Anal examinations as proof of same-sex conduct

The shape, tone, or condition of the anus and anal sphincter was treated as physical evidence that a person had engaged in receptive anal intercourse.

Current understanding

Current understanding

Anal examinations cannot reliably determine whether someone has previously engaged in consensual receptive anal intercourse. The supposed forensic signs descend from discredited nineteenth-century theories and have no scientifically valid evidentiary value.

Institutional episode

Egypt

2001–presentPolicy basis

Egyptian prosecutors have repeatedly referred men and transgender women accused of “debauchery” to the Justice Ministry’s Forensic Medicine Authority for anal examinations intended to produce evidence of receptive anal sex. The practice is documented from the 2001 Queen Boat prosecutions into the 2020s. A 2024 civil-society submission documented 45 prosecution referrals for forced anal examinations between July 2019 and June 2024, while recent human-rights reporting states that the resulting forensic reports continue to be used against defendants despite the absence of scientific validity.

Institutions

  • Forensic Medicine Authority (مصلحة الطب الشرعي)
  • Egyptian Public Prosecution (النيابة العامة)
  • Ministry of Justice (وزارة العدل)

Documented consequences

  • Forced anal examinations
  • Medical reports used in prosecutions
  • Conviction and imprisonment for consensual same-sex conduct
  • Cruel, degrading and potentially torturous treatment

Institutional machinery

Public prosecutors refer defendants accused of “debauchery” for examination; the Ministry of Justice’s Forensic Medicine Authority performs the examinations and produces reports used as evidence. Police make arrests and escort detainees, but the decisive medico-legal chain is prosecution referral → Forensic Medicine Authority examination → court use of the report. Recent documentation shows that this chain continued well beyond 2017 and remained in operation into the 2020s.

Lebanon

2012–2015Policy basis

In 2012, Lebanese public prosecutors ordered forensic anal examinations of men arrested on suspicion of homosexual conduct, and examination results contributed to criminal charges. The Lebanese Order of Physicians condemned the tests as medically and scientifically useless and a form of torture. The practice did not end immediately: the public prosecutor’s 2012 directive still allowed examinations under purported consent and treated refusal as evidence, and later reporting documented continued use or threats of use through 2015.

Institutions

  • Cassation Public Prosecution
  • Internal Security Forces
  • Lebanese Order of Physicians

Documented consequences

  • Forced anal examinations
  • Medical evidence used in criminal charges
  • Cruel and degrading treatment

Institutional machinery

Internal Security Forces arrests fed suspects into a medico-legal process in which public prosecutors could order forensic anal examinations. The Cassation Public Prosecution sat at the top of the national prosecutorial hierarchy; its 2012 directive did not impose a categorical ban, but permitted examinations with purported consent and treated refusal as incriminating. The Lebanese Order of Physicians separately instructed doctors not to perform the tests. Human Rights Watch documented continued examinations or threats of examination in 2014 and 2015.

Kenya

2015–2018Officially endorsed

After two men were arrested in Kwale in 2015, state investigators obtained a magistrate’s order and took them to Makadara General Hospital for forced examinations intended to provide evidence of same-sex conduct. In 2018 the Court of Appeal held that the examinations violated their rights. The judgment recorded the medical objection that anal examination cannot establish whether a person had engaged in the alleged conduct, matching international medical consensus that such tests are scientifically invalid.

Institutions

  • Chief Magistrate Ukunda Law Courts
  • DCIO, Msambweni Police Station
  • Makadara General Hospital, Kwale

Documented consequences

  • Court-authorized forced anal examinations
  • Police transport and coercive medical examination of accused men
  • Use of supposed anatomical evidence in a criminal prosecution
  • Violation of privacy, dignity and protection from degrading treatment

Institutional machinery

In a 2015 criminal investigation, the prosecution sought medical examinations intended to establish same-sex conduct, a magistrate authorized the process, and a public hospital examined the two men. The Kenyan Court of Appeal later reconstructed that institutional chain and held in 2018 that the forced anal examinations violated constitutional rights and could not scientifically establish the alleged conduct.

Kazakhstan

2016–presentPolicy basis

Kazakhstan’s Ministry of Justice forensic system maintains a methodology for examining men in sexual-crime investigations that treats several chronic anorectal features as characteristic of systematic receptive male-male intercourse. It instructs examiners to assess sphincter tone by digital examination and lists funnel-shaped or gaping appearance, smoothed folds, sphincter relaxation and mucosal coloration as characteristic changes in “systematic” passive partners. Modern forensic consensus rejects those features as reliable evidence that a person has previously engaged in consensual receptive anal intercourse.

Institutions

  • Center for Forensic Examinations, Ministry of Justice of the Republic of Kazakhstan

Documented consequences

  • Invasive forensic examination of the anus and rectum
  • Anatomically unsupported inference about repeated receptive anal intercourse
  • Potentially misleading expert evidence in criminal investigations

Institutional machinery

Kazakhstan does not criminalize consensual same-sex relations; this methodology is framed for investigations of sexual crimes. Even so, the Ministry of Justice forensic methodology directs experts to examine the anus and rectum for supposed signs characteristic of a “passive partner,” including sphincter tone, funnel-shaped or gaping appearance and smoothed radial folds. The methodology was approved by the state forensic centre’s Scientific Council in December 2016 and remains published by the Ministry of Justice forensic system.

Uzbekistan

2017–presentPolicy basis

Uzbek law-enforcement authorities have ordered forced anal examinations to obtain supposed evidence for prosecutions under Article 120 of the Criminal Code. A documented 2021 case shows a Tashkent court relying in part on a forensic report that treated superficial tears, smoothed radial folds and weakened sphincter tone as evidence of anal sex. The practice remained current in 2025, when two men in Tashkent were reportedly subjected to non-consensual forensic anal examinations, and a June 2026 multi-organization statement describes involuntary invasive examinations as an ongoing enforcement practice associated with Article 120.

Institutions

  • Ministry of Internal Affairs of the Republic of Uzbekistan
  • State forensic medical examiners
  • Criminal courts applying Article 120 of the Criminal Code

Documented consequences

  • Forced anal examinations in detention
  • Medical reports used as evidence of consensual same-sex conduct
  • Criminal convictions, house arrest and imprisonment
  • Cruel, degrading and potentially torturous treatment

Institutional machinery

Law-enforcement officials order forensic anal examinations of men detained under Article 120, which criminalizes consensual same-sex relations between men. Medical reports have been introduced as evidence in prosecutions, and courts have relied on supposed anatomical signs such as smoothed radial folds and weakened sphincter tone. Reporting in 2025 and a June 2026 joint statement document the practice as continuing alongside intensified Article 120 enforcement.
