Welcome To HealthcareMagic forum,
Rahul ,if you are having itching over the genital and it is more in the night ,then it is not a fungal infection
,instead it is SCABIES
.Scabies causes more itching in night time only and it effects genitals( esp penis ,as you have mentioned). Fungal infection causes itching through out the day and it effects mainly the groins .If it is so ,then kindly reply me ,so that I can suggest you a remedy.
