- Male Infertility
- Causes
- Physical abnormalities of the male reproductive tract, such as obstruction or impaired sperm production.
- Abnormalities of the sperm itself.
- Assessed through: Semen analysis
- A normal assessment should show:
- Sperm count of more than 20 million sperm per millimetre.
- 50% of sperm actively moving.
- 30% of the sperm must have normal shape.
- Sperm should survive for 24-48 hours
- A normal assessment should show:
- Defective Sperm Production
- May be associated with infections, surgery, or excessive drinking.
- Certain drugs, such as radiation and radiotherapy can also affect the production of sperm.
- Azoospermia
- Refers to the absence of sperm in the ejaculate.
- This may be due to: Obstruction in the vas deferens, the vas deferens being missing, a hormonal problem stopping sperm from being reduced.
- Antibodies
- May attach to sperm and impair their mobility of their ability to penetrate and fertilise an egg.
- Impotence ('Erectile Dysfunction')
- The inability of a man to achieve or maintain an erection sufficient for his sexual needs or the needs of his partner.
- Most men experience dysfunction at some point in their lives, usually by age 40.
- But, it has now been established that impotence affects younger men too.
- The cause is often circulation-related, resulting from prescription drug use, smoking, drinking, or diabetes.
- Many men suffer a combination of physical and psychological reasons.
- It is very easy for a man with impotence to become stressed and depressed about his situation and this makes things worse.
