AI Article Synopsis
- The study aimed to evaluate whether using a softer insemination catheter (Wallace) would result in higher pregnancy rates compared to a firmer catheter (Tomcat) during intrauterine insemination (IUI).
- A total of 747 IUI cycles were analyzed, with 372 cycles using the Wallace catheter and 375 cycles using the Tomcat catheter, showing pregnancy rates of 16.4% and 18.1%, respectively.
- The results indicated no significant difference in pregnancy rates between the two catheter types, suggesting that both can be effective when used with a gentle technique.
Article Abstract
Purpose: To determine if a soft insemination catheter increases pregnancy rates.
Methods: Seven hundred forty-seven consecutive intrauterine insemination (IUI) cycles in 364 women in a reproductive endocrinology office between October 1998 and March 2000. Patients with even birth years were inseminated with the Tomcat catheter, and those with odd birth year with the Wallace IUI catheter. Clinical pregnancy rates were compared.
Results: The Wallace catheter group included 180 women for 372 cycles and an overall pregnancy rate of 16.4%. The Tomcat catheter group included 184 women for 375 cycles and an overall pregnancy rate of 18.1%. This difference is not statistically significant (P = 0.61). Potential confounders were accounted for.
Conclusions: When comparing the softer Wallace catheter to the less pliable Tomcat catheter during IUI cycles, there was no significant difference in pregnancy rate when using a standard gentle technique that includes not touching the top of the fundus with the catheter.

Rural-urban disparity in uptaking skilled antenatal care visits by pregnant women in Bangladesh: Zero and One Inflated Poisson regression model.

Department of Statistics, University of Dhaka, Dhaka, Bangladesh.
Background: Utilization of maternal health care services, specifically, antenatal care services from skilled health providers have been given utmost priority in low- and middle-income countries over years with a view of mitigating complications during pregnancy as well as safeguarding the health and survival of both mother and newborn. However, there is a general tendency of pregnant mothers in Bangladesh of receiving skilled antenatal care (SANC) service once, or even never which refrains us to ensure World Health Organization (WHO) recommended eight plus SANC visits, additionally, to meet Sustainable Development Goal (SDG) number three.
Objectives: The study aims at assessing how the average number of SANC visits taken by the reproductive women in Bangladesh changes over the time in rural and urban areas together with finding out the potential demographic and socio-economic factors associated with SANC visits by addressing possible accumulation of zero and one counts in SANC visits.

The research question is as follows: Are estrogen and progesterone receptor genotypes associated with thin endometrium? We performed a prospective cohort study of 129 patients who underwent preimplantation genetic testing for aneuploidies. These patients were categorized according to endometrial thickness: >7 mm control group (n = 94) and ≤7 mm study group (n = 35). Polymorphisms in the genes ESR1 (rs9340799 and rs3138774), ESR2 (rs1256049 and rs4986938), and PGR (rs1042838) were analyzed.
