Effects of BSHXR on murine pregnancy and endometrial development. a Uterine morphology on ED8. Arrows point the embryo sites. b Number of embryo implantation sites. ^#P < 0.05 vs. control group, ^*P < 0.05 vs. model group. c Overall observation of the uterus. d Endometrium isolated from the uterus. 1, Control; 2, Control + BSHXR; 3, Model; 4, BSHXR-L; 5, BSHXR-M; 6, BSHXR-H; 7, BSR; 8, HXR. The number of the mice from 1 to 8 were 41–3, 45–2, 48–3, 49–2, 48–4, 49–1, 40–5, 42–2. The first number indicates the number of the cage, and the second number indicates the animal number in each cage. e Weight ratio of endometrium to uterus. Data were represented as mean ± SD. ^####P < 0.0001 vs. control group, ^*P < 0.05 vs. model group
