In: Mansoura University Journal of Animal and Poultry Production 2023.v.14(2)Summary: Studying aims to evaluate sperm characteristics using aqueous extract of maca added to ram semen extender. Five media of ram semen extenders as M0, M1, M2, M3 and M4 contained different levels of aqueous extract of maca at 0, 5, 10, 20 and 40 μg/mL respectively, were storage at 5°C for 5th days,. Then, sperm characteristics as progressive sperm motility, livability, abnormality and intact acrosome and lipid peroxidation (LPO) concentration were estimated. Also, a fertility trial using forty ewes (n=20 in each) were inseminated by M0 (as control) and M3 (as the best sperm parameters). The aqueous extract of maca 20 μg/mL improved previous sperm characteristics and reduced both abnormal sperm and lipid peroxidation (LPO) compared with other extenders during storage at 5°C for 5th days. Also, an improvement observed in total pregnancy rate of ewes using M3 (79.17%) compared with M0 (65.38%) after chilling at 5°C for 2nd days. The results indicate that the aqueous extract of maca maintains spermatozoa characteristics during chilling at 5oC for 5th days especially 20μg/mL which maintains fertile ability after the 2nd days of chilling. Keywords: Maca, semen extender, preservation, fertility.

Studying aims to evaluate sperm characteristics using aqueous extract of maca added to ram semen
extender. Five media of ram semen extenders as M0, M1, M2, M3 and M4 contained different levels of
aqueous extract of maca at 0, 5, 10, 20 and 40 μg/mL respectively, were storage at 5°C for 5th days,. Then,
sperm characteristics as progressive sperm motility, livability, abnormality and intact acrosome and lipid
peroxidation (LPO) concentration were estimated. Also, a fertility trial using forty ewes (n=20 in each)
were inseminated by M0 (as control) and M3 (as the best sperm parameters). The aqueous extract of maca
20 μg/mL improved previous sperm characteristics and reduced both abnormal sperm and lipid
peroxidation (LPO) compared with other extenders during storage at 5°C for 5th days. Also, an
improvement observed in total pregnancy rate of ewes using M3 (79.17%) compared with M0 (65.38%)

spermatozoa characteristics during chilling at 5oC for 5th days especially 20μg/mL which maintains fertile
