Fertilisation depends on functioning sperm transport
During ejaculation, sperm moves through the seminal ducts and the urethra to travel through the woman’s vagina into the uterus. In some cases, sufficiently healthy sperm cells may well be present, but they don’t reach the woman’s body because the seminal ducts are blocked. This happens in approximately four percent of all cases of impaired male fertility. The cause of a blocked seminal duct could be prior sterilisation, undeveloped epididymides or adhesions in the epididymides, for example as a result of inflammation. If there is still a fertility problem despite a normal sperm analysis, our doctors will also investigate the possibility of a blocked seminal duct.
