What should be ordered next after STI testing in the male infertility workup?

In the context of a male infertility workup, after conducting STI testing, the next logical step is to perform a sperm analysis. This is critical because sperm analysis provides essential information about the quality and quantity of sperm, which are key factors in male fertility. The parameters assessed during a sperm analysis include semen volume, sperm concentration, motility (movement), and morphology (shape).

Identifying any abnormalities in these parameters can guide further investigations and management options. For instance, if the sperm analysis indicates low sperm count or motility, this may prompt further evaluation of hormonal levels or potential underlying conditions affecting fertility. Establishing the status of sperm health is fundamental in any infertility assessment, making it a priority after ruling out infectious causes through STI testing.

Other tests, such as hormonal panels, genetic testing, or testicular ultrasounds, may follow based on the findings of the sperm analysis or might be indicated in specific scenarios. However, the sperm analysis serves as the immediate next step in determining the male partner's reproductive potential.
