Every 24 hours, several million sperms are formed in the
seminal ducts of the testicles. While they are waiting to be ejaculated, they
are stored in the epididymides and when released they are transported through
the seminal ducts to the urethra where they are mixed with fluid from the
prostate. Via contraction of muscle cells found in the spermatic ducts, the
sperm is then ejectulated. The semen consists of secretions from seminal
vesicles, the epididymides and from the prostate as well as sperm.
We perform sperm analyses at our laboratory where we look at sperm concentration, mobility and the amount of sperm.
Abnormal semen samples usually involve reduced mobility or a reduced amount of sperm. This may be due, for example, to the man being exposed to toxic substances, such as solvents, anabolic steroids, drugs or PCBs. Age can also be a factor.
Sometimes there are no sperms in the ejaculate (azoospermia). This may be due, for example, to sterilization, a hormonal disorder, genetic disorder, a blockage in the spermatic ducts or a previous testicular inflammation.
If there are no sperm in the ejaculate, sperm can often
be found in the epididymides or testes by performing a minor intervention
PESA/TESA, see below.
If no sperm are present in the sample, sperm might be found in the epididymis (PESA) or testis (TESA). Om inga spermier finns i provet letar man efter spermier i bitestikeln (PESA) eller testikeln (TESA).The procedure is done by obtainment of sperms in a biposys and the procedure is under local anesthesia. Afterwards you should rest for an hour and and we offer coffee or tea. You can usually can go home after a few hours. We recommend that you don’t work on this day because you will be given pain medication.
