Yoni is the fourth koota — 4 of 36 points that read physical and intimate compatibility, symbolized through 14 animal pairs assigned to the 27 nakshatras.
Yoni means "source" or "womb," and in Ashtakoot matching it's a symbolic system for reading physical attraction, intimate compatibility, and instinctive temperament between two partners — expressed through 14 animal archetypes, each assigned to specific nakshatras. It's worth 4 of the 36 total points, derived from each partner's birth nakshatra.
Every nakshatra is paired with one of 14 animals, each carrying a male and female form (e.g. horse/mare, elephant/she-elephant) that further nuances the reading. The animals span a wide temperament range — Ashwa (horse) and Gaja (elephant) read as strong and dignified, Mushaka (rat) and Mesha (sheep) as gentler, Simha (lion) and Vyaghra (tiger) as bold or dominant, and pairs like Sarpa (serpent) and Nakula (mongoose), or Gau (cow) and Vyaghra (tiger), are classically read as natural enemies.
A low or zero Yoni score is classically read as a sign that the two partners' instinctive, physical temperaments may pull in different directions — not a prediction of an unhappy marriage on its own, but one input astrologers weigh alongside Graha Maitri (emotional compatibility) and the heavier-weighted Nadi and Gana kootas before forming an overall view.

No — it's a symbolic system using 14 animal archetypes to read physical attraction and instinctive temperament, not a literal or medical assessment.
That's the strongest possible result — the full 4 points, read as strong physical and instinctive compatibility.
Classical pairs include cow–tiger, serpent–mongoose, cat–rat, and a few others — combinations traditionally seen as naturally opposed instincts.
It's 4 of 36 points — meaningful but not decisive on its own. It's read alongside Graha Maitri, Gana and Nadi, which together carry far more weight.
