Dear Doctor, I m Pradeepa from Tamilnadu, India For about 1+ year we are planning for a child, My husband has Adrenoleukodystrophy(ALD/AMN) problems, his semen has 15% Motality and low semen count and many Dead sperms . we tried In vitro fertilisation 2 times, but the results are negative. What may be the reasons? But the Embryos are not bad. Even after freezing for 2 months the Embryos are good and the growth is fine. May i know Because of the semen quality/ defective semen or will i have any problems in Uterus, But the tests are normal? The Embryologists saying, defective semen may cause the negative results Kindly guide us on the same, kindly give us some medication for over coming the defective semen Thank you Doctor
