welcome to HCM,
Thanks for yr query, first I tell you that BTM has on direct role in abortion or infertility
.but prior to plan for a child you have to tested your wife for thalessimia to avoid the future baby with thallassemia major.If she has not thallessimia then you consult Gynecologist for infertility and recurrent missed abortion
,causes of missed abortion are to many may be the TORCH infection
or may be due aneamia,avitaminosis
,any pathology in genital organs or may be due to hormonal
imbalances..it is required to many blood profile.ultasound study and physical examination by gynecologist.
