Possibly one of the Khuriya Muriya Islands in the Arabian Sea
The Travels of Marco Polo (4 books) written by Rustichello da Pisa in 1300 century describes the legendary adventures of Marco polo in Asia between 1276 and 1291. Rustichello's book is based on M. Polo's verbal stories while they were together in imprisoned in Genoa. According to his journeys M.Polo found 2 mysterious islands south Of Kesmacoran (a coastal strip south of Modern Pakistan) and named them Isle of Males (because of the men who dwelled there for 9 months alone without their wives ) and Isle of Females (where respectively women lived along without their husbands for 9 months.
Possibly a fable because no islands exist in the position indicated by Polo if "south of Kesmacoran," but if we take his indication of "half-way between Mekran and Socotra," the Khuriya Muriya Islands on the Arabian coast, accordingly to some scholars could be possibly those mythological Male and Female Isles, as they would be nearer than any others.
