In rat testis, billions of sperm are produced to increase the chances of successful fertilization. The high quantity compensates for factors such as sperm competition and the challenges of reaching and fertilizing an egg. Additionally, only a small fraction of sperm will survive the journey through the female reproductive tract, making large-scale production essential for reproductive success. This strategy reflects evolutionary adaptations to enhance the likelihood of passing on genes.
