**Core Concept**
Cervical infertility refers to a condition where the cervix prevents sperm from reaching the uterus, thereby hindering fertilization. This can be due to various factors, including cervical stenosis, cervical mucus abnormalities, or cervical scarring. Understanding the pathophysiology of cervical infertility is crucial for selecting the appropriate treatment.

**Why the Correct Answer is Right**
Treatment options for cervical infertility aim to bypass or correct the cervical obstruction. **Intrauterine insemination (IUI)** involves directly depositing sperm into the uterus, bypassing the cervix. **In Vitro Fertilization (IVF)** is another treatment option where oocytes are fertilized outside the body, and the resulting embryo is transferred to the uterus. **Hysteroscopic metroplasty** is a surgical procedure that involves correcting uterine anomalies that may be contributing to cervical infertility.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is not provided, but it could potentially be a correct treatment for cervical infertility.
**Option B:** This option is not provided, but it could potentially be a correct treatment for cervical infertility.
**Option C:** This option is not provided, but it could potentially be a correct treatment for cervical infertility.

**Clinical Pearl / High-Yield Fact**
In cases of cervical infertility, it's essential to rule out other underlying causes such as endometriosis, tubal damage, or ovulatory disorders. A thorough evaluation of the couple's infertility workup, including semen analysis, ovulation induction, and imaging studies, is necessary before selecting a treatment plan.

**Correct Answer: D.**
