Can endocrine characteristics of early pregnancy following natural cycle cryopreserved embryo transfer predict live birth?

Research Question: Can serial measurements of serum oestradiol, progesterone and β-human chorionic gonadotrophin (HCG) concentrations, starting from the day of the first positive pregnancy test, predict live birth after natural cycle frozen-thawed embryo transfer (NC-FET)?

Design: This was a historical cohort study of women with a positive pregnancy test following NC-FET, between March 2009 and January 2020. Serum β-HCG, oestradiol and progesterone concentrations were measured on the day of the first pregnancy test and 48 and 96 h later. Pregnancies resulting in a live birth were compared with non-viable pregnancies.

Is there a difference in placental pathology in pregnancies complicated with gestational diabetes A2 versus gestational diabetes A1, versus one abnormal value, on 100 gr glucose tolerance test?

Introduction: The objective of the study was to investigate pregnancy outcome and placental pathology lesions among patients with gestational diabetes mellitus (GDM) versus patients with one abnormal value (OAV), in the oral glucose tolerance test (OGTT).

Methods: A prospective study was performed from 2016 to 2019. All participants performed an OGTT between 24 and 28 weeks.

Pregnancy outcome in women with an intrauterine contraceptive device.

Objective: To investigate pregnancy outcome in patients who conceived with an intrauterine contraceptive device.

Study Design: A retrospective study comparing the pregnancy outcome of women with retained intrauterine device (n = 98), patients after intrauterine device removal in early pregnancy (n = 194), and pregnancies without an intrauterine device (n = 141,191) was performed.

Results: A significant linear association was documented among the 3 groups and adverse outcomes such as preterm delivery (18.
