Background:The research and advances in obstetrics are performed to overcome abnormal vaginal deliveries. The obstetrician's skill using digital vaginal examination (DVE) remains a personal skill with limitations. Objective: Assessment of the ability of intrapartum ultrasound capability to observe the progression of normal labor in the first stage compared to DVE accurately and objectively. Patients and methods: This prospective cohort study, was conducted on 62 singleton pregnancies in their 38-40 weeks of pregnancy at Obstetrics and Gynecology ultrasound unit and Maternity Hospital, during a period between 2018 to 2020. All cases received clinical examination including, general, abdominal, and obstetrical examination and ultrasonography examination including, transvaginal, transabdominal, and transperineal. Result: The transvaginal ultrasound evaluated the rate of cervical dilatation at the first stage of labor and the length of the cervix showed a statistically significant negative correlation and statistically significant positive correlation between time of labor progress at first and cervical length. There was statistically significantly higher mean cervical dilatation by DVE than US findings (4. 58 & 4.29, respectively). Conclusion: Ultrasound usage possesses a potential role in predicting vaginal delivery success and helping the promotion of safe operative delivery.

Background: Improvements in IVF have led to an increased number of embryos not available for immediate transfer due to concern about multiple pregnancies. Cryopreservation of supernumerary embryos with subsequent frozen-thawed embryo transfer (FET) is an excellent solution to surplus embryos and has become a common practice in infertility centers.Objectives: The aim of the current work was to evaluate the success rate of hormonal replacement therapy (HRT) and modified natural cycle protocol in frozen-thawed embryo transfer (FET). Patients and methods: Randomized controlled trial study was done at department of Obstetrics and Gynecology, Zagazig University and in a private Center in the period from January 2021 to March 2022. Included 84 women who underwent Frozen-thawed embryo transfer (FET). The women were divided into 2 groups; Natural cycle group included 42 women, 3 of them escaped from the study. Artificial cycle group included 42 women, 2 of them escaped from the study. Result: This study showed that there were no statistically significant differences in the number of embryo thawing, the number of embryo transfers, the degree of embryos, as well as the rate of biochemical and clinical and continuous pregnancy among the studied groups. Conclusion: It could be concluded that both modified natural and artificial cycle for endometrial preparation in frozenthawed embryo transfer cycles appears to be equally successful about pregnancy rates.
