Significance of Sperm viability
Sperm viability refers to the proportion of live spermatozoa in a semen sample, where optimal viability is considered to be 75% or higher. It plays a crucial role in fertility evaluations and can be influenced by various factors, including plant extracts, oxidative stress, and environmental toxins. Measurements of sperm viability help determine male fertility potential and the likelihood of successful fertilization, making it an essential aspect of reproductive health assessments.
