In 2016, the Louvre was the world's most visited art museum, receiving 7.3 million visitors. The museum is housed in the Louvre Palace, originally built as a fortress in the late 12th to 13th century under Philip II. Remnants of the fortress are visible in the basement of the museum.
The primary sex organ of a male is the testis. The testis is the reproductive gland of males. It produces spermatozoa and the androgens.
The prepuce is primary, erogenous tissue necessary for normal sexual function [ 8 ]. The complex interaction between the protopathic sensitivity of the corpuscular receptor-deficient glans penis [ 42 ] and the corpuscular receptor-rich ridged band of the male prepuce [ 45 ] is required for normal copulatory behaviour.
