Sertoli cell-only syndrome (Germ cell aplasia)


The condition is characterized by the incapability to produce sperm, performing in azoospermic semen. The cause of origin- cell aplasia isn't known; still, some experimenters believe the condition develops from hormonal remedy, irradiation, gonadotropin scarcities, environmental poisons, and other factors. Fertility is insolvable for utmost cases with origin- cell aplasia and patron sperm is generally recommended to help couples conceive.

Other tests that may be helpful in diagnosing infertility include:

  • Blood work to check hormone situations of follicle stimulating hormone (FSH) and testosterone, also luteinizing hormone (LH), estradiol, or prolactin
  • Tests to check for the presence of infection including HIV, hepatitis, Gonorrhea and Chlamydia all of which can vitiate fertility.
  • Specialized semen analysis, including inheritable testing of the sperm and evaluation for the presence antisperm antibodies
  • Post-ejaculatory urine sample to rule out or indicate retrograde interjection.
  • Cervical mucus penetration test apost-coital test is designed to estimate the effect of a woman’s cervical mucus on a man’s sperm.
  • Inheritable testing may be recommended to couples with oppressively low sperm counts who'll be using intracytoplasmic sperm injection (ICSI). Inheritable testing can help identify the possibility of heritable inheritable conditions that can be passed on to children.


The primary sign of Sertoli cell-only pattern (SCO pattern) is a lack of product of sperm cells (azoospermia). Men are generally diagnosed with this condition when they're between 20 and 40 times of age and are being estimated for gravidity. Some cases with SCO pattern may have small testicles.

 In some cases, SCO pattern can be caused by another underpinning complaint. In these cases, it's possible for affected men to have other symptoms. For illustration, some men with SCO pattern are latterly diagnosed with Klinefelter pattern, another cause of manly gravidity. The signs and symptoms associated with underpinning causes of SCO pattern can vary.

This table lists symptoms that people with this complaint may have. For utmost conditions, symptoms will vary from person to person. People with the same complaint may not have all the symptoms listed. This information comes from a database called the Mortal Phenotype Ontology (HPO). The HPO collects information on symptoms that have been described in medical coffers. The HPO is streamlined regularly. Use the HPO ID to pierce more in- depth information about a symptom.


Sertoli cell-only pattern (SCO pattern) can be caused by a variety of factors, but utmost cases do for unknown reasons (idiopathic). Implicit causes of SCO pattern include:

  • Inheritable factors the infertility is caused by specific inheritable changes
  • Hormonal factors the dropped sperm product is caused by hormonal problems
  • Poison exposure an exposure to a chemical caused dropped sperm cell product
  • History of radiation radiation to the testicular region caused dropped sperm cell product
  • History of trauma trauma to the testicular region caused dropped sperm cell product
  • History of a viral infection affecting the testicles


In some cases, Sertoli cell-only pattern (SCO pattern) may be caused by a inheritable change (mutation). One possible illustration of inheritable causes of Sertoli cell-only pattern include elisions of inheritable information on regions of the Y-chromosome, especially on the azoospermia factor (AZF) region of the Y-chromosome.

Still, it's doubtful that this change was inherited, If SCO pattern is caused by a inheritable change in a particular existent. This is because utmost inheritable causes of SCO pattern are caused by mutations of the Y chromosome. A joker’s Y chromosome is inherited from his father, and men who have SCO pattern are generally not suitable to have children unless they use specific reproductive technologies. Thus, it would be doubtful for a person to have inherited the cause of SCO pattern from his father. In some cases, however, a inheritable change causing SCO pattern may do on another chromosome. In these cases, it's possible for SCO pattern to run in families. Further information about reproductive technologies that may allow a man with SCO pattern to have children is included below.


Sertoli cell-only pattern (SCO pattern) is generally suspected in men who present with gravidity despite having normal testosterone situations. Tests to confirm the opinion include a determination of azoospermia (no sperm product) and increased FSH (follicle- stimulating hormone) situations. The opinion is generally verified by a vivisection of the testicles showing no sperm product.


There's presently no available treatment for Sertoli cell-only pattern (SCO pattern). In some cases, men with SCO pattern have veritably low situations of sperm product. In these situations, a procedure called testicular sperm birth (TESE) can take place in order to remove sperm from the man’s testicles. The sperm can also be fitted directly into a woman’s egg in a procedure called intracytoplasmic sperm injection (ICSI).

Unfortunately, success rate for this procedure may be limited. Current reports suggest that about 13 of men with SCO pattern had successful procedures that redounded in having a child. Success of the procedure depends on the presence of any sperm cells in the testes, and numerous men with SCO pattern may have complete absence of sperm cells. The success of the procedure may be better at centers that specialize in treating men with gravidity, including men with SCO pattern. In cases where TESE-ICSI is used, inheritable testing is recommended beforehand for further information about whether or not the pattern could be passed on to his children.


Men with Sertoli cell-only pattern (SCO pattern) who wish to have children have a number of options. Other than the reproductive technology options mentioned over, men with SCO pattern can choose to pursue relinquishment or their mates can choose to have their eggs inculcated with a patron sperm.

Men with SCO pattern have been reported to have about a10.5 threat to develop testicular cancer in their continuances. It's important to bandy this threat with your croaker and bandy styles of looking for testicular cancer similar as clinical evaluations, ultrasonography, or MRI.
