we know that extremely high temperatures AND pressures are needed over come the electrostatic repulsion between hydrogen nuclei(for e.g.) in order to fuse them together to form a helium nuclues.
my question is, is an extremely high-pressure and low-temperature environment sufficient enough for fusion to take place? or do both of them need to be high?

The fact is, by having extremely high pressures, you automatically get very high temperatures.
It's possible to have very high temperatures without a very high pressure, but not vice versa, so no, they both have to be high.

Unless you have a tame neutron star or black hole to hand, there's no way to get the nuclei close enough together without a high temperature.

so in most circumstances it is high both right?
