The addition of dydrogesterone improves the outcomes of pregnant women with low progesterone levels when receiving vaginal progesterone alone as luteal support in HRT-FET cycles

Reproductive medicine and biology ·doi:10.1002/rmb2.12511

PURPOSE: Vaginal progesterone (VP) alone has been used as luteal support (LS) in HRT-FET cycles without measuring serum progesterone concentrations (SPC) because it can achieve adequate intrauterine progesterone levels. However, several rep…

A novel orally active gonadotropin-releasing hormone antagonist, relugolix, is a potential substitute for injectable GnRH antagonists in controlled ovarian stimulation in assisted reproductive technology

Reproductive medicine and biology ·doi:10.1002/rmb2.12424

PURPOSE: To evaluate the efficacy of an oral gonadotropin-releasing hormone antagonist (GnRH Ant), relugolix (R), for assisted reproductive technology (ART). METHODS: We enrolled women undergoing ART using a GnRH Ant for controlled ovarian…

Different anti-Műllerian hormone (AMH) levels respond to distinct ovarian stimulation methods in assisted reproductive technology (ART): Clues to better ART outcomes

Reproductive medicine and biology ·doi:10.1002/rmb2.12270

PURPOSE: We asked whether the relationship between anti-Műllerian hormone (AMH) value and the response to ovarian stimulation (OS) might be AMH value-related and differ for each regimen, aiming at getting clues as to how to choose OS protoc…

Identifying a possible factor for the increased newborn size in singleton pregnancies after assisted reproductive technology using cryopreserved embryos, in comparison with fresh embryos

Reproductive medicine and biology ·doi:10.1002/rmb2.12206

PURPOSE: To determine whether the cycle regimens that are used for endometrial preparation are associated with the birthweight (BW) after assisted reproductive technology (ART) using frozen-thawed embryo transfer (FET). METHODS: The BW of …
