根據香港法律，在懷孕24週前都可以合法地選擇由註冊醫生終止懷孕服務，即以人工方式構成流產，又稱為「人工流產」。不過，懷孕的週數越大，風險相對也越高。一般而言，醫生會先為病人用超聲波做檢查，排除宮外孕。因此， 雖然週數越小風險越低，但都建議最少在5 — 6週後才做決定是否進行人工流產。
在見婦產科醫生的過程中，醫生會向病人解釋終止懷孕的方法及風險。而私家婦產科醫生常用的方法分為兩種：
Medical termination of pregnancy
- 在醫院服用藥物，藥物刺激子宮收縮及排出胚胎組織（6 週或以上）
- Might have risk that the products of conception might not be fully expelled, therefore follow up is required and further operation (Suction evacuation or uterine curettage) might be needed
- No anesthesia is required
- Might experience heavy bleeding, abdominal cramp or side effects of drugs include fever, shivering, nausea, diarrhea and allergy
手術流產（吸宮或刮宮）
- The whole procedure will be carried out in hospital. Patient has to stay in hospital for 1 day
- Undergoes under general or monitored anesthesia
- Suction catheter will be inserted through cervix to empty the uterus by vacuum suction
- Experience shorter duration of bleeding and less pain
- Carries surgical risks
無論哪種終止懷孕的方法都涉及風險，手術後亦有機會出現流血、子宮感染及組織殘留等。建議人工流產手術後一星期亦應該由婦產科醫生覆診檢查。此外，香港部份私家醫院都有宗教背景，因此並非所有醫院都提供終止懷孕服務，詳情請以WhatsApp聯絡卓越醫務中心查詢。
