సున్తీ లేదా సున్నతి (Male circumcision) పురుషాంగానికున్న పూర్వచర్మాన్ని తొలగించడం. The word "circumcision" comes from Latin circum (meaning "around") and cædere (meaning "to cut"). Early depictions of circumcision are found in cave paintings and Ancient Egyptian tombs, though some pictures are open to interpretation. Religious male circumcision is considered a commandment from God in Judaism. In Islam, though not discussed in the Qur'an, male circumcision is widely practised and most often considered to be a sunnah. It is also customary in some Christian churches in Africa, including some Oriental Orthodox Churches.
ప్రపంచ ఆరోగ్య సంస్థ (WHO), అంచనాల ప్రకారం ప్రపంచంలో సుమారు 30% మంది పురుషులు సున్తీ చేసుకొంటూ ఉంటే, అందులో సుమారు 68% మంది ముస్లింలు. ఈ అంచనాలు ఆయా దేశాల మతం మీద ఆధారపడుతుంది. మతపరమైన సున్తీ యౌవనం ప్రారంభంలో చేస్తారు; కానీ కొన్ని దేశాలలో పుట్టిన వెంటనే జరపడం ఆచారంగా
