    Objective: To study the morphometric features of the placenta in Mongolian women with normal and post-term pregnancy in a comparative aspect.Materials and Method: The material for the study was the placenta taken after childbirth from 366 mothers with post-term pregnancies and 695 mothers with normal pregnancies who gave birth in 2017-2018.Morphometric measurement methods were used.For statistical processing of the results obtained, the statistical data analysis package SPSS 23 (IBM) was used.Results: The length of the placenta in women with normal pregnancy was 18.518 ± 1.468 cm, and with post-term pregnancy 19.485 ± 1.824 cm (t = 8.75), (p < 0.001).In women with normal pregnancy, the width of the placenta was 18.150 ± 1.565 cm, and in women with post-term pregnancy, 18.982 ± 1.897 cm (t = 7.20), (p < 0.001).The thickness of the placenta in women with normal pregnancy was 1.997 ± 0.388 cm, in women with post-term pregnancy 2.005 ± 0.432 cm (t = 0.30).The average weight of the placenta was 628.45 ± 86.298 g in women with normal pregnancy, and 721.21 ± 118.166 g in women with post-term pregnancy (t = 13.27),(p < 0.001).The average weight of a newborn was 3444.73 ± 267.766 g in the group with normal pregnancy, and 4094.39 ± 302.624 g in the group with post-term pregnancy, (p = 0.000).The placental-fetal ratio was 0.183 ± 0.00099 in the group with normal pregnancy, and 0.176 ± 0.00157 in the group with post-term pregnancy, (t = 3.77), (p < 0.001).Conclusion: The average values of the morphometric parameters of the placenta during post-term and normal pregnancy have a difference, being within the normal range.As the gestational age increases, the length, width, thickness, and weight of the placenta increase in different ways.

    Objective: In this study we aimed to evaluate the administration efficiency of first-line drugs such as clomiphene citrate (CC), letrozole (L), and the gonadotropin follicle stimulating hormone (FSH) to be used in ovulation induction for intra uterine induction (IUI) in Mongolian patients. Methods: In this prospective single center study we recruited 158 infertile women with polycystic ovarian syndrome (PCOS). Results: In the FSH group, 15 patients (31.2 %) had mycoplasma. On the other hand, the group CC and the L group had a significantly higher number of pregnancies compared than the FSH group. Moreover, there was a trend for an increasing volume of menstruation in the CC group. 38.6 % having a medium volume of menstruation, while 59.6 % had a big volume of menstruation. Stimulation characteristics of patients shows that estradiol on started day (SE2) was significantly higher in the FSH group (768.91 ± 575.64), while it was 523.66 ± 435.84 and 419.36 ± 326.30 in the CC and the L groups, respectively. Conclusions: A minimal stimulation protocol using FSH, CC and L separately was done in Mongolian women with polycystic ovarian syndrome (PCOS). Clinical pregnancy rates were 1.46 ± 0.50 in the FSH group, 1.35 ± 0.48 in CC group, and 1.38 ± 0.49 in L group.
