- OBJECTIVE: To study the expression, distribution, and function of thyroid-stimulating hormone receptor (TSHR) and thyroid hormone receptors (TR) alpha1, alpha2, and beta1 in human endometrium. DESIGN: Experimental clinical study. SETTING: University hospital. PATIENT(S): 31 fertile women. INTERVENTION(S): Endometrial biopsy samples obtained throughout the menstrual cycle. MAIN OUTCOME MEASURE(S): Real-time reverse transcriptase polymerase chain reaction, immunohistochemistry and Western blot to study the expression of TSHR, TRalpha1, TRalpha2, and TRbeta1 messenger RNA (mRNA) and proteins in human endometrium. RESULT(S): We found TSHR, TRalpha1, TRalpha2 and TRbeta1 mRNA and proteins expressed in human endometrium. Immunostaining for TSHR in the luminal epithelium and TRalpha1 and beta1 in the glandular and luminal epithelium increased statistically significantly on luteinizing hormone (LH) days 6 to 9, coinciding with appearance of pinopodes. Endometrial stromal and Ishikawa cells expressed mRNA for TSHR, TR, and iodothyronine deiodinases 1-3. After 48 hours, TSH significantly increased leukemia inhibitory factor (LIF) and LIF receptor (LIFR) messenger RNA (mRNA) in endometrial stromal cells, but decreased their expression in Ishikawa cells. Glucose transporter 1 mRNA was up-regulated by TSH in Ishikawa cells. We found that TSH statistically significantly increased secretion of free triiodothyronine (T(3)) and total thyroxin (T(4)) by Ishikawa cells compared with nonstimulated cells. CONCLUSION(S): Thyroid hormones are directly involved in endometrial physiology.

- OBJECTIVE: To evaluate the effects of the immunosuppressant tacrolimus on rejection of a transplanted uterus and on uterine expression of markers of inflammation and implantation. DESIGN: Experimental study. SETTING: University laboratory. ANIMAL(S): Female rats. INTERVENTION(S): Uteri from brown Norway rats were transplanted to Lewis rats, receiving either tacrolimus or no treatment. Sham groups underwent either hemihysterectomy or tacrolimus treatment. MAIN OUTCOME MEASURE(S): Gross morphology, histology, density of T-lymphocytes by immunohistochemistry, and mRNA levels of interleukin (IL)-1α, leukemia inhibitory factor (LIF), galectin-1, CD200, IL-15, interferon-inducible protein-10 (IP-10), and nuclear factor-κB (NF-κB) at 14 days' post-transplantation. RESULT(S): Nontreated uterine grafts showed rejection with necrosis. Sham groups and the tacrolimus-treated transplanted group exhibited normal uterine morphology with low numbers of T-lymphocytes in all uteri except in two out of seven uteri of the tacrolimus-treated transplant group. Uteri of the nontreated transplanted group showed elevated mRNA expression of IL-1α and IP-10 and reduced galectin-1, compared with the tacrolimus-treated transplanted group. There was no difference between any groups concerning uterine expression of LIF, NF-κB, IL-15, and CD200. CONCLUSION(S): Tacrolimus monotherapy suppresses rejection of an allotransplanted uterus and normalizes the expression of IL-1α and IP-10 and prevents T-lymphocyte infiltration.

- he effect of treatment with percutaneous E(2) (100 mu g/24 h) during 2 weeks perimenstrually on the number and severity of menstrual migraine attacks was studied in 27 women in a randomized, placebo-controlled, double-blind, crossover trial. We were not able to demonstrate any difference between E(2) supplementation and placebo on the number or severity of migraine attacks, but both regimens showed significant effects compared with before treatment.

- Objective: To investigate associations between folate-metabolizing gene variations, folate status, and unexplained female infertility. Design: An association study. Setting: Hospital-based IVF unit and university-affiliated reproductive research laboratories. Patient(s): Seventy-one female patients with unexplained infertility. Intervention(s): Blood samples for polymorphism genotyping and homocysteine, vitamin B12, and folate measurements. Main Outcome Measure(s): Allele and genotype frequencies of the following polymorphisms: 5,10-methylenetetra-hydrofolate reductase (MTHFR) 677C/T, 1298A/C, and 1793G/A, folate receptor 1 (FOLR1) 1314G/A, 1816delC, 1841G/A, and 1928C/T, transcobalamin II (TCN2) 776C/G, cystathionase (CTH) 1208G/T and solute carrier family 19, member 1 (SLC19A1) 80G/A, and concentrations of plasma homocysteine, vitamin B12, and serum folate. Result(s): MTHFR genotypes 677CT and 1793GA, as well as 1793 allele A were significantly more frequent among controls than in patients. The common MTHFR wild-type haplotype (677, 1298, 1793) CAG was less prevalent, whereas the rare haplotype CCA was more frequent in the general population than among infertility patients. The frequency of SLC19A1 80G/A genotypes differed significantly between controls and patients and the A allele was more common in the general population than in infertile women. Plasma homocysteine concentrations were influenced by CTH 1208G/T polymorphism among infertile women. Conclusion(s): Polymorphisms in folate pathway genes could be one reason for fertility complications in some women with unexplained infertility. (Fertil Steril (R) 2010;94:130-7.

- OBJECTIVE: To see if progesterone support has a beneficial effect on live birth rate after frozen embryo transfer in natural cycles. DESIGN: Prospective randomized controlled trial. SETTING: University-based hospital. SUBJECT(S): Four hundred thirty-five women undergoing embryo transfer in natural cycles. INTERVENTION(S): The women received either vaginal progesterone, 400 mg twice a day from the day of embryo transfer in natural cycles, or no progesterone support. MAIN OUTCOME MEASURE(S): Live birth rate, biochemical pregnancy rate, pregnancy rate, and spontaneous abortion rate. RESULT(S): Live birth rate were significantly greater in women receiving vaginal progesterone as luteal phase support after frozen-thawed embryo transfer in natural cycles compared with those who did not take progesterone. There were no differences in biochemical pregnancy rate, pregnancy rate, or spontaneous abortion rate. CONCLUSION(S): Progesterone supplementation improves live birth rate after embryo transfer in natural cycles.

- OBJECTIVE: To study the concentrations of vascular endothelial growth factor A (VEGF-A), soluble vascular endothelial growth factor receptors-1 and -2 (sVEGFR-1 and -2), angiogenin, and angiopoietin-2 (Ang-2) in serum and peritoneal fluid from healthy controls and women with advanced endometriosis. Further, we addressed the question of whether surgical removal of endometriotic lesions was associated with normalization of the serum concentrations of the same markers. DESIGN: Patients with endometriosis before and after surgery were compared with control patients. SETTING: University Hospital. PATIENT(S): Twenty-one healthy controls and 32 women with advanced endometriosis. INTERVENTION(S): In women with endometriosis we performed surgical removal of endometriotic lesions using laparoscopy. MAIN OUTCOME MEASURE(S): Data on serum and peritoneal fluid concentrations of selected markers in healthy controls and women with endometriosis before surgery and in serum 5 to 7 days after surgery. RESULT(S): Women with endometriosis had elevated levels of VEGF-A, sVEGFR-1, and Ang-2 in serum and all studied markers in peritoneal fluid compared with healthy controls. Surgical removal of endometriotic lesions resulted in decreased serum levels of pro-angiogenic VEGF-A and increased levels of sVEGFR-2 that negatively regulates the action of VEGF. CONCLUSION(S): Women with advanced endometriosis have serum and peritoneal fluid concentrations of several factors involved in the regulation of angiogenesis that differ from those in healthy women, and these changes at least partly normalize within a week after surgical removal of the endometriotic lesions.

Spontaneous pregnancies occurred in 40%, mainly in women with 45,X/46,XX mosaicism, and oocyte donation in 53% where miscarriages were less frequent, odds ratio 0.43 (95% confidence interval 0.17-1.04).
