The Effect of Phenolic Extract of Mint (Mentha spicata) in the Fertility of Male Laboratory Mice.

Abstract

The current study was conducted to investigate the effect of the phenolic extract of the Mentha spicata plant on the fertility of laboratory mice. The phenolic compounds were extracted using the Reflex condenser from the leaves of the Mentha spicata plant, and it was chemically detected. In the current study,)Albino Mice of the musculus Mus type was used at an age ranging between (12-11) months. The group was randomly divided into three groups. The control group was injected with a physiological solution (0.9% NaCl), the second group was injected with the phenolic extract of the Mentha spicata plant at (100 mg/kg) concentration, and the third group was injected by concentration (200 mg/kg) from the phenolic extract of the Mentha spicata. The phenols were dissolved in a physiological solution (0.9% NaCl), and all individuals of these groups were injected through the peritoneal membrane I.P. at a rate of 0.5 ml per animal per day for 30 days. The phenolic extract of Mentha spicata leaves caused a significant decrease (P<0.05) in the level of Testosterone and Luteinizing hormone (ng/ml) in the blood serum of the first and second treatment group when compared with the control group. The study also indicates a significant decrease (P<0.05) in the concentration of Follicle-Stimulating Hormone in the third treatment group compared with its level in the control group. At the same time, there were no significant changes (P<0.05) for the second treatment group compared with the control group. The average concentration of sperms taken from the caudal epididymis did not change significantly (P<0.05) for both treatments compared to the control group. The percentage of motile sperm decreased significantly (P<0.05) as a result of treatment with the phenolic extract of Mentha spicata leaves, and this percentage is directly proportional to the increase in the doses used of the extract. Sperm vitality compared to the control group, as for the percentage leading to abnormal sperms, the results showed a significant increase (P<0.05) in the average percentage of abnormal sperms in the caudal epididymis of the second treatment animals when compared with the rates of the first and control groups, while there was no There were no significant changes (P<0.05) in the rate of the first treatment compared to the control. Histologically, the results indicate that treatment with phenolic extract of Mentha spicata leaves caused simple histological changes, represented by a simple vacuole of the interstitial layer between the tubules, slight congestion and partial detachment of the germ cells from the basement membrane with a thick fibrous capsule surrounding the epididymis tubes and congestion of blood vessels. In contrast, the seminal tubules and seminal lumen remained normal. This compared to the control group, which showed the semi- Bionatura http://dx.doi.org/10.21931/RB/CSS/2023.08.03.48 2 niferous tubules, seminal cavity and germ layers commonly with normal spermatozoa stages.
