Write a note fertilization and embryo development after ivf
We plan to culture round spermatids to the elongated stage in vitro and use as the success rates of clinical pregnancy are higher with ELSI as discussed earlier.

However, there are low pregnancy rates following ICSI using round spermatids from men with no elongated spermatids or spermatozoa in their testes.
