Kahlest was young Worf's ghojmoq on Khitomer. (TNG "Sins of the Father")

*gin'tak* (an advisor so trusted he has been made part of the family) or *ghIntoq could be the male equivalent. He wears a special ring, bearing the crest of the House he has pledged his life to defend. ghIntaq is literally a "battle spear", which could be a metaphor (e.g. my "right hand" in English). Worf said "K'mtar is gin'tak to the House of Mogh". [TNG "Firstborn"]

Though never stated, the elderly Tumek may have been *gin'tak* to the House of Kozak. He continued to work for his widow, Grilka. (DS9 "House of Quark")
