Contraception and Family Planning Practice Questions

Q: Spermicidal jelly acts through what mechanism?

Lysis of sperm cell membrane. ***Lysis of sperm cell membrane*** - Spermicidal jelly typically contains a chemical agent, most commonly **nonoxynol-9**, which acts as a **surfactant**. - This surfactant mechanism disrupts the **lipid bilayer of the sperm cell membrane**, leading to its rupture and cell death. *Acrosomal enzyme activity* - Spermicides do not primarily work by affecting **acrosomal enzymes**, which are crucial for fertilization by breaking down the egg's outer layers. - While sperm death would prevent acrosomal reaction, it's not the direct mechanism of action of spermicides. *Alteration of cervical mucus* - While some contraceptive methods, such as **progestin-only pills**, alter cervical mucus to impede sperm passage, this is not the primary mechanism of action for **spermicidal jelly**. - Spermicides aim to directly kill sperm rather than solely hindering their movement through the cervix. *Inhibition of glucose uptake by sperm* - Spermicides do not primarily function by inhibiting the **metabolic processes** of sperm, such as glucose uptake. - Their main action is a direct cytotoxic effect on the **sperm cell structure**.

Q: What is the hormonal contraceptive of choice in a lactating woman?

Progestin-only pill. ***Progestin-only pill*** - The **progestin-only pill** is generally considered the hormonal contraceptive of choice for lactating women because it does not negatively impact **milk supply** or the **growth of the infant**. - Progestin-only methods have minimal to no effect on the **quality or quantity of breast milk**. *Combined oral contraceptive* - **Combined oral contraceptives (COCs)** contain both estrogen and progestin, and the **estrogen component** can **reduce milk supply**. - Due to the potential for impacting lactation, COCs are generally **not recommended** for use in the early postpartum period while a woman is breastfeeding exclusively. *Centchroman (non-hormonal option)* - **Centchroman** is a non-hormonal contraceptive that functions as a **selective estrogen receptor modulator (SERM)**. While it is an oral contraceptive, it is not a hormonal choice in the same category as progestin-only or combined pills and is less commonly used as a first-line option specifically for lactating women over progestin-only methods. - While it may not affect lactation, it is **not the 'hormonal contraceptive of choice'** among the given options, and its efficacy and availability may vary. *Multiphasic oral contraceptive* - **Multiphasic oral contraceptives** are a type of combined oral contraceptive, meaning they contain both **estrogen and progestin**, with varying doses throughout the cycle. - Similar to other combined hormonal contraceptives, the **estrogen content** can **suppress milk production**, making it an unsuitable choice for lactating women.

Q: Which of the following is not typically used as an emergency contraceptive?

Estrogen. ***Estrogen*** - High-dose estrogen alone is **not typically used for emergency contraception** due to a high incidence of adverse effects (severe nausea and vomiting) and significantly lower effectiveness compared to progestin-only or selective progesterone receptor modulator methods. - The **Yuzpe method** (an older emergency contraceptive regimen) used **combined** oral contraceptives containing both estrogen and progestin, but estrogen alone has no role in modern emergency contraception. *Combined oral pills* - Certain combined oral contraceptive pills (containing both estrogen and progestin) can be used as **emergency contraception in specific dosages**, known as the **Yuzpe method**. - This method involves taking two doses of combined pills within 72 hours of unprotected intercourse, but it has largely been superseded by more effective and better-tolerated options. *Ulipristal acetate* - **Ulipristal acetate is a selective progesterone receptor modulator (SPRM)** that is highly effective as an emergency contraceptive. - It can be taken up to **120 hours (5 days)** after unprotected intercourse and is **more effective than levonorgestrel**, especially between 72-120 hours. - It works primarily by **delaying or inhibiting ovulation**. *Levonorgestrel* - **Levonorgestrel is the most widely used progestin-only emergency contraceptive pill**, typically taken as a single 1.5 mg dose or two 0.75 mg doses. - It is most effective when taken within **72 hours** of unprotected intercourse. - It primarily works by **delaying or inhibiting ovulation** and preventing fertilization.

Q: Which of the following tubal sterilization procedures is considered the least effective?

Hysteroscopic occlusion. ***Hysteroscopic occlusion*** - This method, using devices like the **Essure system** (discontinued in 2018), historically had higher reported failure rates and has been associated with more complications compared to surgical ligation methods. - Its effectiveness relies on adequate fibrosis around the device to block the fallopian tubes, which can take several months, and requires a **confirmation hysterosalpingogram (HSG)**. - Failure rates reported at **0.9-1.6%**, making it the least effective among standard tubal sterilization methods. *Laparoscopic Yoon's ring method* - Involves applying a **silastic band (Falope Ring or Yoon's Ring)** to a loop of the fallopian tube, causing necrosis and effective occlusion. - It is a highly effective method with a low failure rate of approximately **0.5%** when performed correctly. *Pomeroy's method* - Involves ligating and excising a section of the fallopian tube, widely recognized as one of the **most effective** and commonly performed tubal ligation techniques. - Its high success rate (failure rate **0.4%**) is due to the complete transection of the tube, creating a physical barrier to sperm and egg meeting. *Vaginal fimbriectomy* - This procedure involves the removal of the **fimbrial portion of the fallopian tube** via a vaginal approach, making it an effective sterilization method. - While effective, it is less commonly performed than laparoscopic methods and offers similar efficacy to other surgical ligation techniques.

Q: In the context of tubal ligation, what is the failure rate of Pomeroy's technique?

0.5-1%. ***0.5-1%*** - Pomeroy's technique generally has a reported **failure rate** in the range of **0.5% to 1% per 100 women-years**. - This rate indicates that despite being a highly effective method of sterilization, a small percentage of women may still experience **pregnancy** after the procedure. *0.1-0.5%* - This range is typically considered too low for the **failure rate** of Pomeroy's technique, which is known to have a slightly higher but still very effective rate. - While some highly effective contraceptive methods might approach this range, tubal ligation techniques like Pomeroy's have a small, but consistently reported, higher failure rate. *1-2%* - While still low, this range is generally considered to be a slightly **higher than average failure rate** for Pomeroy's technique. - An incidence in this range might suggest a technical issue during the procedure or a less effective method in general. *5-10%* - This range represents a significantly **higher failure rate** than what is typically associated with Pomeroy's technique, which is recognized as a very effective method of permanent sterilization. - A failure rate this high would be comparable to less effective or temporary contraceptive methods, rather than a surgical sterilization procedure.

Q: Antiprogesterone compound RU-486 is effective for inducing abortion if the duration of pregnancy is what?

63 days. ***63 days*** - **Mifepristone (RU-486)**, an antiprogesterone, is most effective for medical abortion when used within 63 days (9 weeks) of gestation. - Its efficacy decreases and the risk of incomplete abortion or complications increases beyond this timeframe, making surgical options more suitable for later pregnancies. *72 days* - While still relatively early in pregnancy, **mifepristone's efficacy** starts to decline after 63 days, and the recommended window for optimal success of a medical abortion is generally within the first 9 weeks. - Beyond 63 days, the need for **surgical intervention** or repeat doses of misoprostol becomes more likely, and the overall success rate for medical abortion is reduced. *88 days* - By 88 days (approximately 12.5 weeks), medical abortion with mifepristone alone becomes significantly less effective and often requires **surgical evacuation**. - The risk of **incomplete abortion**, heavier bleeding, and other complications substantially increases, highlighting the importance of earlier intervention. *120 days* - At 120 days (approximately 17 weeks), medical abortion with mifepristone would be largely ineffective and unsafe as a primary method for pregnancy termination. - Pregnancies at this stage typically require **surgical procedures** like D&E (dilation and evacuation) due to the size of the fetus and placenta.

Q: Absolute contraindication of IUCD is:

Pelvic tuberculosis. ***Pelvic tuberculosis*** - **Pelvic tuberculosis** is an **absolute contraindication** for intrauterine contraceptive device (IUCD) insertion due to the increased risk of dissemination of the infection and worsening of the disease. - Inserting an IUCD in a patient with active pelvic tuberculosis can lead to severe complications, including **pelvic inflammatory disease (PID)**, abscess formation, and systemic infection. *Endometriosis* - **Endometriosis** is generally not an absolute contraindication for IUCD use, especially for **levonorgestrel-releasing IUCDs**, which are often used to manage symptoms like dysmenorrhea and heavy menstrual bleeding in these patients. - The hormonal effects of some IUCDs can actually be beneficial in reducing the growth of endometrial implants. *Iron deficiency anaemia* - **Iron deficiency anemia** is not an absolute contraindication for IUCDs, particularly the **levonorgestrel-releasing IUCDs**, which reduce menstrual blood loss and can improve iron status. - For copper IUCDs, which can increase menstrual bleeding, a patient with iron deficiency anemia might experience worsening symptoms, but this is a **relative contraindication** that can be managed, not an absolute one. *Dysmenorrhea* - While **dysmenorrhea** can be a concern with some IUCDs, especially copper IUCDs which can sometimes worsen pain, it is not an absolute contraindication. - **Levonorgestrel-releasing IUCDs** are often prescribed to manage and even alleviate dysmenorrhea due to their progesterone-like effects on the endometrium.

Q: Which contraceptive method is considered most effective for couples seeking reliable birth control?

Intrauterine contraceptive device (IUCD). ***Intrauterine contraceptive device (IUCD)*** - **IUCDs** (both hormonal and copper) are considered among the most effective reversible contraceptive methods, with typical use failure rates less than 1%. - Their long-acting nature means no daily effort is required, making them highly reliable for couples seeking **consistent birth control**. *Barrier methods (e.g., condoms)* - While effective when used consistently and correctly, **barrier methods** have a higher typical-use failure rate (around 13-18%) compared to IUCDs due to user error or inconsistent use. - They also provide protection against **STIs**, but are less effective for pregnancy prevention in real-world scenarios. *Combined oral contraceptives (OCPs)* - **OCPs** are highly effective when taken perfectly, but their typical-use failure rate is around 7%, primarily due to missed pills. - They require daily adherence and can have side effects that might impact compliance, making them less reliable than IUCDs for some users. *Progestin-only pill* - The **progestin-only pill** (mini-pill) is effective but requires strict adherence to a daily schedule, ideally at the same time each day, making it very sensitive to missed doses. - Its typical-use failure rate is similar to or slightly higher than combined OCPs due to this strict dosing requirement, making it generally less reliable than IUCDs.

Q: Which of the following reduces the risk of pelvic inflammatory disease (PID)?

Oral contraceptive pills (OCPs). ***Oral contraceptive pills (OCPs)*** - OCPs **thicken cervical mucus**, which creates a barrier that can prevent the ascent of bacteria from the vagina into the upper reproductive tract. - This cervical mucus barrier reduces the risk of cervical infection spreading to the uterus and fallopian tubes, thereby **lowering the incidence of PID**. *Copper T IUCD* - The Copper T IUCD is associated with a **slightly increased risk of PID** in the first few weeks after insertion, especially in women with pre-existing sexually transmitted infections (STIs). - It does not offer protection against ascending infections and can potentially facilitate their spread if the cervical barrier is compromised. *TODAY vaginal sponge* - The TODAY vaginal sponge contains **spermicide and acts as a barrier contraceptive**, but it does not protect against STIs, which are the primary cause of PID. - Some studies suggest that spermicides can **irritate vaginal mucosa**, potentially increasing susceptibility to certain infections. *Spermicidal agents* - Spermicidal agents primarily work by **immobilizing and killing sperm** to prevent pregnancy. - They **do not protect against STIs** and, in some cases, frequent use can cause vaginal and cervical irritation, potentially making the user more vulnerable to infections that can lead to PID.

Q: What is the most common site of ligation by laparoscopic ring in female sterilization?

Isthmus. ***Isthmus*** - The **isthmic portion** of the fallopian tube is the most common and preferred site for laparoscopic ring application (e.g., Falope ring or Yoon ring) in female sterilization. - This segment is chosen because it is relatively **straight**, has a **narrow lumen**, and possesses a **thick muscular wall**, making it ideal for occlusion and effective contraception. *Fimbrial* - The **fimbrial end** is the most distal part of the fallopian tube, characterized by finger-like projections that capture the ovum. - Ligation at this site is less common due to its **delicate structure** and proximity to the ovary, increasing the risk of **ovarian damage** or incomplete occlusion. *Cornual* - The **cornual portion** is the segment of the fallopian tube that passes through the muscular wall of the uterus. - This site is generally avoided for ring application due to the **risk of uterine perforation** and increased **bleeding** from the uterine arteries within the myometrium. *Ampullary* - The **ampullary portion** is the widest and longest part of the fallopian tube, where fertilization typically occurs. - Its **dilated lumen** and **tortuous nature** make it less suitable for secure and effective ring placement, as the ring may not fully occlude the tube.
