No scientific research supports the use of any nonsurgical method to enlarge the penis .FDA the government agency that regulates medications and medical devices has never approved any medications or devices for enlarging a penis .You should not waste your money on any such products as there will be no result .Also in some cases there can be harmful side effects of these products .No reputable medical society endorses penis surgery for purely cosmetic reasons .The surgery can be risky and dangerous.
Regarding sperm volume there are various measures which increase the sperm count -
Not having any sexual activity for 1-2 weeks will help to increase the semen volume .
Masturbate less .
Also some natural supplements are being used like Withania somnifera,speman.
Otherwise you need hormonal checkup to know various male hormonal levels. Exact diagnosis can only be made after physical examination & tests.
So I advice you to make an appointment with your urologist doctor to know the exact cause & treat accordingly.
I hope this helps.
I really don't know if a larger penis is what I want. I think I am average but don't know. I'm 5.5 inches. My sperm volume is what bothers me most. I master ate 2 times a day. I have to because if I don't I keep an erection. I just don't produce much sperm.
Yes the size is normal.( 5.1–5.9 in)
So you don't need any medication for penis enlargement.
Regarding sperm production keep your self hydrated and you can try some natural supplement described above.
