Intrauterine G-CSF Infusion for Thin Endometrium

Thin endometrium is a condition in which the lining of the uterus is too thin during preparation for embryo transfer. This may reduce the chance of pregnancy and live birth in patients undergoing frozen-thawed embryo transfer. This study will evaluate whether intrauterine infusion of granulocyte colony-stimulating factor, also called G-CSF, can improve pregnancy outcomes in patients with thin endometrium. Participants will be randomly assigned to one of two groups. The experimental group will receive mild endometrial stimulation followed by intrauterine infusion of G-CSF 300 μg. The control group will receive the same mild endometrial stimulation followed by intrauterine infusion of normal saline. Both groups will then continue standard endometrial preparation for frozen-thawed embryo transfer. The main outcome of the study is the live birth rate. The study will also assess endometrial thickness, endometrial blood flow, clinical pregnancy rate, miscarriage rate, and safety outcomes, including adverse events, pregnancy complications, fetal malformations, and neonatal birth defects. Participants will be followed from enrollment through embryo transfer, pregnancy assessment, and delivery. This is a single-center, prospective, randomized controlled trial conducted at Nanjing Drum Tower Hospital, The Affiliated Hospital of Nanjing University Medical School. The planned sample size is 620 participants.

A Randomized Controlled Study on the Effect of MRJPs on Improving Ovarian Function and Endometrial Receptivity

This study will assess the effects of the rose tablet candies produced by MRJPs on the subjects, evaluate the role of MRJPs in the ovarian function and endometrial receptivity of women, reveal the potential application value of MRJPs in reproductive health, and determine its safety and effectiveness.

Application of Platelet-rich Plasma (PRP) in Reproductive Medicine

Female fertility is affected by many factors, such as ovarian function, fallopian tube patency, uterine environment, and mental state, among which the ovaries and endometrium are more important. In reproductive medicine, ovarian dysfunction, poor ovarian reaction, intrauterine adhesion, recurrent implantation failure, and thin endometrium are the five most common diseases that affect fertility. These five diseases lack effective treatment, and previous studies have shown that platelet-rich plasma is promising in treating these five diseases, so it is necessary to further explore the therapeutic effect and potential mechanism.
