No NELL2, no sperm motility—novel protein is essential for male fertility

No NELL2, no sperm motility—novel protein is essential for male fertility

Newly produced spermatozoa within the testis are not fully functional until they mature in the epididymis, a duct that helps to transport and store sperm. Male infertility may arise from lack of communication between the testis and the epididymis and new research has uncovered a mechanism of this communication.
