Purpose We evaluate the effect of stem cells to induce endometrial proliferation and angiogenesis on Asherman Syndrome (AS). Methods The experimental study was performed in stemcell research laboratory. Forty Wistar-Albino rats were divided according to groups. In group1 (n=10) to establish the model; trichloroacetic acid was injected to right uterine horn. Two weeks later, intrauterine synechia was confirmed. In group2 (n=10), 2 weeks later, 2×106 mesenchymal stem cells (MSC) were injected into right uterine horn followed by three intraperitoneal injections of MSCs. In group3 (n=10), daily oral estrogen was initiated on the second week. In group4 (n=10), MSC injections and oral estrogen was given together. The amount of fibrosis, vascularisation, inflammation and immunohistochemical staining with vascular endothelial growth factor (VEGF), proliferating cell nuclear antigen (PCNA) and Ki-67 were evaluated in the uterine tissues.

Thyroid auto-immunity (TAI) has been implicated as the most common cause of hypothyroidism in general population, especially in women. Many studies revealed that increased infertility incidences with TAI. The aim of the present article was to evaluate the effect of thyroid auto-antibody (TAA) positivity on embryological parameters, IVF-outcome and endometrial volume (EnV) in infertile patients who were applied for routine artificial reproductive technologies (ART) programme. This study included prospective, sequential, cross-sectional analyses of parameters obtained from 69 patients with unexplained infertility. It was the first ART application of patients. Patients were homogenous for age, body mass index, basal hormone measurements and underwent same ovulation induction protocol. They were evaluated for thyroid hormone profile and TAAs and divided into three groups; TAA negative group (n = 31), TAA positive group (n = 23) and TAA positive and euthyroid with medication group (n = 15). There were no differences among groups for the number of Grade-1 and Grade-2 embryos, distribution of embryo-grades, number of oocytes retrieved and fertilised, biochemical pregnancy ratios (PR), EnV and miscarriage ratio. However, the clinical PR was significantly lower in the TAA positive group (p = 0.024). In conclusion, the embryo grades and EnV did not differ among groups. But the clinical PR differs and the anti-thyroid peroxides positivity, above the cut-off point, affects the clinical PR.

Mosaic embryos have the potential to implant and develop into healthy babies. The transfer of mosaic embryos is now considered to be a possible option for women undergoing ART with preimplantation genetic testing for aneuploidies and in the absence of euploid embryos, particularly those with diminished ovarian reserve and/or advanced maternal age. It can aid in avoiding the discard of potentially viable embryos, which might otherwise result in healthy babies. In over 500 studies on mosaicism, there have been no reports of mosaicism in babies born following the transfer of mosaic embryos. Here, we present a case report of a 39-year-old woman with diminished ovarian reserve with only one blastocyst available for trophectoderm biopsy. The transfer of the embryo, which showed 35% mosaicism of monosomy 2, resulted in pregnancy. Amniocentesis revealed a mosaic trisomic mos46,XX(98)/47,XX,+2(2) karyotype. There were no pathological findings in detailed ultrasonography, and the fetus showed a normal fetal growth with no evidence of intrauterine growth retardation. A healthy female baby was born at Week 37. The peripheral blood chromosome analysis validated with fluorescence in situ hybridization showed 2% mosaic monosomy 2 [mos45,XX,-2(2)/46,XX(98)]. This is the first reported case of true fetal mosaicism resulting in a live birth following the transfer of a known mosaic embryo. Worldwide, prenatal diagnosis has shown the depletion of mosaicism in embryos transferred after they have been reported as mosaics. Our case demonstrates the need for close prenatal monitoring and diagnosis by early amniocentesis, preferably at >14 weeks gestation.

The effect of ISSC and early breastfeeding on mothers was documented for the first time in this study. Our results demonstrated ISSC and early breastfeeding during C/S reduce maternal oxidative stress.
