Is fadogia agrestis good for men to boost testosterone?

Fadogia agrestis may raise testosterone in some men by increasing luteinizing hormone (LH), but the evidence is limited and its long-term safety is uncertain. 1

• Mechanism: It may increase LH release and sensitivity to LH at its receptors; LH then stimulates the testes’ Leydig cells to produce testosterone. 2
• Safety concern: Testicular-cell toxicity has been reported in animal studies, especially at high doses. The human safety evidence is not strong enough to establish that long-term use is safe. 3
• Cycling and monitoring: One clinician discussed cycling it three weeks on, one week off, and recommended bloodwork rather than using it without monitoring. 4

So it may help, but the potential benefit should be weighed against uncertain safety and monitored with a physician and blood tests. 4
