The Effect of Uterine Contractions on Fertility Outcomes in Frozen Embryo Transfer Cycles: A Cohort Study.

Background: The relationship between uterine peristalsis before embryo transfer and the success of assisted reproductive techniques (ARTs) has not been properly investigated. In this study, the effect of uterine contractions on embryo implantation in frozen embryo transfer (FET) cycles was investigated to determine whether the frequency of uterine contractions can be used as a quantitative marker to assess endometrial receptivity.

Methods: In this cohort study of 68 eligible FET candidates, one hour before embryo transfer (ET), frequency of uterine contractions was assessed with transvaginal ultrasonography.

Risk factors of osteoporosis and osteopenia in postmenopausal women based on the L2-L4 BMD T score of the lumbar spine: a study in Iran.

Objective: To determine the risk factors of osteoporosis and osteopenia of the spine in postmenopausal women.

Method: An analytical cross-sectional study was performed on postmenopausal women. The T-score of the lumbar spine (L2-L4) was measured by densitometry and compared between osteoporotic, osteopenia, and normal women.

Investigation of the relationship between umbilical cord pH and intraventricular hemorrhage of infants delivered preterm.

Objective: We measured the level of pH gases in premature infants at birth, and examined the relationship between brain ultrasonography on the third and seventh day after birth. A case-control study conducted at the Neonatal Intensive Care Unit (NICU) of Shahid Akbar Abadi Hospital, Iran, during the years 2016-2017.

Methods: All premature infants who were admitted to NICU were enrolled in the current study.

Uterus Dysplasia Associated with Cervico-Vaginal Agenesis.

Müllerian ducts can form upper parts of normal female reproductive system and any failure in ductal fusion may result in to müllerian duct anomalies (MDA). We present a case of MDA and a uterus dysplasia with no evidence of cervical or upper vaginal tissue. This case showes the role of magnetic resonace imaging (MRI) on MDA diagnosis and urges the need for a unified reliable and practical classification more compatible with clinical practice.
