Prazosin is also useful in treating urinary hesitancy associated with benign prostatic hyperplasia, blocking α 1-adrenergic receptors, which control constriction of both the prostate and urethra. Although not a first-line choice for either hypertension or benign prostatic hyperplasia, it is a choice for people who present with both problems ...
Female ejaculate may result from sexual activity for some women, especially during orgasm. [3] [4] In addition to PSA and acid phosphatase, Skene's gland fluid contains high concentrations of glucose and fructose. [3] In an amount of a few milliliters, fluid is secreted from these glands when stimulated from inside the vagina.
Non-neurogenic chronic urinary retention does not have a standardized definition; however, urine volumes >300mL can be used as an informal indicator. [7] Diagnosis of urinary retention is conducted over a period of 6 months, with 2 separate measurements of urine volume 6 months apart.
This is a table of volume of distribution (V d) for various medication. For comparison, those with a V d L/kg body weight of less than 0.2 are mainly distributed in blood plasma, 0.2-0.7 mostly in the extracellular fluid and those with more than 0.7 are distributed throughout total body water.
The prostatic fluid is expelled in the first part of ejaculate, together with most of the sperm, because of the action of smooth muscle tissue within the prostate. In comparison with the few spermatozoa expelled together with mainly seminal vesicular fluid, those in prostatic fluid have better motility , longer survival, and better protection ...
Patients who need alpha blockers for BPH, but have a history of hypotension or postural heart failure, should use these drugs with caution, as it may result in an even greater decrease in blood pressure or make heart failure even worse. [35] [36] The most compelling contraindication is urinary incontinence and overall fluid retention.
Q max is used as an indicator for the diagnosis of enlarged prostate. A lower Q max may indicate that the enlarged prostate puts pressure on the urethra, partially occluding it. Uroflowmetry is performed by urinating into a special urinal, toilet, or disposable device that has a measuring device built in. [1] The average rate changes with age. [1]
[9] [10] It can also reduce DHT levels in the prostate by 97 to 99% in men with prostate cancer. [11] [12] Epristeride (brand names Aipuliete, Chuanliu) is marketed in China for the treatment of benign prostatic hyperplasia. [13] [14] [15] However, it can only decrease circulating DHT levels by about 25 to 54%. [16]
