THE NUMBER OF OUR ROSI PREGNANCIES IS INCREASING

THE NUMBER OF OUR ROSI PREGNANCIES IS INCREASING

In nearly half of the azoospermia cases, the tube baby (IVF/ICSI) cannot be performed because the lack of fully developed sperm cells in the testis and so the procedure is canceled. Here, the new ROSI technique was a hope for these cases. The new ROSI technique described by Tanaka also allowed spermatids with insufficient tail development to be used in IVF. Our own experience also showed that healthy pregnancies can be achieved with this method in nonobstructive azoospermia cases. We can foresee that this number will increase even more as our ongoing pregnancies are delivered.

The important factors here are; choosing suitable men for ROSI, before passing to the TESE demonstration of sperm cells that have reached a certain genetic maturity stage in the testicles, proper preparation of the man for 3-6 months, very meticulously performed TESE surgery and showing that the genetics of the cells collected during TESE are not abnormal and they are in haploid structure.

The new ROSI technique can be applied to germ cells in different developmental stages. They may be round spermatid cells that have no tail formation, as well as elongating spermatids that have started but not fully matured tail development.
