![]() ![]() Sperm motility in a male can be affected by heat, diet, infections, smoking and prolonged sexual activity. The sperms motility can tell how successful the sperm may be at invading the cervical mucus and reaching the egg. At least 50 percent of sperm should be motile and moving forward, and there are usually 15 million motile sperm in a single sample. Sperm is evaluated on both how fast it moves and if it travels in a straight line. Sperm motility is a sperm’s capacity for swimming forward and penetrating the egg. Stress (emotional, psychological, and physical) (Normal range is between 20 million and 120 million per milliliter of semen.) Low sperm count can be caused by a multitude of factors or not explained at all. ![]() Low sperm count is diagnosed when the number of sperm falls below 20 million in a milliliter of semen. Sperm concentration or sperm count – This is the total number of sperm found in a single ejaculate. However, semen with a yellowish-green tent may indicate a prostate infection and you should see your primary care doctor for evaluation. A change in the color of semen is usually temporary and not a health concern. Normal semen is a white, cloudy fluid and quite thick. Semen color– can be affected by age, diet and frequency of ejaculation. A small number of leukocytes can be normal, and are seen even in the absence of infection. Leukocytes – Semen with a high concentration of these are white blood cells, more than 1 million leukocytes per millilitre, can be a sign of inflammation or infection. Causes and symptoms associated with semen viscosity include: If the consistency is too thick, the semen has a harder time leaving the reproductive track. Low or moderate viscosity is considered normal and flows easily. Viscosity– This term refers to the consistency or thickness of the seminal fluid. Mental Stress– if a sample is given when the patient is under unusual stress, semen volume may be low and the study may need to be repeated. Hormonal abnormalities– testing may be needed to check for low levels of serum testosterone. This condition can be a side-effect of bladder neck surgery, diabetes mellitus or alpha-adrenergic drugs.īlockages in a seminal vesicle or ejaculatory duct, sometimes due to a varicocele (varicose vein), or cyst. Retrograde ejaculation– through a urine test doctors can tell if part or all of the semen flows backwards into the bladder. When a low semen volume is found, male infertility patients are evaluated for: In cases of low semen volume, there is not enough fluid to transport sperm into the female reproductive tract, causing fertility problems. Semen volume – Normal semen volume is described as roughly 1 to 5 milliliters (mL) per ejaculation. ![]()
