Thanks for your query.Your husband has Bil mild to moderate Hydrocele
.You have not mentioned any thing as regards sperm anslysis for eg sperm count
, sperm motility
etc.If sperm count is less than normal you have to take some measures like doing some moderate exercise daily,avoid alcohol,smoking ,and take anti oxydents medication and Tab Fertyl once daily for three months Repeat your semen analysis
after three months .Though surgery for correcting varicocele
does not guaranty 100% positive results you have to undergo it as there are 50% chances of improving the sperm count after the surgery which is minor in nature.
