Abstract

This study explores the effects of calcium channel blockers (CCBs) on sperm function, a critical aspect of male fertility. Male infertility, responsible for 30-50 % of infertility cases, often involves issues with sperm motility and capacitation, both of which are heavily influenced by calcium ions and specific ion channels like CatSper and voltage-dependent calcium channels (VDCCs). CCBs, which are commonly prescribed for cardiovascular conditions, inhibit these calcium channels, potentially disrupting sperm function. A comprehensive literature review showed varied results: some studies demonstrated that CCBs such as nifedipine reduce sperm motility and the acrosome reaction, causing reversible infertility, while others found no significant impact on fertilization rates in IVF treatments. Supporting these findings, animal studies indicated that CCBs impair spermatogenesis and sperm function without necessarily affecting hormonal levels. The research suggests that the impact of CCBs on male fertility might be reversible, emphasizing the need for more extensive in vivo studies to further understand these effects and their clinical significance for patients on CCB therapy.

期刊介绍： Drawing from a large number of disciplines, Reproductive Toxicology publishes timely, original research on the influence of chemical and physical agents on reproduction. Written by and for obstetricians, pediatricians, embryologists, teratologists, geneticists, toxicologists, andrologists, and others interested in detecting potential reproductive hazards, the journal is a forum for communication among researchers and practitioners. Articles focus on the application of in vitro, animal and clinical research to the practice of clinical medicine. All aspects of reproduction are within the scope of Reproductive Toxicology, including the formation and maturation of male and female gametes, sexual function, the events surrounding the fusion of gametes and the development of the fertilized ovum, nourishment and transport of the conceptus within the genital tract, implantation, embryogenesis, intrauterine growth, placentation and placental function, parturition, lactation and neonatal survival. Adverse reproductive effects in males will be considered as significant as adverse effects occurring in females. To provide a balanced presentation of approaches, equal emphasis will be given to clinical and animal or in vitro work. Typical end points that will be studied by contributors include infertility, sexual dysfunction, spontaneous abortion, malformations, abnormal histogenesis, stillbirth, intrauterine growth retardation, prematurity, behavioral abnormalities, and perinatal mortality.
