NMN Shielded Rat Testes From Chemotherapy Damage
Graded Preliminary — a controlled experiment in 32 rats over 28 days; it measured only tissue and cell markers, not fertility, and no humans were studied.
Animal study. Findings may not carry over to people, which is why the grade is capped at Preliminary.

In rats given the cancer drug doxorubicin, testicular tissue stayed in clearly better shape with NMN than without it.
Losing fertility is one of the most serious side effects of chemotherapy for men. Doxorubicin, a widely used cancer drug, is known to harm the testes. In rats, that harm was clearly milder when the animals also received NMN, a compound studied for its possible support of the cell's power plants, the mitochondria.
Researchers split 32 male rats at random into four groups: no treatment, NMN only, doxorubicin only, or both. NMN was injected into the belly cavity over 28 days. Doxorubicin was given six times over twelve days. On the cancer drug alone, the sperm-producing tubes shrank and the tissue looked worse under the microscope. Harmful oxygen compounds rose, the mitochondria lost electrical charge, and a signal of cell death went up. With NMN, all of these changes were weaker.
The study only measured tissue and cell markers. It did not test whether the rats stayed fertile or kept normal hormone levels, which the authors say still needs to be shown. Whether NMN helps men going through chemotherapy was not studied.
