Thanking you [/INST] Good day, and thank you for being with Chat Doctor ! First since you have a scrotal pain you need to have a scrotal ultrasound with Doppler to check for varicocele. This is the most common cause of infertility in men and if treated this would improve your semen parameters. Eating right and exercising will also improve your semen parameters.  I hope I have succeeded in providing the information you were looking for. Please feel free to write back to me for any further clarifications at: http://www.ChatDoctor .com/doctors/ Chat Doctor.  Best wishes. </s>
