Thing is, sperm counts in men are diminishing all over the world, including macho/conservative/heterosexual cultures like India. Kindness, and respect for women in men are not the problem. It's a myth that either sex dominates each other in the heterosexual sexual act. Both sexes like domination and submission. 
Also, men have male and female hormones and balance is what is important for health. Low estradiol and low testosterone are predictors of mortality in aging men. The testosterone drop in men who have children has to do with getting less sleep, increased stress, poorer diet, and less exercise due to lifestyle changes. There's probably multiple factors at work with testosterone decline in men.
