NEET-PG 2014 - Obstetrics and Gynecology PYQs Practice Questions

Q: Twin pregnancy, but due to two different men is called:

Superfecundation. ***Superfecundation*** - This phenomenon occurs when **two separate ova** are fertilized by **sperm from two different males** during the same menstrual cycle. - This results in fraternal (dizygotic) twins with different biological fathers, which is genetically rare but biologically possible. *Superfetation* - This occurs when a **second, new pregnancy** is established in an already pregnant individual, meaning two pregnancies at different stages of development coexist. - This is extremely rare in humans and typically implies fertilization of an ovum released during an ongoing pregnancy. *Both of the options* - These terms describe distinct biological phenomena with different underlying mechanisms. - Superfecundation involves concurrent fertilization by different fathers, while superfetation involves sequential fertilization resulting in pregnancies of different gestational ages. *None of the options* - Superfecundation accurately describes the scenario of twins conceived by two different fathers. - Therefore, there is a correct option among the choices provided.

Q: Which condition is most commonly associated with female sexual dysfunction characterized by painful intercourse?

Vaginismus. ***Vaginismus*** - **Vaginismus** is a condition characterized by involuntary spasms of the muscles surrounding the vaginal opening, leading to painful intercourse (**dyspareunia**) or inability to complete penetration. - It's a common cause of female sexual dysfunction where the primary symptom is **pain or difficulty with vaginal penetration**. *Absence of ovary* - The **absence of ovaries** primarily affects hormone production and fertility but does not directly cause involuntary vaginal muscle spasms leading to painful intercourse. - While it can lead to vaginal atrophy due to lack of estrogen, which might cause painful intercourse, it's not the most direct or common cause of the specific dysfunction described. *Gonadal dysgenesis* - **Gonadal dysgenesis** refers to abnormal development of the gonads, often leading to hormonal imbalances and infertility. - This condition is not typically associated with muscle spasms causing painful intercourse; its main manifestations are related to sexual development and endocrine function. *Intersex condition* - An **intersex condition** involves atypical development of internal and external sexual anatomy. - While intersex conditions can lead to a variety of sexual health issues, they do not inherently or most commonly present with the involuntary vaginal muscular spasms characteristic of vaginismus.
