CAMKK2 and oligospermia: Recent research has indicated that reduced METTL14 levels and increased ALKBH5 levels affect calcium/calmodulin-dependent protein kinase 2 (CAMKK2) mRNA stability and the translation of protein phosphatase magnesium-dependent 1A (PPM1A), and then activate the adenosine-5-monophosphate-activated protein kinase (AMPK) and the active regulator of autophagy ULK1 complex to initiate autophagy which stimulates testosterone production, thus avoiding oligospermia.104
