Hi XXXXXXX
Thanks for writing in to us.
I understand your dilemma with the amount of information and opinions including those given by doctors regarding penis size and it being controlled by genetic factors.
At first I would like to re confirm that your penis size of 2.2 inches when flaccid and 5.1 inches on erection is normal for an Indian male to satisfy his female partner.
Regarding erect penis measurements, following documented studies have been done with findings as follows:
1. In a study of eighty healthy males published in the September 1996 Journal of Urology an average erect penis length of 12.9 cm (5.1 in) was measured. The purpose of the study was to “provide guidelines of penile length and circumference to assist in counseling patients considering penile augmentation.” Erection was pharmacologically induced in 80 physically normal American men (varying ethnicity, average age 54). It was concluded: “Neither patient age nor size of the flaccid penis accurately predicted erectile length.”
2. A study published in the December 2000 International Journal of
Impotence Research found that average erect penis length in 50 Jewish Caucasian males was 13.6 cm (5.4 in) (measured by staff). Quote: "The aim of this prospective study was to identify clinical and engineering parameters of the flaccid penis for prediction of penile size during erection." Erection was pharmacologically induced in 50 Jewish Caucasian patients who had been evaluated for
erectile dysfunction (average age 47±14y). Patients with penis abnormalities or whose ED could be attributed to more than one psychological origin were omitted from the study.
3. A review published in the 2007 issue of BJU International showed the average erect penis length to be 14–16 cm (5.5–6.3 in) and girth to be 12–13 cm (4.7–5.1 in). The paper compared results of twelve studies conducted on different populations in several countries. Various methods of measurements were included in the review.
4. An Italian study of about 3,300 men concluded that stretched length was measured on average to about 12.5 centimetres (4.9 in). In addition, they also checked for correlations in a random subset of the sample consisting of 325 men. They found a few statistically significant Spearman's correlations: between flaccid length and height of 0.208, –0.140 with weight, and –0.238 with BMI, flaccid circumference and height 0.156, stretched length and height 0.221, weight –0.136, BMI –0.169. They also reported a few non-significant correlations.
Talking about effect of genetics on penis size, there are certain genes like homeobox (Hox a and d) genes which may have a role in regulating penis size. There is also In humans, the AR gene located on the
X chromosome at Xq11-12 which may determine the penis size. Deficiency of pituitary
growth hormone and/or gonadotropins, mild degrees of androgen insensitivity can cause small penis size in males and is treated with can be addressed with growth hormone or
testosterone treatment in early childhood.
So you can see that there is influence of genetics on penis size among other factors like the environment.
Cosmetic surgery is a commercial application of medical science for aesthetic purposes and beauty. It is more for the appearance and is to address the psychology of patients.

Hope your query is answered.
Do write back if you have any doubts.
Wishing you good health.
