Abstract

One factor that affects frozen semen characteristics is bull age. Increasing age induces changes in sperm that reduce frozen semen quality. This study aimed to evaluate the frozen semen characteristics of Bali bulls aged 3, 8, and 13 years. Frozen semen was derived from fresh semen with sperm motility > 70%. The frozen semen characteristics tested included motility, viability, plasma membrane integrity, acrosome integrity, and sperm abnormalities. Sperm motility was analyzed by computer-assisted sperm analysis (CASA). Viability was assessed using eosin-nigrosin staining; plasma membrane integrity was assessed using the hypoosmotic swelling test (HOST); acrosome integrity was assessed using Giemsa staining; and sperm abnormalities were assessed using Williams staining. The plasma membrane integrity of the 13-year-old group was significantly lower (P < 0.05) than that of the younger age groups. However, there were no significant differences (P > 0.05) in the other parameters. We conclude that age affects the integrity of the sperm plasma membrane in frozen semen from Bali bulls.

Abstract

Physalis angulata L. (ciplukan) is traditionally used as an herbal remedy with anticancer and antioxidant properties. At the same time, busulfan, a chemotherapy alkylating agent, causes gonadotoxicity and oxidative stress that impair female reproduction. This study aimed to evaluate the effect of P. angulata on reproductive function after busulfan administration in female rats. Twenty-five 6-week-old female rats were randomly divided into: Group I (control), Group II (busulfan only), Group III (P. angulata only), Group IV (busulfan followed by P. angulata after 14 days), and Group V (busulfan and P. angulata administered for 28 days). FSHR and LHR expression in the ovaries and MDA levels in the ovaries and uterus were measured to assess reproductive changes. Busulfan showed no significant effect on FSHR and LHR, whereas P. angulata induced downregulation, suggesting a potential negative feedback mechanism on ovarian receptors. Ovarian MDA showed a decreasing trend with combined treatments, while uterine MDA peaked after busulfan but declined markedly with P. angulata, indicating its role in alleviating oxidative stress. In conclusion, P. angulata may modulate hormonal balance in rat ovaries and decrease oxidative stress in the uterus after busulfan treatment.

Abstract

Penyimpanan semen cair berpotensi meningkatkan pembentukan radikal bebas dan stres oksidatif, yang menyebabkan kerusakan membran plasma spermatozoa dan penurunan kualitas semen. Glutation merupakan antioksidan yang mampu menetralkan radikal bebas dan mengurangi kerusakan oksidatif, sehingga berpotensi menjaga kualitas spermatozoa selama penyimpanan. Penelitian ini bertujuan mengevaluasi pengaruh penambahan glutation terhadap kualitas semen cair domba dalam pengencer komersial berbasis tris kuning telur. Semen segar dengan motilitas ≥70% diencerkan dengan penambahan glutation pada konsentrasi 0 mM (GSH-0), 2 mM (GSH-2), dan 4 mM (GSH-4), kemudian disimpan pada suhu 4  selama enam hari. Evaluasi dilakukan setiap 24 jam terhadap motilitas, viabilitas, keutuhan membran plasma (MPU), dan abnormalitas spermatozoa. Hasil hari keenam menunjukkan bahwa GSH-4 memberikan hasil terbaik, dengan motilitas 64,00 ± 2,24%, viabilitas 84,95 ± 1,12%, MPU 85,93 ± 0,46%, dan abnormalitas 9,47 ± 0,66%. Berdasarkan hasil penelitian ini dapat disimpulkan bahwa penambahan glutation 4 mM efektif dalam mempertahankan kualitas semen cair domba selama pada suhu
