Retrograde ejaculation is a common side effect of medications, such as tamsulosin, [6] that are used to relax the muscles of the urinary tract, treating conditions such as benign prostatic hyperplasia. By relaxing the bladder sphincter muscle, the likelihood of retrograde ejaculation is increased.
Tamsulosin can also cause retrograde ejaculation, which occurs when semen is redirected to the urinary bladder instead of being ejaculated normally. This is because tamsulosin relaxes the muscles of the urethral sphincters , which are normally closed during ejaculation.
Alpha-1 blockers can be used, but it can result in side effects such as increased urination and retrograde ejaculation. Phenoxybenzamine , a non-competitive α 1 and α 2 blocker was used by Dr. Giles Brindley in the first intracavernosal pharmacotherapy for erectile dysfunction.
This is also the case for Tamsulosin and it may be assumed that the others alpha-1 blockers work in a similar manner, since Tamsulosin is an alpha-1-a blocker and Prazosin is an alpha-1 blocker. [30] The risk for floppy iris syndrome during cataract surgery is elevated when the patient is using an alpha-1 blocker.
Hypospermia is a condition in which a man has an unusually low ejaculate (or semen) volume, less than 1.5 mL. It is the opposite of hyperspermia, which is a semen volume of more than 5.5 mL. [1] It should not be confused with oligospermia, which means low sperm count. Normal ejaculate when a man is not drained from prior sex and is suitably ...
Physical Causes of PE. Certain physical and biological factors may cause or contribute to PE. These include: Abnormal hormone levels. Certain hormones, such as prolactin, luteinizing hormone (LH ...
The evidence supporting a viral cause of prostatitis and chronic pelvic pain syndrome is weak. Single case reports have implicated herpes simplex virus (HSV) and cytomegalovirus (CMV), but a study using PCR failed to demonstrate the presence of viral DNA in patients with chronic pelvic pain syndrome undergoing radical prostatectomy for ...
One of the causes of aspermia is retrograde ejaculation, because of that the sperm is kept into the bladder and the final ejaculate is 0 mL. [1] It can be brought on by excessive drug use, or as a result of prostate surgery. It can also be caused by alpha blockers such as tamsulosin and silodosin.
