🔬 Researchers identified CCDC89 variants in men with #azoospermia (no sperm in ejaculate) and recreated an equivalent mutation in mice. Mutant mice produced 22% fewer sperm, showing reduced #fertility.

🧬 Male infertility affects over 7% of men worldwide, with genetics playing a significant role. A study led by Aussie researchers has identified the protein CCDC89 as essential for normal #spermmotility.

Study Finds Seasonal Variation in Sperm Motility Across Different Climates A new international study has found that sperm motility, or the ability of sperm to swim effectively, peaks during the summer months and declines in winter. Researchers from the UK, Canada and Denmark analysed semen samples from 15,581 men aged 18 to 45 in Denmark and Florida. Despite the significant climate differences between the two regions, the seasonal pattern was strikingly similar. Sperm motility was consistently highest in June and July and lowest in December and January in both locations. Interestingly, the researchers found no seasonal variation in total sperm concentration or ejaculate volume. This means that while the number of sperm produced and the amount of semen released remained stable throughout the year, the sperm's swimming ability changed depending on the season. Since sperm motility plays a crucial role in successful fertilisation, these seasonal fluctuations could have implications for couples trying to conceive. The study, published in the journal Reproductive Biology and Endocrinology, suggests that factors beyond ambient temperature may influence sperm quality. Even in Florida, where temperatures are warm year-round, sperm motility still followed the same seasonal trend observed in Denmark. According to Professor Allan Pacey from the University of Manchester, who co-authored the research, the findings indicate that temperature alone cannot explain the variation. Researchers note that the optimal temperature for the testes is slightly below core body temperature, around two to four degrees lower than 37°C. Deviations from this range can negatively affect sperm motility. The findings highlight the importance of considering seasonal patterns in fertility assessments and treatments, potentially helping to improve reproductive outcomes.
