Homeopathy may not help as good as the allopathic medications. Get her hormones under control and eat a well balanced diet, avoid smoking and alcohol to increase your sperm counts.. Once everything is fine, go ahead with the test tube baby thing..Abortion is known to cause infertility problems..educate other couples not to abort the first pregnancy to avoid later complications such that you are facing.. Babies are God's gift, if you refuse it, and kill it, God will not find you worthy to get blessed again.
