The aim of the presented study is to determine the effect of different sperm parameters on the pregnancy rate of intrauterine insemination (IUI) cycles in women with favourable fertility characteristics treated for infertility. Medical records of 212 infertile couples who had undergone a total of 253 cycles were reviewed retrospectively. Inclusion criteria for women were age <35 years, antral follicle count >5, FSH <15 IU/ml, and at least one patent tube documented by HSG or laparoscopy. Clinical pregnancy rates were achieved as 15.8% per cycle, and 18.8% per couple. Woman's age, partner's age, total number of motile sperm (TMS) and motility, significantly influenced pregnancy rate. Pregnancy rate was the highest when women were aged <25 and TMS >10 × 10(6). Partner's age significantly affected the pregnancy rate per cycle in women aged <30 years and TMS >10 × 10(6). Woman's age (OR: 5.4 95% CI: 1.2-24.3) and TMS (OR: 0.06 95% CI: 0.003-0.89) were predictor variables as regards to pregnancy. Pregnancy rate was the highest in IUI cycles when woman was <25 years old, TMS was >10 × 10(6), and morphology was >4%. Male age was found to be another determining factor for IUI success, even if they had a normal spermiogram.

BackgroundEndometrial preparation with hormone replacement therapy (HRT) is the preferred regimen for clinicians due to the opportunity to schedule the day of embryo transfer and for patients due to the requirement of fewer visits for frozen-warmed embryo transfers (FET). The increasing number of FETs raises the question of the serum P levels required to optimize the pregnancy outcome on the embryo transfer day.MethodsThis prospective cohort study includes patients who underwent single euploid FET. All patients received HRT with oestradiol valerate (EV) and 100 mg of intramuscular (IM) progesterone (P). FET was scheduled 117–120 h after the first IM administration of 100 mg P. The serum P level was analyzed 1 h before the embryo transfer (ET). In all cycles, only embryos that were biopsied on day 5 were utilized for FET. Next generation sequencing (NGS) was used for comprehensive chromosomal analysis.ResultsOverall, the ongoing pregnancy rate (OPR) was 58.9% (99/168). Data were then categorized according to the presence (Group I; n = 99) or the absence (Group II; n = 69) of an ongoing pregnancy. No significant differences regarding, female age, body mass index (BMI), number of previous miscarriages, number of previous live birth, sperm concentration, number of oocytes retrieved, number of mature oocytes (MII), rate of fertilized oocytes with two pronuclei (2PN), trophectoderm score, inner cell mass (ICM) score, endometrial thickness (mm), oestrodiol (E2) and P levels prior to IM P administration were found between two groups. The P levels on the day of ET (ng/ml) were significantly higher in Group I (28 (5.6–76.4) vs 16.4 (7.4–60) p = 0.039). The P level on the day of ET was a predictor of a higher OPR (p < 0.001 OR: 1.033 95%CI [1.009–1.056]) after multivariate analysis. The ROC curve showed a significant predictive value of serum P levels on the day of ET for OPR, with an AUC (95%CI) = 0.716 (0.637–0.795). The optimal cut-off value for prediction of the OPR was a P level of 20.6 ng/ml (71.7% sensitivity, 56.5% specificity).ConclusionsThe present study suggests a minimum threshold of the serum P value on the day of ET that needs to be reached in HRT cycles to optimize the clinical outcome. Individualization of the P dosage should be evaluated in further studies.

Citalopram is an effective alternative treatment option for patients who do not want to take HT for the alleviation of climacteric symptoms. Adjuvant treatment with a selective serotonin reuptake inhibitor increases the effectiveness of HT for the treatment of climacteric symptoms in women who had responded inadequately to HT.

ABSTRACT:The aim of this study was to evaluate the effect of strontium ranelate (SrR) on fracture healing in the osteoporotic rat model. Forty female Sprague-Dawley rats aged 3 months were enrolled in the study. Osteoporosis was induced by bilateral ovariectomy and subsequent daily heparin injection started 1 week after surgery and lasted for 4 weeks. Osteoporosis was confirmed by a reduction of bone mineral density (BMD). Twenty of the osteoporotic rats were assigned to the SrR group and the remaining 20 to the control group. An open right tibial midshaft transverse fracture was created and then an intramedullary fixation was performed. SrR group was treated by 450 mg/kg/day SrR per oral. Six weeks after surgical induction of fracture, all animals were sacrificed. One animal from each group died after ovariectomy. Two tibiae from the control group failed to unite. SrR-treated group showed higher mechanical strength and fracture stiffness when compared to the control group (p = 0.006, p = 0.001, respectively). SrR-treated group had mature woven bone or predominantly woven bone compared with osteoporotic control group (p = 0.038). SrR-treated group's callus maturity was significantly higher than control group (p = 0.001). SrR is associated with better fracture healing in the osteoporotic rat model.
