“…Functional LH/hCG receptors have been detected in blood vessels of the female genital tract (Lei et al, 1992;Toth et al, 1994;Zięcik et al, 1995), in the umbilical cord (Rao et al, 1996;Wąsowicz et al, 1999), in the mesenteric arteries (Hermsteiner et al, 1999) and in the cavernous sinus-carotid rete vascular complex (Skipor et al, 1999). In pigs, LH/hCG receptors were found in both the uterine and ovarian arteries and veins (Zięcik et al, 1995), while in cows only in the uterine veins but not in the uterine arteries (Shemesh et al, 1997).…”
