RESUMO

OBJECTIVE: To compare the effect of microfluiding sperm sorting chip and density gradient methods on ongoing pregnancy rates (PRs) of patients undergoing IUI. DESIGN: Retrospective cohort study. SETTING: Hospital IVF unit. PATIENT(S): Couples with infertility undergoing IUI cycles between 2017 and 2018. INTERVENTION(S): Not applicable. MAIN OUTCOME MEASURE(S): Ongoing PRs. RESULT(S): A total of 265 patients were included in the study. Microfluid sperm sorting and density gradient were used to prepare sperm in 133 and 132 patients, respectively. Baseline spermiogram parameters, including volume, concentration, motility, and morphology, were similar between the two groups. Total motile sperm count was lower in the microfluiding sperm sorting group at baseline (35.96 ± 37.69 vs. 70.66 ± 61.65). After sperm preparation sperm motility was higher in the microfluid group (96.34 ± 7.29 vs. 84.42 ± 10.87). Pregnancy rates were 18.04% in the microfluid group and 15.15% in the density gradient group, and ongoing PRs were 15.03% and 9.09%, respectively. After using multivariable logistic regression and controling for confounding factors, there was a significant increase in ongoing PRs in the microfluid sperm sorting group. The adjusted odds ratio for ongoing pregnancy in the microfluid group compared with the density gradient group was 3.49 (95% confidence interval 1.12-10.89). CONCLUSION(S): The microfluid sperm sorting method significantly increased the ongoing PRs compared with the density gradient group in IUI cycles.

RESUMO

OBJECTIVE: Repeated implantation failure (RIF) is a clinical entity affecting many couples undergoing assisted reproductive technology (ART). Various intrauterine pathologies contribute to RIF. Nevertheless, vaginal sonography and hysterosalpingography, which are the common diagnostic tools for the initial follow-up, have limited sensitivities. In this context, we aimed to evaluate the impact of office hysteroscopy (oHS) on live birth rates (LBRs) when performed prior to subsequent ART cycles in women with a history of RIF. MATERIAL AND METHODS: The database of an assisted reproduction center was retrospectively reviewed to detect eligible cases. A total of 363 women out of 2875 admissions were consecutively included in the analysis, of which 119 formed the oHS group and 244 formed the non-oHS group prior to a new ART cycle. Women in the oHS arm were examined during their early follicular phase via a vaginoscopic approach 1-6 months before the beginning of a new cycle. The standard in-vitro fertilization-intracytoplasmic sperm injection (IVF/ICSI) cycle was applied to all the women. RESULTS: In the oHS group (n=119), 61 patients had intrauterine abnormalities, with an overall abnormality rate of 51.2%. Implantation, pregnancy, and LBRs of the groups were statistically similar. LBRs of the women with abnormal oHS findings (15/61, 24.5%), with normal oHS findings (14/58, 24.1%), and without oHS (39/244, 16%) were statistically similar (p=0.41). CONCLUSION: Unrecognized intrauterine pathologies can be easily detected and concurrently treated during oHS with high success rate. However, a beneficial impact depends on the extent of the pathology and thus, routine application to enhance reproductive outcomes is still not warranted.

RESUMO

We present two cases of twin pregnancies without resolution of preeclamptic symptoms after intrauterine death of one twin. CASE 1: A nulliparous woman aged 37 years was referred at 26 weeks of gestation because of arterial hypertension, edema, and growth restriction in one twin. Three weeks later the restricted twin died. During the following three weeks, ultrasound examinations showed a reduced growth velocity of the surviving fetus and reversed umbilical flow. At the end of the 34th week of gestation, cesarean section was performed and a healthy female infant was delivered. CASE 2: A nulliparous woman aged 33 years with a 27-week twin pregnancy was referred because of arterial hypertension and discordant growth. The restricted twin died at 31 weeks of gestation. Following the death, within two weeks the growth of the co-twin started to slow down and reversed end diastolic flow presented. At the end of the 33rd week of gestation, cesarean section was performed and a healthy female infant was delivered.The interesting point of these cases was the secondary effects on the co-twins. During the time after intrauterine deaths of one twin, the surviving fetuses started to show a reduced growth velocity and reversed umbilical flow and mothers had increased blood pressure and proteinuria again. We think that both cases are evidence of late on-set systemic maternal effects (such as systemic maternal endothelial activation and/or systemic maternal inflammatory response) depends on preeclampsia.

RESUMO

OBJECTIVE: To evaluate whether oral contraceptive pill (OCP) therapy has any effects on ovarian stromal blood flow by using pulsed and color Doppler at the end of 3 months follow-up period of OCP-users and non-users with or without polycystic ovary syndrome (PCOS). STUDY DESIGN: 200 patients were included in the study. The patients were designed into four groups as follows; Group 1: PCOS patients that received OCP containing 30 mcg ethinyl estradiol (EE) plus 3mg drospirenone for 3 months (DRP n=50); Group 2: PCOS patients that received no medication (n=50); Group 3: Healthy controls that received OCP (EE plus DRP) (n=50); Group 4: healthy controls that received no medication (n=50). Resistance index (RI) and pulsatility index (PI) of both ovarian arteries, hormonal, anthropometric and biochemical parameters were assessed before and after 3 months. RESULTS: There was a significant increament in RI and PI of both ovarian arteries in healthy controls (Group 3) and in women with PCOS (Group 1) who received OCP (p<0.001). The increment rate in both Doppler parameters were significantly higher in women with PCOS (Group 1) than healthy controls (Group 3) (p<0.001). Whereas RI and PI values of both ovaries remained unchanged in all untreated women with or without PCOS (Groups 2 and 4). CONCLUSION: OCP therapy reduced ovarian vascularization in both PCOS and healthy users after 3 months of therapy and this decrease is especially noticeable in women with PCOS.
