could you explain any challenge that could be encountered by a man who is AA+ who marry a woman who is O-. when a woman finish her period and does not ovulate what could be the problem?
A man of AA+ with women with O- can lead to RH incompatibility which may affect the second child and onward and may lead to fetus death in uterus which occur due to sensitization during the delivery of first child and antibody formation which then damages the future pregnancy, but this can be prevented by adequate administration of anti D immunoglobulin during first delivery which prevent antibody formation. When a woman do not ovulate after her period the cause can be hormonal imbalance due to inappropriate gonadotropin release, low LSH level or even ovarian failure.
