Intrinsic pacemaker activity and propulsive forces provided by the myosalpinx are necessary for egg and embryo transport in the oviduct.

Abstract

Oviducts or fallopian tubes are essential for normal fertilization and development of the early embryo; however, their functions are still poorly understood. Oviducts facilitate several physiological processes including (i) transport of the ovum from the ovary to the site of fertilization [1], (ii) aiding the transport of spermatozoa to the site of fertilization [2], (iii) providing a suitable environment for ova and protection from mechanical damage [3], (iv) the maintenance of viability of ova [3], and (v) timely transport of the early embryo to the uterus for implantation [4]. Pathophysiological conditions that disrupt the normal functions of the oviduct often lead to serious health problems, including infertility, ectopic pregnancy, failed early embryonic development, and subsequent loss of embryos. Thus, the oviduct is essential for normal female fertility. In a recent study by Bianchi et al. [5], the authors...
