In addition to testosterone, what other test might be conducted for infertility issues?

Prolactin is a hormone that plays a significant role in reproductive health, particularly in the regulation of the menstrual cycle and the production of breast milk. When evaluating infertility issues in both men and women, measuring prolactin levels is important because elevated levels can interfere with the normal function of the reproductive system. In women, high prolactin can lead to irregular menstrual cycles, which may complicate conception, while in men, it can be associated with lowered testosterone levels and decreased libido. Therefore, testing for prolactin alongside testosterone offers critical information in the assessment of infertility.

The other options, such as ALB (albumin), AST (aspartate aminotransferase), and B12 (vitamin B12), are not typically relevant in the context of infertility testing. Albumin is primarily a protein made by the liver and is often measured to assess liver function or nutritional status. AST is an enzyme found in the liver and other tissues; it is mainly used to diagnose liver disease or muscle damage. Vitamin B12 is important for nerve function and the production of DNA and red blood cells but is not directly tied to infertility assessments. Thus, while they are important tests in their respective contexts, they do not provide the necessary insights related
