Can varicoceles vein in my testicle affecting my testosterone?

Not likely . . .: Varicoceles might affect sperm production by warming up testes but they won't affect testosterone production. If your pituitary isn't sending out enough lh, your t level might be low. Or if you've had trauma, injury (torsion) or infection (mumps orchitis) that damaged testes, your t level could then be lower than in past. Check w/your family doc to determine cause prior to starting therapy.
