  • semen
  • Another cause of aspermia is ejaculatory duct obstruction, which may result in a complete lack of or a very low-concentration semen (oligospermia), in which the semen contains only the secretion of accessory prostate glands downstream to the orifice of the ejaculatory ducts. (wikipedia.org)
  • This can be the result of absence of puberty, in which the prostate gland and seminal vesicles (which are the main sources of semen) remain small due to lack of androgen exposure and do not produce seminal fluid, or of treatment for prostate cancer, such as maximal androgen blockade. (wikipedia.org)
  • Low-volume, runny/fluid semen (oligospermia) or no semen at all (dry ejaculation/aspermia) are a logical consequence of an obstruction downstream of the seminal vesicles which contribute most to the volume of the semen. (wikipedia.org)
  • monotherapy
  • As such, AR signaling is exceptionally high in the prostate gland, and the effectiveness of bicalutamide monotherapy in the treatment of prostate cancer, which is roughly equivalent to that of gonadotropin-releasing hormone (GnRH) analogues, demonstrates a capacity of bicalutamide to strongly antagonize the AR.

  • help
  • Participants with an illness or disease also participate to help others, but also to possibly receive the newest treatment and to have the additional care and attention from the clinical trial staff. (patientsville.com)
