I recently observed that with proper exercise and proper daily water intake - I have a the usual sperm thickness and color. However on days when I'm smoking cigarettes, no exercise, low water intake the color changes to slightly off-white or say very light yellowish. In general, this makes sense. However I've been consuming 1mg finasteride for the last 3 years - and I've had no issues with my performance but I see low quantity of the ejaculation. Sometimes it can be watery - but when I have proper or elongated stimulation I get the regular thick ejaculation. All in all I'm a little stressed about pregnancy now. 1- Will the quantity affect our chances of getting pregnant? 2- Should I stop Finastride and the quantity may go back? Or in general it has any affects on pregnancy? My wife doesn't touch the tablets. 3- Does Varicocele on left side is causing this issue on the sperm quantity? I've had it since I was 20-21yr old - maybe even younger just not sure about the age.
