Very often, a perfectly fertile man may not be able to ejaculate. Since he can’t make love properly, he can’t make babies some men can’t even have an erection (impotence) and some cannot achieve an erection sufficient for intravaginal penetration or ejaculation in the vagina.
An older theory held that 80% of impotency problems, which are very common, were rooted in psychological inhibition & fears which could respond to sex therapy & counseling. However, modern research has lowered this figure & estimates that up to 50% are due to physical causes ranging from inadequate blood flow to the penis, diabetes, neuralgic defects & hormonal problems. Further recent clinical studies show that up to 80% of erectile dysfunction cases are due to physical reasons.
Occupational hazards
certain occupational hazards affect fertility by upsetting the hormonal balance, thereby suppressing sperm production, and resulting impotence. Working in places of excessive heat and with dangerous chemicals that have an adverse impact on sexual functions & fertility which include heavy metals, like lead, nickel & mercury; insecticides; petrochemicals; pesticides; benzene; xylene; anesthetic gases & X-rays.
Duct blocking
If the passage (reproductive tract) between the penis and tests is blocked, there will be no sperm in the semen. Blockages can be caused by infection (due to gonorrhoea, chlamydia, filariasis or TB) or by surgery done earlier to repair hernias or hydroceles. This situation also creates erectile dysfunction. Psychological causes of erectile dysfunction or impotence include –
Stress & anxiety from work or home
Worry about poor sexual performance
Unresolved sexual orientation
