Sacred Sperm

an hour-long documentary ... gives the viewer a rare peek into private ultra-Orthodox lives ...

The reproductive organ is called the 'covenant.' Spilling one's seed is called 'damaging the covenant.' And abstaining from masturbation is called 'guarding the covenant.
While other world religions such as Roman Catholicism take a similarly dim view of masturbation and premarital sex, the film makes clear how much more ultra-rigorous the ultra-Orthodox Jews are.
