Article Abstract
Objective: To investigate the relationship of the characteristics of sperm donors with the results of screening and provide some reference for the screening of sperm donors.
Methods: We statistically analyzed the screening data about 12 362 sperm donors at the Guangdong Human Sperm Bank from January 2003 to June 2017 and the relationship of the eligibility rate of screening with the donors' age, education, occupation, marriage, and fatherhood.
Results: Of the 12 362 sperm donors, 3 968 (32.1%) met the standards of semen quality and 3 127 (25.3%) filled all the requirements of sperm donation. The eligibility rate of screening was 27.7% in the donors aged 20－24 years, 24.3% in those aged 25－29 years, 23.8% in those aged 30－34 years, and 17.5% in those aged =≥35 years (P < 0.01); 23.5% in the senior high school students, 24% in the junior college students, 25.9% in the undergraduates, and 30.3% in the postgraduates (P < 0.01); 29.3% in the students versus 22.9% in the others (P < 0.01), 41.5% in the married versus 20.7% in the unmarried (P < 0.01), and 45.6% in the fathers versus 20.9% in the childless husbands (P < 0.01).
Conclusions: A higher eligibility rate of screening was found among the sperm donors aged <35 years or with a bachelor's or higher degree, particularly among students.

Acute lymphoblastic leukemia (ALL) is a malignant condition of lymphoid progenitor cells that primarily affects the pediatric population, but also adults. The 5-year survival rate is 90% in children and approximately 40% in adults, with survival increasing through the use of peripheral stem cell allotransplantation (SCT). The relapse rate after stem cell transplantation (SCT) in adult acute lymphoblastic leukemia (ALL) patients ranges from 35% to 45%, making relapse a major cause of death in this population.

Background: Culture medium enriched with Knockout serum replacement (KSR) can produce in vitro mouse sperm, but it is inefficient, strain-specific and contains bovine products, which limits its use in the human clinic. The study aimed to optimize the culture medium for testicular tissue by using plasma rich in growth factors (PRGF) as a serum supplement, addressing the limitations of KSR.
Methods: Immature testicular tissues from NMRI mice were cultured for 14 days to identify the optimal PRGF concentration using histological analysis and tubular integrity scoring.
Effect of Donor Sperm on Quality of Life in Patients with Severe Oligoasthenosperm After ICSI Failure.

Objective: To explore the effects of donor sperm on reproductive quality of life, sleep quality and erectile function in patients with severe oligoasthenospermia after the failure of intracytoplasmic sperm injection (ICSI), and to provide targeted reference for intervention.
Methods: From January 2021 to December 2023, patients with severe oligoasthenospermia who received assisted pregnancy treatment in Obstetrics and Gynecology Hospital Affiliated to Tongji University were selected as the study objects. Among them, 82 cases using sperm donor assisted pregnancy after ICSI failure were set as the observation group, and 82 cases using propensity score 1:1 matching ICSI failure after ICSI assisted pregnancy were set as the control group.

Research Question: Among women who considered planned oocyte cryopreservation, does decision regret differ between those who pursued planned oocyte cryopreservation and those who did not?
Design: A survey was e-mailed to all women who presented for an initial consultation for planned oocyte cryopreservation between January 2016 and December 2021 using a secure REDCap platform. The survey comprised questions on demographics, reproductive planning and the validated Decision Regret Scale (DRS). Univariable and multivariable models were fitted to compare decision regret in the group who had proceeded with planned oocyte cryopreservation with the group who had not.

Study Question: Does a human fallopian tube (HFT) organoid model offer a favourable apical environment for human sperm survival and motility?
Summary Answer: After differentiation, the apical compartment of a new HFT organoid model provides a favourable environment for sperm motility, which is better than commercial media.
What Is Known Already: HFTs are the site of major events that are crucial for achieving an ongoing pregnancy, such as gamete survival and competence, fertilization steps, and preimplantation embryo development. In order to better understand the tubal physiology and tubal factors involved in these reproductive functions, and to improve still suboptimal in vitro conditions for gamete preparation and embryo culture during IVF, we sought to develop an HFT organoid model from isolated adult stem cells to allow spermatozoa co-culture in the apical compartment.
