Internal fertilization usually implies that a spermatozoon, with intact attributes for zygote formation, passes all hurdles during its transport through the female genitalia and reaches the oocyte. During this journey, millions to billions of other spermatozoa perish. Spermatozoa are highly differentiated motile cells without synthetic capabilities. They generate energy via glycolysis and oxidative phosphorylation to sustain motility and to maintain the stability and functionality of their plasma membrane. In vivo, they spend their short lifespan bathing in female genital tract fluids of different origins, or are in vitro exposed to defined media during diverse sperm handling i.e. extension,...

Motor games are incredibly useful in enhancing education and developing critical skills; they can entertain, produce pleasant emotions, improve moods, and increase the level of relationships. Motor games allow social, emotional, and cognitive development as well as the acquisition of motor skills such as knowledge and mastery of body, postural control and adjustment, and improvement of coordination. However, it is essential to select the appropriate game for each context to achieve the desired learning in all students. Further research on the opportunities, challenges, and future directions of motor games in education is necessary to successfully implement them. The Handbook of Research on Using Motor Games in Teaching and Learning Strategy presents significant advances in motor game education and collects research evidence that uncovers the certainties and testifies to the educational power of motor games in various situations and specific contexts that promote the learning of participants. Covering topics such as emotional physical education and educational mediation, this major reference work is ideal for researchers, academicians, educators, practitioners, and students.
