Abstract Study question Can different observers successfully identify adenomyosis, based on the revised MUSA (Morphological Uterus Sonographic Assessment) criteria, using archived ultrasound pictures? Summary answer Stored ultrasound pictur…

Abstract Objective: To apply a combined protocol using GnRH agonists and letrozole for endometrial preparation in patients with severe adenomyosis undergoing frozen euploid single embryo transfer (eFET). Design: Case series. Setting: Terti…

PurposeThe objective of this study was to investigate whether women with diminished ovarian reserve who planned for PGT-A exhibit a lower number of blastocysts for biopsy, ploidy outcomes, and blastocyst quality on day 5, regardless of age.…

ContextThe widespread distribution of the Vitamin D (VitD) receptor in reproductive tissues suggests an important role for VitD in human reproduction. The assessment of patient´s VitD is based on the 25-hydroxyvitamin D (25(OH)D) metabolite…

Objective: To evaluate intraday serum progesterone levels on the day of final oocyte maturation in women undergoing ovarian stimulation in a GnRH-antagonist protocol. Study design, size, and duration: The study was done as a prospective obs…

BackgroundIn the recent years, vitamin D has become a topical subject and a focus of research not only in reproductive medicine but across many medical disciplines. In reproductive medicine, studies have identified an association between vi…

Previous publications suggest a reduction in the ovarian reserve following ovarian surgery. The influence of the underlying disease, histology, size of the ovarian cyst and type of procedure remains unclear. The aim of this study was to inv…
