Los gametos masculinos, es decir, los espermatozoides, son células haploides que se generan mediante el proceso de espermatogénesis.
En la etapa fetal, las células germinales primordiales llegan al testículo en desarrollo, se diferencian en espermatogonias y se incorporan a los cordones testiculares, en donde se mantienen hasta la pubertad.
Cuando el varón llega a la pubertad, los cordones testiculares, que se encontraban cerrados, se abren y se convierten en túbulos seminíferos. La espermatogénesis, que es la formación de espermatozoides en el testículo, se realiza a lo largo del epitelio de estos túbulos, y consta de 3 fases: proliferativa, meiótica y espermiogénesis.

Natural World: Saving The Panda
Granted exclusive access to the world’s number one panda research centre and reserve at Chengdu, this film follows the life of a mother and cubs from conception through birth and hand-rearing, to play and young adulthood – and the international team that care for them – over the course of 18 months. With archive footage, the film looks back at the extraordinary East-West collaboration that brought giant pandas back from the brink of extinction, and ahead to the radical, controversial and risky next phase: reintroduction into the wild.
