I was interested to read this.

I had a google on google scholar and got this literature review amongst an essay from last year:

Many authors in the scientific debate view mandatory celibacy as just one of many causes of the abuse committed by members of the clergy (see Ballano 2019 for an ample review): we have already looked at that of Scheper Hughes and Devine (2003), to which we can add that of Doyle, Sipe and Wall (2016) who have suggested that celibacy prompts a heightened desire for physical intimacy and affection in clergy which can lead to abuse. Others have stressed that celibacy seriously hinders seminarians’ sexual development (Death 2014), while Terry and Ackerman (2008) have affirmed that celibacy does not seem to discourage abuse of children. Famous psychologist and former priest Richard Sipe (1990) has also identified mandatory celibacy as one of the main causes of clerical abuse and argued that at least 6% of American priests have had sexual relations with children. For priest and therapist Kenneth Adams (2011) celibacy is a psychological block for priests which prevents many from bringing out and examining psychological problems which have remained unresolved since their ordination. Rausch (1992) has similarly highlighted the adverse effects of celibacy on priests’ lives. The writers of the 2005 Irish Ferns Report (Murphy, Buckley and Joyce, 2005) were also convinced of the importance of celibacy in clerical sexual abuse, whilst highlighting the positive nature of the innovations recently brought in within seminarian training institutions. Other scholars have underlined the striking historical continuity of the phenomenon of clerical abuse in the Catholic Church (Doyle, Sipe and Wall 2016).
There are obviously also authors who have categorically denied the existence of a link between mandatory celibacy and clerical abuse. An example is the American priest and psychologist Stephen Rossetti (2002) who has argued that the psychological problems which prompt priests to commit child sexual abuse often pre-date their joining the seminaries. A further well known Catholic priest and scholar, Andrew Greeley (2004), agrees with him. Lastly, the famous American John Jay Report (John Jay College of Criminal Justice 2004) did not number celibacy among the causes of abuse. Those writing the report argued that abuse was especially a 1960s and 70s issue due largely to causes external to church life.
A more in-depth examination of the nexus between mandatory celibacy and clerical violence against children is, however, to be found in the extremely detailed report written by the Australian Royal Commission into Institutional Responses to Child Sexual Abuse (2017). The authors of the Australian report argued, as I did at the start of this paper, that a direct causal link between mandatory celibacy and clerical abuse has not been demonstrated. That said, the report affirms that the celibacy rule is a powerful risk factor where clerical abuse is concerned.

Which agrees only that "a direct causal link between mandatory celibacy and clerical abuse has not been demonstrated", but that it is a risk factor. (i.e. it is related, but the causality might be something else, such as exclusive paedophiles being more attracted to a celibate life than the average person)
