The patient in OPD7398 had which condition?

Sperm production versus a blockage is the key idea here. Azoospermia can come from two main problems: the testicles aren’t making sperm (nonobstructive) or there’s a blockage preventing sperm from getting into the ejaculate (obstructive). In this case, the clues point to impaired sperm production rather than a blockage. Nonobstructive azoospermia means the testes aren’t producing enough sperm, which is why there’s no sperm in the semen despite the absence of a physical obstruction. This typically shows up with signs of testicular issues or testicular failure (for example, higher FSH due to lack of negative feedback), and biopsy would often reveal impaired spermatogenesis or very few/absent sperm cells. The other possibilities don’t fit as well. Obstructive azoospermia would involve normal sperm production with a blockage somewhere in the ducts, so you’d expect signs pointing to an intact production process. Oligospermia means very low but not zero sperm, which isn’t the same as azoospermia. Erectile dysfunction is about the ability to achieve an erection and doesn’t explain the absence of sperm in the ejaculate. So the best match is nonobstructive azoospermia because the scenario aligns with a production problem rather than a ductal obstruction.
