Sexual Offences and Medical Examination
On this page
Direct answer
Sexual offences in law turn on two words — penetration and consent: even the slightest penile penetration of the vagina amounts to rape, consent must be free and voluntary from a person above the age of consent, and the survivor's past sexual conduct is irrelevant to the charge. The doctor's role is not to pronounce rape but to examine respectfully, collect forensic evidence within the useful window (ideally within 72–96 hours), treat injuries and prevent pregnancy and infection. A normal genital examination never excludes rape, and virginity opinions plus the two-finger test are prohibited by the Supreme Court and by current health ministry guidelines.
What you must remember
- Rape in law requires only penetration, not emission or completion; the age of consent is eighteen, and below it consent is legally impossible.
- The survivor's sexual history and character are not relevant; the examination must be conducted, or supervised, by a female registered medical practitioner when the survivor is a woman.
- Consent for the examination is taken from the survivor herself; she may decline any part, treatment never waits for police formalities, the two-finger test is banned, and the vaginal introitus opines nothing about consent or virginity.
- Semen detection: acid phosphatase is a cheap presumptive test; the Florence test yields needle-shaped crystals of choline periodide, the Barberio test needle sheaves of spermine picrate; p30 (prostate-specific antigen) and microscopy for spermatozoa confirm, and about 80 per cent of people secrete ABO antigens in body fluids, enabling grouping.
- Evidence collection within about 72–96 hours: swabs from sites of contact, pubic hair combings, clothing, blood and urine — sealed, labelled, chain of custody.
- General body injuries — grip bruises on wrists, thighs, forearms, bite marks and nail abrasions — often carry more probative weight than genital findings.
- Sodomy and bestiality are defined by the act itself irrespective of gender, and for adult participants consent, not the act, is the legal issue; aggravated categories — custodial, gang and child assault — carry heavier minimum punishment.
- The accused must be examined promptly with consent, documenting potency, injuries and samples — a potency certificate is frequently demanded and equally frequently forgotten; emergency care for the survivor covers contraception up to 72 hours (hormonal) or five days (copper device), infection prophylaxis, 28-day HIV post-exposure prophylaxis and psychological first aid.
The first twenty-four hours with a survivor
A nineteen-year-old reports assault six hours ago. First, a private room, a female chaperone, and consent taken in her own words for examination, collection and police intimation — with the caveat that for an adult she chooses whether to report, while a minor triggers mandatory reporting under child protection law. Second, general examination head to toe: photograph and measure every bruise, grip mark and bite impression, because these corroborate force. Third, forensic collection before cleaning: swabs from the vulva, vagina, perianal region and any site of oral contact, plus combings, clothing in paper bags and blood for grouping and toxicology.
Fourth, the anogenital examination documented in neutral descriptive terms — erythema, tears, their site and age — with no opinion on virginity or consent written anywhere. Fifth, treatment: emergency contraception, sexually transmitted infection prophylaxis, HIV risk assessment for post-exposure prophylaxis, and hepatitis and tetanus status. Sixth, the written report, which records findings and states only that they are "consistent or not consistent with the history given" — the court decides rape, not the doctor. The examination of the accused follows the same discipline: potency, build, injuries the survivor described inflicting, and samples of pubic hair, blood and saliva.
Where the marks are lost
Two systematic errors recur. The first is delay: biological evidence degrades with washing and time — a delayed report is still examined, but the yield falls and the report should say so. The second is over-reading the hymen: examiners ask "does an intact hymen exclude rape?" and the only safe answer is no — penetration of the slightest degree suffices, elastic hymens may not tear, and tears, when present, are dated by healing, not by shape; and the "old ruptured hymen" language of older textbooks has no place in a modern certificate. The Florence test is a viva favourite asked in the negative: it detects semen, not spermatozoa, so a vasectomised man gives a positive Florence with negative sperm microscopy.
Frequently asked questions
Does an intact hymen or absence of genital injury exclude rape?
No; the law requires only slight penetration, elastic tissues may not injure, and most examinations of genuine survivors are normal — consent is a legal, not a genital, conclusion.
What does the Florence test detect and what crystals appear?
Semen: potassium tri-iodide gives brown needle-shaped crystals of choline periodide; it is presumptive and positive even in vasectomised men, unlike sperm microscopy.
Who examines a female survivor of sexual assault?
A registered medical practitioner, with the examination of a woman conducted by or in the presence of a female practitioner, after informed consent.
Why is the two-finger test prohibited?
The Supreme Court has held it violates privacy and dignity and opines nothing about consent; health ministry guidelines forbid recording vaginal introitus laxity or any virginity opinion.
