My boyfriend is a body builder and takes testosterone booster can this help us conceive its a natural booster?

No!: The exact opposite, supplemental testosterone and androgenic steroid supplements will reduce or eliminate his sperm altogether. It'll be 3 months after he stops before he'll bounce back, there are good reasons that steroids for bodybuilding are mostly banned.

The sad truth: These boosters are exempt from FDA rules because they are "supplements". They do not have to contain what they say or do what they promise. Many do boost pre-testosterone chemicals that cause acne, shrink the testis and give the weightlifter something to think works (placebo effect). Don't expect this to help.
