Aim: To assess the effects of essential oïl from guava leaves on some reproductive parameters.

Methods: Thirty-two male guinea pigs (Cavia porcelus) of three months old and weighing between 350 and 400 g were used. These guinea pigs were divided into 4 groups of 8 animals each. Each group was randomly attributed orally for 60 days one of the following guava leaf essential oil doses: 0 (control group), 80, 100 and 120 μl of oil per kg body weight. At the end of treatment, all animals were sacrificed to assess the reproductive parameters.

Results: Body weight, relative weight of the seminal vesicles, vas deferens, and epididymis were not significantly increased (p>0.05) with the considered guava leaves essential oil doses. The testes weights significantly increased (p<0.05) in animals who received 100 and 120 μl/kg body weight compared to control. A significant increase (p<0.05) in sperm concentration, mobility and viability was observed in animals which received the essential oil doses compared to control. Also, the level of proteins and testosterone in serum and testes significantly increased (p<0.05) with the essential oil doses.

Conclusion: Guava leaves essential oil can be used to improve male reproductive performances.
