Anatomical or functional defects of the seminal tract may cause flow obstruction of seminal pathways.Retrograde ejaculation can be diagnosed by the presence of sperm in the urine. Also, surgery or trauma along with the medications used for hypertension and benign prostatic hyperplasia can contribute to bladder neck problems. Nerve damage caused by medical conditions such as diabetes or multiple sclerosis can affect the function of bladder neck muscle. Structural or functional damage to the bladder neck muscle causes the backflow of semen during the ejaculation. This can lead to a low volume of semen (hypospermia) or no semen production ( aspermia). This means that the sperm is produced in the testes but on its way out, it gets misdirected into the bladder rather than coming out through the urethra.Some conditions in which ejaculatory reflex dysfunction is observed is multiple sclerosis, diabetic neuropathy, spinal cord injuries, or side effects of certain medications.Įxamples of dysfunction of ejaculatory reflex include:.Ejaculatory reflex dysfunction is one of the leading causes in male infertility. Ejaculatory dysfunction is when a male is unable to ejaculate properly at the time of sexual climax.Causes Įven though there are numerous causes for hypospermia, all of the known contributing factors can be placed into two major distinct categories: Dysfunction of ejaculatory reflex There may not be any symptoms of hypospermia unless it is caused by an abnormality. If hypospermia is caused by retrograde ejaculation, sign include cloudy urine after orgasm. The diagnosis is confirmed when one has a semen volume of less than 2.0 mL on at least two successive spermograms. The most common sign of hypospermia is a low volume of semen during ejaculation. Obstruction of the seminal vesicles results in low semen volumes since they normally produce 70% of the seminal plasma. In addition, low fructose may indicate problems in the prostate, while low semen pH may indicate problems related to the. An acidic seminal pH (pH 8) suggests prostatic involvement. The seminal vesicles, which are major contributors to ejaculate volume, render semen viscous with a pH of 7.2–7.8. The presence of high levels of fructose (a sugar) is normal in the semen and originates almost entirely from the seminal vesicles. ![]() The U.S.-based National Institutes of Health defines hypospermia as a semen volume lower than 2 mL on at least two semen analyses. Of this, around 1% by volume is sperm cells. Normal ejaculate when a man is not drained from prior sex and is suitably aroused is around 1.5–6 mL, although this varies greatly with mood, physical condition, and sexual activity. It should not be confused with oligospermia, which means low sperm count. It is the opposite of hyperspermia, which is a semen volume of more than 5.5 mL. Hypospermia is a condition in which a man has an unusually low ejaculate (or semen) volume, less than 1.5 mL. Teratospermia-fraction of normally formed sperm below lower reference limit Necrospermia-absence of living sperm in the ejaculate Oligospermia-total sperm count below lower reference limit Hypospermia-semen volume below lower reference limit Hyperspermia-semen volume above upper reference limit Asthenozoospermia-sperm motility below lower reference limitĪzoospermia-absence of sperm in the ejaculate
