Figure 5: Histoarchitecture of uterine tissues of the control andvaccinated mice obtained at terminal sacrifice and stained withGoldners trichrome (4X). Immunization against GnRH-I found toreduce concentratoion of uterine glands (yellow). In an average10-15 glands per uterine section in Group 2 (b) mice and 08-12glands per section in Group 3 (c) mice was seen. The concentrationof uterine glands (yellow arrow) appeared much higher in Group 1(a, more than 40 glands per section) mice. The endometrium incontrol section (a) was repeatately folded in the lumen (blackarrow) of uterus but were unfolded in Group 2 (b) and Group 3 (c)mice.
