The present study was an attempt to understand the sexual dimorphism of the integumentary scent glands of soft-furred fi eld rat Millardia meltada from the perspectives of anatomy, morphology and histology with view to correlate with the sex-specifi c pheromones they produce. The scent gland of male is known as preputial gland, and female, the clitoral gland. The rats, that are agricultural pests were fi eld caught, the glands of males and females of almost identical size were dissected out, and subjected to gravimetric, morphometric and histological analyses. Both glands are yellowish-brown, pear-shaped, and dorsoventrally compressed. The mean weight, length and width of preputial glands are signifi cantly (p < 0.05) larger than that of the clitoral glands. The preputial gland is composed of sebaceous glandular lobules and apocrine glandular lobules whereas the clitoral gland is formed only of sebaceous glandular lobules. The sebaceous glandular lobules of both preputial and clitoral glands are fi lled with a wax-like material. Thus, the scent glands of the soft-furred male fi eld rats exhibit sexual dimorphism in respect histoarchitecture of the glands and the nature of the secretory material. This sexual dimorphism of the scent glands may refl ect control by male and female sex hormones impinging on specifi c roles as sex attractant pheromones.
