Oh... you walked right into that one.

Sport and Transgender People: A Systematic Review of the Literature Relating to Sport Participation and Competitive Sport Policies

Slight problem is that all but one of the 'studies' it looks at are questionnaires that don't measure strength at all. They just ask opinions of the transgender athletes, who are hardly impartial.

The majority of the studies were qualitative in nature, all of which employed interviews. The remaining two research articles included an experimental study [23] and a cross-sectional survey [30].

The only non questionnaire/interview study that actually measured strength differences showed that transwomen were still significantly stronger after a year on HRT, and also significantly stronger than transmen who'd been on testosterone for a year.

Transsexuals and competitive sports

In both M-F and F-M, height was a strong predictor of muscle mass. Androgen deprivation of M-F decreased muscle mass, increasing the overlap with untreated F-M, but mean muscle mass remained significantly higher in M-F than in F-M. Androgen administration to F-M increased muscle mass without inducing an advantage over nontreated M-F. The conclusion is that androgen deprivation in M-F increases the overlap in muscle mass with women but does not reverse it, statistically.

Not the first time I've seen it that 'meta study'. It's not even attempting to pass as science.
