Is Using L-Arginine Gel Safe While Planning For A Baby?

Hi there, I got married recently, we started planning for a baby. Since i am not naturally lubricating the sex process became tough to me. Me and my hubby consulted a gynecologist for the same. She prescribed us L-Arginine Gel. Is it safe to use when we are planning for a baby? Will the sperms lose its life coz of tis gel? Pls advice.
