A high-risk pregnancy is one of greater risk to the mother or her fetus than an uncomplicated pregnancy. Pregnancy places additional physical and emotional stress on a woman’s body. Health problems that occur before a woman becomes pregnant or during pregnancy may also increase the likelihood of a high-risk pregnancy.
ICSI also can be performed in azoospermic men (where semen sample contains no sperms).
In such cases the testis are producing sperms but due to block in the tubules or in the path through which the sperms come out from the testis, the sperms produced in the testis cannot come out.
