Saiz zakar manusia
Saiz zakar manusia berbeza-beza mengikut beberapa ukuran, termasuk panjang dan lilitan apabila lembik dan tegak. Selain kebolehubahan semula jadi zakar manusia secara amnya, terdapat faktor yang membawa kepada variasi kecil pada lelaki tertentu, seperti tahap keghairahan, masa dalam sehari, suhu bilik, tahap kebimbangan, aktiviti sukan dan kekerapan aktiviti seksual. Berbanding dengan primata lain, termasuk contoh besar seperti gorila, zakar manusia paling tebal, kedua-duanya dari segi mutlak dan relatif kepada seluruh badan.[1][2]
