アレルゲンの産生に関係する身体的特徴は性別のみ

Sex Is The Only Physical Characteristic That Relates To Allergen Production
Sex Is The Only Physical Characteristic That Relates To Allergen Production

毛の長さと色は、Fel d 1 の産生には影響を与えないことが立証された一方、唯一相関関係があると考えられる物理的要因は猫の性別です1～6。 

事実

性別は、Fel d 1の産生と相関関係があることを示す研究があります。


  • 去勢手術を受けていない雄猫は、去勢手術を受けた雄猫や、雌猫（不妊手術の状況と関係なく）と比べて、一般的にFel d 1の産生が多いことが明らかになりました1,6～9。
  • ただし、それぞれの猫のFel d 1量は遺伝子によって変化するため、去勢手術を受けていない雄猫が、高いレベルのFel d 1を産生する雌猫や去勢手術を受けた雄猫よりもFel d 1の産生が少ない可能性もあります1,6,8～11。
