Infertility, Male Clinical Trial
Official title:
The Influence of Lead and Cadmium Seminal Plasma Level on Intracytoplasmic Sperm Injection (ICSI) Outcome
To evaluate the influence of lead (pb) and cadmium (cd) seminal plasma level on embryo development and pregnancy rate during intracytoplasmic sperm injection (ICSI).
The inability to have children, both by natural procreation and medically assisted reproduction, is not only a challenge for medical science but also an economic and social problem. Infertility is a complex disorder with multiple genetic and environmental causes (Gill et al.,2018) One of the factors that may be responsible for this phenomenon is contamination of the environment with heavy metals Two of the most widely-recognized reproductive toxins are lead (Pb) and cadmium (Cd) (Wdowiak et al., 2018). Food, water and tobacco and smoking are the primary source of baseline exposure to lead and cadmium (Tong et al., 2000; Bernard, 2008) Each of cadmium and lead were inversely correlated with semen parameters as, ejaculate volume, sperm count, sperm concentration, live sperms and rapid mobility. ( Zaki et al.,2018). Reproductive contaminants found in follicular fluid (FF) and seminal plasma may compromise the quality of oocytes and or sperm, which may become one of the risk factors for reproductive outcome. The data available suggests certain chemicals or their metabolite reaches the seminal plasma and/or FF, indicating their possible impact in In Vitro fertilization (IVF) outcome ,However, more studies are needed with regard to relationship between exposure level and affected parameters. (Kumar et al., 2010). ;
