I wish to conceive a baby boy what precaution i need to take.

Wants a boy: The ratio of males to females is appro. 51/49% per pregnancy. The only way to increase your odds to perform gender selection please see my web site www.genderselection.com.

None short of lab: There are several "methods"proposed by a variety of sources that include timing or rituals but none work.There is no vaccine or shot that helps. If you want to spend big at a fertility center they can test & select a male embryo for implantation. This has no guarantee of success.
