The Israeli parliament recently passed a highly anticipated bill allowing spouses or parents of deceased soldiers to extract and freeze their sperm within 72 hours after death for future use in IVF procedures to continue the family line. The passage of this bill has sparked widespread discussions in society and drawn attention to the technology of sperm cryopreservation.

Recent studies have shown that frozen sperm is as effective as "fresh" sperm in intrauterine insemination (IUI) procedures. Researchers from Massachusetts General Hospital and Harvard Medical School conducted a large-scale study and found that frozen sperm is just as effective as fresh sperm in intrauterine insemination procedures. Dr. Panayiotidis, the lead researcher of the study, attributes this finding to the continuous improvement of sperm freezing technology, which has significantly improved the effectiveness of frozen sperm in intrauterine insemination procedures compared to previous studies.

Although the quality of frozen sperm may slightly decrease during the freezing and thawing process, it does not significantly affect clinical outcomes. Researchers analyzed 5,335 cycles of intrauterine insemination from 2004 to 2021 and found that the clinical pregnancy rates were similar between the use of frozen sperm and fresh sperm, with slightly longer pregnancy times in the frozen sperm group. Additionally, the study found no additional risk of miscarriage in the frozen sperm group.

For patients with poor sperm quality, using intracytoplasmic sperm injection (ICSI) for IVF may be a better option. Furthermore, in countries such as the United States, Mexico, and Cambodia, the use of third-generation IVF-PGT technology allows for genetic diagnosis of embryos before implantation, screening out healthy embryos and ensuring the baby's health at the genetic level.

Overall, the effectiveness of frozen sperm is comparable to that of fresh sperm in the IVF process, which will bring confidence and hope to more people who wish to use sperm cryopreservation technology.
