Top studies from 5+ peer-reviewed papers
Ogunro OB et al. • Reproductive sciences (Thousand Oaks, Calif.) (2023)
“The Author(s), under exclusive licence to Society for Reproductive Investigation.”
Key Findings:
- Contrastingly, AEFAS like sildenafil citrate increased (p < 0.05) the penile and testicular NO, cGMP, catalase, SOD, T-SH, GSH and GST and reduced AChE, PDE5, arginase, ACE, TBARS and H2O2 to levels that compared favourably (p > 0.05) with those of sham control.
- The study concluded that AEFAS restored the NO/cGMP pathway and ED-associated key enzymes in the penile and testicular tissues of male rats via antioxidant means.
- The study recommended the use of aqueous extract of Fadogia agrestis stem in managing ED after clinical trials.© 2022.

- The original animal study showed increased serum testosterone but also testicular toxicity at higher doses
- Concerns about heavy metal contamination and lack of standardization in commercial products
