semen
- A misplaced urinary opening, also known as the "hypospadias"
- Anti-sperm antibodies (usually present in cases of men undergoing a reversal of a vasectomy.
- Cystic fibrosis - men with this disease may not have a vasa deferentia or it may be blocked.
Health and Lifestyle Causes:
- Emotional stress
- Deficiencies in Vitamin C, Selenium, zinc or folate
- Obesity
- Cancer and the treatment for this disease
- Alcohol and drugs
- Severe injury or having major surgery to the male reproductive organ
Other diseases that can contribute to male infertility are:
- Anemia
- Diabetes
- Cushing's syndrome
- Having a heart attack
- HIV/AIDS
- Kidney or Liver failure
Just like in women there is a decline in fertility with men after age 35. Men however, have a more gradual decline in fertility than women do.
