Hello,
I have gone through your query and understood the concern. The cause of the repeated abortions must be known through a complete evaluation by a specialist. There can be several causes for first trimester abortions that include genetic defects, trauma, infections, medications etc. If a histopathological evaluation was done of the products of conception, that would give much insight into the possible causes before another pregnancy is contemplated. Toxoplasma is an infection which once contracted gives lifetime immunity and is not likely to affect future pregnancies. The titres are important in this aspect. Hope your query has been clarified. Take care.
