Once the cancer has been overcome and the quality of the semen is low, would conventional IVF be recommended or would it be passed directly to an ICSI?

Once cancer has been treated, the male may be fertile. If this is not the case, he may resort to using the sperm he had frozen before his treatment. In these cases, since the semen is very valuable because of its scarcity (only one or two frozen samples), ICSI is used directly, since gestation can be achieved with a single spermatozoon. Thus, if more children were desired, there would still be a frozen sample.
