we got married 4 years ago and have no kids. My wife conceived 2times.but both leads to miscarriage after 4 wks as the baby was not growing.then I was diagnosed with vericocile vein and had undergone surgery last month. After that my doctor gave me levocarnitine tablets USPS carnisure 500 for 6 months to have twice a day.will this help me to increase sperm count and motility?
