UPSC-CMS 2021 - Obstetrics and Gynecology Practice Questions

Q: Which of the following are absolute contraindications of Combined Oral Contraceptive (COCs)? 1. Arterial or venous thrombosis history 2. Severe hypertension 3. Gestational trophoblastic neoplasia 4. Diabetes with vascular complications

1, 2 and 4. ***1, 2 and 4*** - A history of **arterial or venous thrombosis** (e.g., deep vein thrombosis, pulmonary embolism, stroke, myocardial infarction) is an absolute contraindication due to the increased risk of clotting associated with estrogen in COCs. - **Severe hypertension** (systolic ≥160 mmHg or diastolic ≥100 mmHg) is a contraindication because COCs can exacerbate blood pressure control and increase the risk of cardiovascular events. - **Diabetes with vascular complications** (e.g., nephropathy, retinopathy, neuropathy, macrovascular disease) indicates advanced microvascular or macrovascular disease, making COCs unsafe due to increased cardiovascular risk. *1, 3 and 4* - While a history of **arterial or venous thrombosis** and **diabetes with vascular complications** are absolute contraindications, **gestational trophoblastic neoplasia** itself is generally not an absolute contraindication to COCs once the disease is in remission or resolved. - The primary concern with gestational trophoblastic neoplasia is avoiding pregnancy during the monitoring period, for which COCs can be used, although other methods may be preferred. *2, 3 and 4* - **Severe hypertension** and **diabetes with vascular complications** are absolute contraindications, but **gestational trophoblastic neoplasia** is not. - The use of COCs in gestational trophoblastic neoplasia is generally considered acceptable after successful treatment and during the follow-up period to prevent pregnancy. *1, 2 and 3* - **Arterial or venous thrombosis history** and **severe hypertension** are absolute contraindications. - However, **gestational trophoblastic neoplasia** is not an absolute contraindication for COCs once the patient has been successfully treated and is being monitored.

Q: After male sterilization, additional contraceptive protection is

needed for 2 to 3 months. ***needed for 2 to 3 months*** - After **vasectomy**, residual **sperm** distal to the ligation site can remain in the ejaculatory ducts and vas deferens. - It takes approximately **20 ejaculations** or **2 to 3 months** for these sperm to be cleared from the reproductive tract, requiring additional contraception until **azoospermia** is confirmed. *not needed* - This option is incorrect because the male reproductive tract is not immediately sterile after a vasectomy due to the presence of **pre-existing sperm**. - Without additional contraception, there is a risk of **unintended pregnancy** until sterility is confirmed by follow-up testing. *needed for 1 to 2 months* - While closer, a duration of **1 to 2 months** may not be sufficient for all residual sperm to be cleared from the system. - The standard recommendation often extends to **3 months** or a specific number of ejaculations to ensure complete sterility. *needed for 1 month* - This duration is generally too short to ensure the complete clearance of **viable sperm** from the ejaculatory ducts after a vasectomy. - Relying on this period alone would carry a higher risk of **contraceptive failure**.
