More couples are delaying childbearing, which unfortunately can negatively influence the health of their child. Using reproductively old mice at 12 months old, we examined the characteristics of the offspring of older mothers at birth, and then followed them to adulthood and measured markers of adult health, namely growth, glucose tolerance, immune function and behaviour. This study provides insights into how maternal age influences the health and development of their offspring. Image by Macarena B. Gonzalez.

The optimization of sperm freezing and storage program has an important impact on reducing breeding costs, improving reproductive efficiency, overcoming reproductive diseases, and protecting germplasm resources. In this paper, we have included two potential additives, sodium alginate (SA) and bovine serum albumin (BSA), which can effectively improve sperm motility after cryopreservation. This is of great significance for improving the quality of pig semen, improving reproductive ability and the development of modern pig breeding industry. Image by Jing Wang using Figdraw.
