(b) Coitus interrupts (Withdrawal)

Hormonal
Hormonal birth control refers to birth control methods that contain synthetic forms of hormones.
- Two types of oral contraceptives available: Combined oral contraceptive (COC)- contains both oestrogen and progestin and Progestin-only Contraceptive (POC).
- The woman takes a pill every day at about the same time for 21 days, then stops for 7 days to get her period.

- Users have to remember to take the pills every day, or it will be not effective in preventing pregnancies.
- Hormonal progestin intramuscular injection given every 3 months during the first five days of a woman’s period.
- The hormones thicken the mucous at the uterine opening so that sperm won’t pass through.
- It also thins out the lining of the uterus to prevent pregnancy.
- Progestin containing implant to be inserted under the skin by a medical professional over inner side of forearm.
- The implant releases small amounts of hormone over next 3-5 years to prevent ovulation, thicken the mucous and thin out uterus lining.
- A patch which contains hormones will be adhered on the upper arm once a week for three weeks.
- No patch will be used on the 4th week to trigger menstruation.
- It is easy to use and non-invasive.
Emergency Contraception
Reasons for choosing EC, a contraceptive method to prevent pregnancy after a non-protected intercourse:

(b) Intrauterine Contraception Device
- A copper intrauterine device can be inserted within 5 days of unprotected intercourse and removed at the next menstrual period to prevent implantation.
- It benefits by preventing the rate of unplanned pregnancies and abortions.
Permanent contraception
- Vasectomy is a permanent surgical procedure to close or block the vas deferens (the tube which carries the sperm).
- Another form of contraception is needed until a semen analysis shows no sperm.
(b) Tubal-ligation for female:
- Female sterilization by tubal ligation is a permanent surgical procedure where the fallopian tube (which carries egg from the ovary) will get disconnected.
- Through a laparoscope, doctor will make small incision over the abdomen to either clip, burn or remove the fallopian tube.
- Abdominally, during caesarean section, doctor can assess the fallopian tube to clip or remove them.

A patient’s choice of contraceptive method involves factors such as efficacy, safety, benefits, cost and personal consideration.
