Oocytes are exposed to various stressors during in vitro maturation (IVM). Antioxidant supplementation IVM can mitigate oxidative stress. We investigated the effects of supplementing medium with novel flavonoid-enriched antioxidant nanoformulations, namely, EMD-300® and EMP3-H200®, on oocyte analyzed expression stress, apoptosis, pluripotency genes buffalo. Cumulus complexes (COCs) obtained from buffalo ovaries were matured supplemented either or EMP3-H200® at 0.5% 1.0% for 22 h. Following...
Twelve Ossimi rams divided into two groups viz., pre-pubertal (4 to 5 months old, n=6), and post-pubertal (30 48 n=6) were submitted B-mode testicular ultrasonography (US) for evaluation of length, width, thickness volume. Testicular artery was pulsed-wave Doppler examination measure the resistive index (RI) pulsatility (PI) in both groups. width (34.50±3.71mm) volume (58.80±9.98 mm3) showed significantly (P<0.05) higher values ram lambs compared with group (33.60±1.25 mm 56.70±4.07mm3)....
The objective was to determine effects of slow-release melatonin on post-thaw sperm quality in rams exposed mild testicular heat stress (HS; scrotal neck insulation). Twelve yearling Dorset were randomly and equally allocated receive either 36 mg 1 ml corn oil or injected subcutaneously (SQ); 15 day later, all had HS for 96 h (start = start Week 0). Semen collected before once weekly from Weeks 7, extended Steridyl CSS One Step, held at 5°C ~3 h, loaded into 0.5 straws, 5 cm above liquid...
Subfertility is a multifactorial disorder that affects the rabbit production industry. However, subfertility may be treated by using simple intervention such as vitamin supplementation. Vitamin E and selenium (Se) are potent antioxidants protect male reproductive system. The aim of this study to determine effects Se on testicular size, semen quality freezability, antioxidant activity, testosterone levels, fertility in subfertile rabbits. Twenty-one New Zealand rabbits were classified based...
Heat stress (HS) disrupts testicular homeostasis because of oxidative stress. N-acetylcysteine (NAC) is a thiol compound with antioxidants, anti-inflammatory and anti-apoptotic properties. As sequel, this research aimed to assess the ameliorative effects NAC supplementation on reproductive performance goat bucks kept under environmental HS. Primarily, Doppler examination as well semen collection evaluation were conducted 12 mature for 2 weeks (W) pre-heat control (W1 W2) during winter...
Abstract Letrozole (LTZ) is an aromatase inhibitor that limits estrogen (E2) production and increases testosterone (T) levels. This research aimed to examine the impact of a single dose LTZ on testicular hemodynamics, ejaculation time, semen quality in goats under heat stress (HS). Therefore, Doppler examination evaluation were performed twelve mature bucks for two weeks (W-1, W-2) as pre-heat control during winter. Then summer HS subjected examination, evaluation, hormonal analysis (T, E2,...

Increasing evidence of sperm RNA's role in fertilization and embryonic development has provided impetus for its isolation thorough characterization. Sperm are considered tough-to-lyse cells due to the compact condensed DNA heads. Lack consensus among bovine RNA protocols introduces experimental variability transcriptome studies. Here, we describe an optimized method total from using TRIzol reagent. This study critically investigated effects various lysis conditions on isolation. suspended...
