The International Swimming Federation (FINA) has banned transgender athletes from competing in women's swimming events if they have experienced any part of male puberty. The decision was made following a recommendation from a FINA working group, which was tasked with reviewing the issue of transgender participation in swimming.

The working group's report found that "there is a clear difference in performance between male and female swimmers at all levels of competition." The report also found that "there is no reliable or consistent method to assess the impact of testosterone suppression on transgender women's athletic performance."

Based on these findings, FINA decided to create a new "open competition" category for transgender athletes. This category will allow transgender athletes to compete in FINA-sanctioned events, but they will not be eligible to compete in women's events.

The FINA decision has been met with mixed reactions. Some people have welcomed the decision, arguing that it is necessary to protect the fairness of women's swimming. Others have criticized the decision, arguing that it is discriminatory and that it excludes transgender women from participating in the sport.

The FINA decision is likely to be challenged in court. It is also likely to have a significant impact on the future of transgender participation in swimming.

Here are some of the key points of the FINA decision:
  • Transgender athletes who have experienced any part of male puberty will not be eligible to compete in women's swimming events.
  • Transgender athletes will be eligible to compete in a new "open competition" category.
  • The decision is likely to be challenged in court.
  • The decision is likely to have a significant impact on the future of transgender participation in swimming.
