Contraception by Dr wajiha sajid
This document summarizes various contraceptive methods including barrier methods like condoms and diaphragms, hormonal methods like oral contraceptive pills and injectables, intrauterine devices, and permanent sterilization methods. It describes how each method works to prevent pregnancy and lists the advantages and disadvantages of each. Reversible long-acting methods like IUDs and implants are highly effective but have potential side effects while barrier methods are less effective but have fewer health risks. Permanent sterilization via tubal ligation or vasectomy is intended to be very effective but cannot be reversed.

- 37. Sterilization Sterilization :femalebilateral tubal ligation and male vasectomy are permenant method of contraception and highly effective. • They are generally chosen by relatively older couple who are sure that they completed their family. Also individual who carry a genetic disorder may choose to be sterlized. Sterilization methods include: 1- Vasectomy in males. 2- Tubal Ligation in females .
- 38. Bilateral Tubal Ligation This involve mechanically blockage of both fallopian tube to prevent the sperm reaching and fertilizing the oocyte sterilization performed by laparoscopically(under GA) or through a suprapubic “mini-laparotomy” During caesarean section Failure rate: 0.5%
- 39.
- 40. Tubal Ligation Advantages: • intendedto be permanent • highly effective • safe • quick recovery • lack of significant long- term side effects • cost effective Disadvantage: possibility of patient regret • difficult to reverse • future pregnancy could require assisted reproductive technology (such as Invitro Fertilization) • more expensive than vasectomy
- 41. Vasectomy • Vasectomy involvedivision of the vas deferens on each side to prevent the release of sperm during ejaculation. • Easier than tubal ligation. • Usually done under local • anesthesia. • Failure rate: 0.1%.
- 42. Vasectomy • Advantages: • permanent,effective,safe,quick recovery • lack of significant long-term side effects • cost effective; less expensive than tubal ligation Disadvantages: • reversal is difficult, often unsuccessful • not effective until all sperm cleared from the reproductive tract (may take up to 12 w) • no protection from STD
- 43. Cont. Complication of vasectomy: •Immediately bleeding, wound infection • At the cut of vas deferns small lump will apear as a result of a local inflammation response this is called sperm granuloma it needs surgical excision. • some men develop anti-sperm antibody following vasectomy
