Carvacrol and Thymol Enhance the Quality of Beni Arouss Buck Semen Stored at 4 °C Thanks to Their Antimicrobial Properties.

This study aims to investigate the impact of carvacrol and thymol on the quality of Beni Arouss buck semen stored in skim milk at 4 °C. Ejaculates were collected from eight Beni Arouss bucks weekly for 11 weeks, pooled, and then divided into three equal parts. Samples were diluted to 400 × 10 sperm/mL in skim milk (control) and skim milk supplemented with a single dose of 200 µM carvacrol and thymol each.

Enhancing cryopreserved ram sperm quality at -80 °C with Spirulina platensis and Salvia verbenaca extracts.

This study was conducted in two steps to evaluate the influence of freezing methods and natural extracts on cryopreserved ram sperm quality. Initially, the research compared the effects of two freezing methods: liquid nitrogen (LN2) versus -80 °C, on post-thawed ram semen on total and progressive motilities and velocity parameters. Experiment I revealed no significant differences (P > 0.

Reproductive Enhancement through Phytochemical Characteristics and Biological Activities of Date Palm Pollen: A Comprehensive Review on Potential Mechanism Pathways.

Infertility represents a significant global health challenge affecting both men and women. Despite regular unprotected sexual intercourse, approximately 15% of couples of reproductive age struggle to conceive within 12 months, with 10% of infertility cases attributed to unknown causes worldwide. As a result, numerous studies have turned their attention to exploring the use of natural products for the prevention and treatment of infertility.

Effects of Origanum majorana essential oil and antibiotics on the quality of frozen thawed Beni Arouss buck semen.

This study aims to investigate the effects of Origanum majorana (OM) essential oil (EO) at different concentrations and antibiotics on post-thawed Beni Arouss buck semen quality. Semen collection was performed using artificial vagina from eight Beni Arouss bucks. Ejaculates were pooled, divided into 12 equal aliquots, washed and diluted to 400 × 10 sperm/ml (with 7% of glycerol).

Evaluation of different hormonal treatments on oestral and ovarian responses in Moroccan Beni Arouss goats during anoestrus and breeding season.

The efficacy of eight combinations of fluorogestone acetate (FGA, 20 or 40 mg as intravaginal device during 11 days), equine chorionic gonadotropin (eCG, 300 or 500 UI injected 48 hr before FGA removal) and prostaglandin F (cloprostenol, 0 or 50 μg injected 48 hr before FGA removal) aiming at induction and synchronization of oestrus and ovulation was evaluated during the anoestrus season in spring and during the breeding season in autumn in adult Beni Arouss goats. Oestrous behaviour was recorded between 12 and 60 hr after FGA removal. Blood samplings allowing to assess onset of the pre-ovulatory LH surge and increase of progesterone as sign of an active corpus luteum were performed, respectively, between 20 and 60 hr and 3, 5, 8 and 15 days after FGA removal.

Effect of season on sexual behavior, testicular measurements and seminal characteristics in "Beni arouss" North Moroccan bucks.

Changes in anatomical, behavioural and seminal characteristics were measured throughout the year in seven Beni Arouss bucks maintained at a latitude of 35 °N. Testicular size varied significantly. There were the greatest values during the summer and autumn for scrotal circumference and least in the winter for testicular length.
