if some one (already a parent of a very healthy baby) is now easily conceiving each time but ends as a Missed Abortion within the 1st trimester due 2 the lack of cardiac flicker (baby's heart)...being already a parent of almost 4 yr old baby, nothing seems abnormal in both the spouses, apparently her gyno fails 2 xplain the xact cause behind this condition... wht cud be the possible reasons? is this an issue of some sort of male or female infertility? shd v here "question the male fertility too"? or itz only "the female partner Responsible" 4 all these missed abortions????
