Is penis related to pregnancy?
Size and pleasure
Despite all the myth and misinformation, it is not the size that matters but what you do with its and all other body parts when it comes to satisfying a woman. I know women who have told me that men with very tiny organs gave them great orgasms and men with huge ones did not know what to do with it. Generally speaking even the smallest size can please a woman. So go out there and do what you can with it and your hands, mouth and tongue and stop fretting about the size, the myth for which has been created by quacks, crooks, and spammers to sell you snake oil.
Size and pregnancy
The same is true for making babies. If the woman is fertile and healthy and you can engage in normal lovemaking, she should get pregnant. Having said that, if you have been trying to make your wife pregnant for 12 months and have not succeeded, then it is time to meet with a fertility specialist. It may have nothing to do with your organ size but there are so many other things inside a woman's body that could not be working normally. For men, it is not the size that is important for pregnancy, but sperm count, sperm quality and motility that are important and these can be checked with a simple test.
