It sounds so funny though, but it caused a serious tension between couple in my locality which my attention was drawn to make peace.

While trying to know what actually happened, the man rebuffed me, but the wife exclaimed, can you imagine? Ears opened, my hubby has refused to buy routine drugs that was asked to be taking as a pregnant mother.
But she paused, I then asked why? She took a breath, while the man was looking at her, she said asked him.
To cut short the story, the woman narrated the reason that, the man believed that his sperm is blood, thereby trying to make love with her always to boost the woman's health in place of routine drugs.

Honestly, I managed to hold back my laughter as not to anger her, but I could not believed what I heard.
I have to face the man and asked if he said that, he responded by asking me if it is true.

Not a medical professional though, but I told him that it is true. That the can also do well to visit their Doctor for counselling and advice.

Since then, I have imagining, in this modern world, people could still think and reason this way.
