Abstract Objective: The aims of this study were to study the distribution of the serum VD levels among infertile people and to analyze the relationships between VD levels and the basic conditions of infertile patients, as well as laboratory…

BACKGROUND: With the increasing use of frozen embryo transfer (FET), the best endometrial preparation protocol is continuously being discussed. The hormone replacement therapy (HRT) cycle and letrozole-induced ovulation (L-OI) cycle are ava…

BACKGROUND: The normal physiological function of LH requires a certain concentration range, but because of pituitary desensitization, even on the day of HCG, endogenous levels of LH are low in the follicular-phase long protocol. Therefore, …

BACKGROUND: In some in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) cycles, we may consider transferring one poor-quality embryo with one good-quality embryo. Previous studies have indicated that the poor-quality emb…
