The Life Sciences Department at the College of Education for Pure Sciences at the University of Kerbala discussed a master’s thesis entitled (Histological and Immunochemical Study of the Effect of Anabolic Steroids and Lepidium Meyenii Plant Extract in Male White Rats). For the student (Maryam Ahmed Ali), under the supervision of (Prof. Dr. Ashwaq Kazim Obaid). The thesis aimed to test the effectiveness of the aqueous and secondary extract of the maca root herb (Lepidium meyenii) as a protective substance to reduce the toxic effects of the drug oxymethylone on the testicular, epididymal and prostate tissues in male white rats and to study some histological and functional changes. The study also concluded that the oxidative stress caused by oxymethylone negatively affected the fertility of male rats through changes in the normal sperm parameters, which included a decrease in sperm concentration, as well as degenerative tissue changes in the testis, epididymis and prostate, with a decrease in the diameters of the seminiferous tubules and epididymis. The study recommended conducting more studies to clarify the effect of oxymethylone treatment on glands such as the pituitary gland, adrenal gland and thyroid gland due to their relationship to sexual maturation and others after exposure to oxidative stress in the body. In addition to conducting other studies on sports stimulants to diagnose the side effects associated with their use in body weight, organ weights, and physiological and biochemical parameters of the blood. The student received an excellent grade.
