Hi The chances of fertilisation by natural methods are low when the sperm count in 3 millions. Has your husband been fully evaluated by an andrologist/urologist. He will need to be clinically examined, have blood tests to check hormone profile and might need to have an ultrasound of the testicles. If you are getting closer to age 35 then my best advice would be contact an infertility specialist now rather later as the chance of fertilisation by artificial methods fall rapidly once females age gets past 35 yrs. Meanwhile your husband might want to take multivitamin supplements, avoid tight under clothing and bathe in cold or luke warm water than hot water.
