<s>[INST] Hi I am a 41 year old male and I noticed that I ejaculate in small quantity and it's kind of thick and lumpy. I have been trying toget my wife pregnant for some time now but it's not working out. Should I be worried about my sperm or do you advise on having a sperm test done ? [/INST] Hi,nothing to worry about quantity and viscosity of semen.But as there is problem for conceiving, go for semen examination for any abnormal count.Ok and take care. </s>
