Sardis Road continues to develop young talent
Tonyrefail-born ex-Wales Under-21 second row Martenko, 23, has signed a development contract at the Ospreys.
Highly rated full-back Morgan Stoddart, 21, offers valuable cover at Stradey as he can also play centre and fly-half.
Hooker Ben Phillips, 24, has also left Konica Minolta Cup winners Ponty for Doncaster RFC, but the club say they will be recruiting in the summer.
We take pride in the talent that we produce and nurture
Pontypridd coach Simon King
"As will always be the case when players leave the club in such circumstances, these boys go with our absolute goodwill," Pontypridd coach Simon King told the club's website.
"We hope they go on to make a mark in the professional game, and whatever success they achieve, we will always be proud that they came to the fore with Pontypridd.
"The ethos of this club remains the same as ever, that we take pride in the talent that we produce and nurture.
"Every player that passes through the system, whether they represent Ponty for one season or 10, will carry the club name with pride."
