Objective: To investigate the relationship between the maternal serum inhibin A concentrations and the number of fetuses. Further, the maternal serum inhibin A levels for twin pregnancies and multiple pregnancies reduced to twins in the second trimester were compared.
Methods: Three groups of women with pregnancies following in vitro fertilization and embryo transfer were recruited for this study. Groups 1, 2 and 3 included 20 singleton pregnancies, 37 twin pregnancies, and 35 multifetal pregnancies, respectively. In group 3, multifetal reduction was performed during 10-12 weeks of gestation. Blood samples were obtained longitudinally at 10th, 12th, 15th and 18th week of gestation.
Results: There was a significant association between the number of fetuses and maternal plasma inhibin A prior to multifetal reduction. The inhibin A levels were not significantly different between twin and multifetal reduced twin pregnancies at 15th and 18th weeks of gestation.
Conclusion: In multifetal reduction to twin pregnancies, the maternal serum levels of inhibin A decrease to the level of twin pregnancies during the second trimester. Therefore, inhibin A may be effectively used as a marker for Down syndrome screening in cases of twin pregnancy following multifetal reduction.

Background: The effectiveness of changing the type of luteal phase support in patients with poor ovarian response (POR) remains unclear based on the available evidence. This study aimed to compare the effectiveness of various luteal phase support (LPS) methods, including progesterone alone, human chorionic gonadotropin (hCG) alone, and the combination of progesterone with hCG, in these patients.
Materials And Methods: In this randomized clinical trial, 375 patients diagnosed with POR based on the Bologna criteria underwent intracytoplasmic sperm injection-embryo transfer (ET) cycles at the Royan Institute between November 2015 and June 2019.

Objective: Monochorionic diamniotic (MCDA) twins with amniotic fluid abnormalities that do not meet criteria for twin-twin transfusion syndrome (TTTS) concern physicians and families. This study aimed to describe the natural history of amniotic fluid abnormalities.
Methods: In this retrospective case-control study, TTTS screening ultrasounds and clinical records throughout all MCDA twin gestations were reviewed between 2018 and 2022 at a tertiary fetal care center.
Birth weight and ponderal index percentiles for twins based on sex and chorionicity in a center of Guangdong Province, China.

Background: Intrauterine growth restriction (IUGR) which is judged based on birth weight and gestational age, is associated with increased neonatal mobility and mortality and also has a further impact on physical and mental health during later in life. Using the birth weight percentile for singletons to assess twins might not accurately reflect the growth status of the twins; this could potentially lead to an incorrect evaluation of growth-restricted children. For a more precise assessment of twin newborns, it is beneficial to utilize twin-specific birth weight percentile curves and ponderal index (PI) curves that consider factors such as birth order and sex.

The twin reversed arterial perfusion (TRAP) sequence is a rare complication associated with monochorionic twins. It is characterized by blood flow from the umbilical artery of the normal (pump) twin to the umbilical artery of the abnormal (acardiac) twin via artery-to-artery anastomosis. This condition is associated with 100% mortality in the acardiac twin and a high rate of perinatal morbidity and mortality in the pump twin, primarily due to intrauterine hypoxic injury, heart failure, and prematurity.
