Materials and Methods: 1038 patients who applied to our IVF clinic for semen analysis or for infertility treatment were included in the study. The participants were divided into three age categories as follows: 680 participants (65.5%) aged 22-30, 139 participants (13.4%) aged 31-45 years, and 219 participants (21.1%) aged ≥45 years. Demographic and baseline clinical characteristics were recorded. The variables considered in this study were age and the following semen parameters: volume (ml); sperm concentration (millions/ml); and progressive sperm motility A+B (%). Normal semen values were defined based on the WHO criteria (World Health Organization, 2010). Results: The mean age of the participants was 33.1(± 4.8). The mean BMI of the participants was 24.1(± 2.8). The mean semen volume was 3.3 (± 1.5), the mean semen concentration was 43.6 (± 31.7), and the mean progressive sperm motility was 43.6 (± 10.1). There was a moderate negative correlation between paternal age and semen volume (r=-0.13) and sperm motility (r=-0.32), while there was a moderate positive correlation between paternal age and sperm concentration (r=0.24). The proportion of likelihood ratio measured between semen volume, sperm concentration, sperm motility and age was found to be 1 in patients between the ages of 22-30. The 22-30 age group does not have a decreasing or increasing effect on semen volume (OR: 1), sperm concentration (OR: 1) and motility (OR: 1). Regression analysis of patients in the 31-45 age group revealed no change in semen volume (OR: 0.99, 95% CI: 0.43-2.3, p <0.9), but an increase in sperm concentration (OR: 1.74, 95% CI: 1.13-2.7, p <0.01), and decreased sperm motility (OR: 0.28, 95% CI: 0.16-0.47, p <0.00). In the regression analysis of participants over the age of 45, semen volume (OR: 0.31, 95% CI: 0.19-0.53, p <0.00) and sperm motility (OR: 0.05, 95% CI: 0.03-0.08, p <0.00) decreased with age. No change was detected in the concentration (OR: 0.87, 95% CI: 0.63- 1.2, p <0.3). Conclusion: With increasing male age, semen volume and sperm motility begin to decrease. However, a significant decrease in sperm concentration does not occur until the age of 45.","PeriodicalId":12828,"journal":{"name":"Gynecology & reproductive health","volume":"12 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72786296","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: Five hundreds women undergoing cryopreserved-thawed embryo transfer were included in the study. These patients had a total of 500 embryos frozen on day 3 (n = 200), day 4 (n = 100), day 5 (n = 150) and day 6 (n = 50). Artificial endometrial preparation was successfully performed in all participants. If the endometrial thickness reached a minimum of 8 mm or in the presence of a triple-line view, the patients were divided into four different groups and each group into two subgroups according to the estimated duration of progesterone treatment to be used. Group 1 (n = 200): This group consisted of patients with day 3 embryo transfer. While 100 of 200 patients received embryo transfer after 3 days of progesterone treatment, the remaining 100 patients received embryo transfer after 4 days of progesterone treatment. Group 2 (n = 100): This group consisted of patients who underwent day 4 embryo transfer. While 50 of 100 patients had embryo transfer after 4 days of progesterone treatment, the remaining 50 patients received embryo transfer after 5 days of progesterone treatment. Group 3 (n = 150): This group consisted of patients who received day 5 embryo transfer.

Endometrial HOXA-10 mRNA expression, a well-characterized gene essential to endometrial receptivity, was evaluated in PCOS patients whose embryos are planned to be frozen due to the risk of OHSSS. Methods: Twent-five women with PCOS in high risk group for OHSS and age and BMI matched 25 non-PCOS infertile patients were included the study. Five fertile women were accepted as positive control. Following egg collection each group of subject underwent total embryo freezing. After the egg collection, endometrial sampling was performed with a pipella cannula from each gruop of participant and fertile control. Expression levels of HOXA-10 mRNA were determined by RT-PCR. Gene expression results are presented as Ct (cycle threshold), ΔCt, and ΔΔCt. Reults: Average ΔCt value of HOXA-10 mRNA in PCOS, non-PCOS and fertile groups were found to 5.88, 6.77, and 7.79 respectively. Compared to endometrial HOXA-10 mRNA levels of fertile cases, the HOXA-10 mRNA levels of the patients in the PCOS group were found to be significantly lower (ΔCt 7.79 vs. ΔCt 5.88, p<0.002). Similarly, endometrial HOXA-10 mRNA levels in the non-PCOS control group were significantly lower than the HOXA-10 mRNA levels in the fertile group (ΔCt 6.77 vs. ΔCt 7.79, p<0.001).

It is extremely rare in pregnancy, but when it occurs, the respiratory compromise worsens and anaesthesia becomes challenging. There is no consensus yet on the choice of anaesthesia. We present a 29-year-old, 32-week parturient with MND who presented with severe dyspnea, orthopnea and was diagnosed with severe respiratory distress. She was admitted into ICU and given anticoagulant and steroid therapy. Sequential mini-dose combined spinal-epidural anaesthesia (CSE) was given and surgery performed in the semi-sitting position successfully. There was no deterioration of symptoms post anaesthesia.

With the assistance of ART, they are finally able to “carry a baby to term.” This is wonderful for first-time parents. This case report involves a woman who delivered a premature baby weighing 1,520 g at 30+5 weeks using ART and her family care experience. During the period of care from October 23, 2016 to December 9, 2016, data were collected on this case through systemic assessment, clinical observation, and parental interview. Problems including gas exchange disorder, caregiver role tension, and the potential risk of parent-child attachment disorder were identified. In addition to providing appropriate medical care to maintain stable vital signs, we hoped to reduce the occurrence of comorbidities through a complete nursing assessment and comprehensive developmental care. We also attempted to build trust and to reduce parental anxiety and stress by providing relevant medical information and psychological support through active and proactive nursing care. The performance of “kangaroo care” with stable vital signs enhances parent-child attachment and a sense of involvement in the ongoing care of the infant. This strengthens the mother’s motivation and self-confidence in her caregiving role, enhances her sense of accomplishment as a mother, and promotes the growth and development of the infant after returning home. The weight of the infant reached 2,430 g before discharge. Before discharge, the mother was able to cite at least two caregiving skills and her eyes were no longer red from sobbing. We hoped that the parent-child attachment was well developed and that “kangaroo care” will assist the mother to face the future with a positive attitude after returning home. This article can be used as reference for nursing practitioners to improve the quality of care for premature babies.","PeriodicalId":12828,"journal":{"name":"Gynecology & reproductive health","volume":"25 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83388381","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, training of “boda-boda” (motor-cycle) riders in Busoga Region in Uganda was conducted to determine its effect on health facility-based deliveries. The study was a non-randomized control trial with intervention and control groups from selected health centers and communities in Busoga Region. Interventions included the training of boda-boda riders for 5 days to give them knowledge; with a six months follow-up to determine the impact of training. Questionnaires, interviews and focus group discussions were used to collect quantitative and qualitative data. Descriptive statistical analysis was computed for the quantitative data and thematic analysis for qualitative data. Findings revealed improved knowledge of boda-boda riders on maternal referrals from 49.1% to 79.0% in the intervention arm compared to 43.8% to 45.2% in the control arm. Use of boda-boda transport by mothers improved from 0% to 70.5% in the intervention arm compared to only 0% to 51.2% in the control arm. Also, of the 70.5% of the mothers who used boda-boda transport, 69.4% were transported by trained boda-boda riders and only 30.6% by un-trained boda-boda riders.
