Introduction: Male infertility, defined as the inability to impregnate a fertile female, arises from various factors, among which sperm motility plays a pivotal role in determining reproductive potential. Seminal plasma, a complex fluid comprising diverse proteins, serves to nourish and support sperm, thereby facilitating their function within the female reproductive tract for successful conception. Normozoospermia denotes normal sperm motility in males, whereas asthenozoospermia indicates reduced sperm motility.

Department of Assisted Reproduction, Shanghai Ninth People's Hospital, Shanghai Jiao Tong University School of Medicine, Shanghai, China.

Background: Techniques for sperm cryopreservation have exhibited their potential in male fertility preservation. The use of frozen-thawed sperm in fertilization (IVF) cycles is widespread today. However, many studies reported that cryopreservation might have adverse effects on sperm DNA integrity, motility, and fertilization, probably due to cold shock, intra- and extracellular ice crystals, and excess reactive oxygen species (ROS).

Sperm Bank & Andrology Unit, Shamir Medical Center, Zerifin, Israel; IVF Department, Shamir Medical Center, Zerifin, Israel; Sackler Medical School, Tel Aviv University, Tel Aviv, Israel.

Objectives: This study investigates sperm utilization and disposal patterns in Oligoasthenoteratozoospermia (OAT) patients undergoing long-term sperm storage. OAT is a major contributor to male infertility. Cryopreservation is a common practice as a "fertility insurance" in case of further deterioration until azoospermia.

Background: Liuweizhiji Gegen-Sangshen oral liquid (LGS), as a Chinese medicinal preparation, is developed from a Traditional Chinese medicinal formula consisting of six Chinese medicinal herbs, including Puerariae lobatae radix, Hoveniae semen, Imperatae rhizoma, Crataegi fructus, Mori fructus and Canarli fructus, and has been extensively utilized in the prevention and treatment of alcoholic liver disease (ALD) clinically. Previous study has demonstrated that LGS dose-dependently mitigated ALD in rat models. However, whether and how the main characteristic constituents of LGS (the flavonoid and polysaccharide fractions, LGSF and LGSP) contribute to the anti-ALD effect remains unclear.
