I'm assuming you're male. To my knowledge, other than passing on hereditary diseases, a male's physical state can't affect the health of a baby. I'm more concerned about YOUR health and whether or not you can even father a child. The irony with taking testosterone cypionate is that it improves fertility in those that have low testosterone levels but DECREASES fertility in those who have normal testosterone levels and take the drug. Use of this drug can cause testicular atrophy (shrinkage of the testicles), azoospermia (no measurable amount of sperm in semen), oligospermia (low semen volume), decreased sperm motility (the ability of the sperm to reach the egg), and impotence. For some, discontinued use of the drug enables their bodies to return to normal but for others the effects are permanent.
One other thing, a sudden halt in the use of this drug can cause bad side effects. You may want to consult a doctor.
If you are a female, this drug can cause birth defects as well as a number of other problems.
