Which of the following tests may a woman undergo at an infertility clinic to identify potential infertility issues?

A woman undergoing evaluation for infertility may indeed receive a variety of tests to identify potential issues affecting her ability to conceive. Among these, an endometrial biopsy is a procedure that can provide insight into the condition of the uterine lining, which plays a crucial role in successful implantation of an embryo. By examining the endometrial tissue, healthcare providers can assess factors such as hormonal activity, the presence of abnormalities, and the overall receptivity of the uterus.

An endometrial biopsy is often performed if there are concerns about conditions such as endometrial hyperplasia or other potential abnormalities that might impede embryo implantation. It can also help determine whether the uterus is prepared adequately for pregnancy based on the cycle phase.

While the other tests listed are relevant to infertility assessments, they serve different purposes: for instance, chorionic villus sampling is typically performed during pregnancy for genetic testing, a hysterosalpingogram is an X-ray procedure to check the patency of the fallopian tubes, and serum FSH analysis evaluates ovarian function rather than directly assessing uterine health. Therefore, the endometrial biopsy stands out as a direct method to assess uterine factors that could contribute to infertility.
