Why is sperm white?

The seminal vesicles produce a viscous, fructose-rich fluid forming around 65-70% of the semen base. The white color of the semen is due to secretion from the prostate glands containing enzymes, citric acid, lipids, and acid phosphatase.

Semen is a greyish white bodily fluid that is secreted by the gonads of male animals. It carries sperm or the spermatozoa and fructose and other enzymes that help the sperm to survive to facilitate successful fertilization. The whitish opalescence is due to the large amount of protein that it contains and its slightly turbid appearance is due to the spermatozoa contained within it.

Process of ejaculation

Semen is released during the process of ejaculation and is processed in the seminal vesicle in the pelvis, which is where it is produced.

How does ejaculation occur?

Ejaculation is controlled by the central nervous system and occurs when there is friction on the genitalia and other forms of sexual stimulation. The stimuli lead to impulses that are sent up the spinal cord and into the brain.

Two phases of ejaculation

Ejaculation has two phases:

Phase 1: emission in which the vas deferens (the tubes that store and transport sperm from the testes) contract to squeeze the sperm toward the base of the penis through the prostate gland and into the urethra. The seminal vesicles release their part of the semen that combine with the sperm. The ejaculation is unstoppable at this stage. Phase 2: ejaculation in which the muscles at the base of the penis and urethra contract. This leads to forcing the semen out of the penis (ejaculation and orgasm) and this phase also has a bladder neck contraction. The bladder neck contracts to prevent the back flow of the semen into the urinary tract. Dry orgasm can occur even without delivery of semen (ejaculation) from the penis. Erection declines normally following ejaculation.

Semen composition

The semen travels through the ejaculatory ducts and mixes with fluids from the seminal vesicles, the prostrate, and the bulbourethral glands. The seminal vesicles produce a viscous, fructose-rich fluid forming around 65-70% of the semen base. The white color of the semen is due to secretion from the prostate glands containing enzymes, citric acid, lipids, and acid phosphatase. This forms around 25-30% of the semen base. At each ejaculation around 200-500 million sperms are released by the testes. This forms about 2-5% of the semen composition. Apart from these, the bulbourethral glands produce a clear secretion. This helps in mobility of the sperm cells in the vagina and cervix. The glands’ secretion contribute less than 1% to the overall semen composition.

The semen comprises of:

fructose

ascorbic acid

zinc

cholesterol

protein

calcium

chlorine

blood group antigens

citric acid

DNA

Magnesium

vitamin B12

phosphorus

sodium

potassium

uric acid

lactic acid

nitrogen

other nutrients

Semen per ejaculation

Ejaculation is a complex process and the compositions of the final semen come together in the posterior urethra and only become mixed after ejaculation is complete. The volume of semen released per ejaculate varies. Approximately an average around 3.4 milliliters is ejaculated at one time. It can be as high as 4.99 milliliters or as low as 2.3 milliliters. If there is a prolonged gap between ejaculations, the number of sperm in the semen increases but there is no overall increase in the semen.

How much saw palmetto should I take for prostate?

Dosage. Clinical studies have used a dosage of 160 mg twice daily or 320 mg once daily of a lipophilic extract containing 80 to 90 percent of the volatile oil. A daily dosage of 480 mg was not found to be any more effective in a six-month study of dosages.

Treatments for BPH can be evaluated by their effect on symptoms such as diminished urine stream, post-void dribbling, overflow incontinence, and urinary retention, or by less useful measures such as urine flow rate, changes in prostate size, and residual volume. In a Cochrane Review, investigators conducted a meta-analysis of randomized controlled studies comparing saw palmetto with placebo or other drugs.6 [Evidence level A: systematic e r view of randomized controlled trials RCTs] The review combined the results of 21 trials with durations of four to 48 weeks. The 21 studies included a total of 3,139 men with a mean age of 65 years (range: 40 to 88 years). According to the International Prostate Symptom Scale, these men had moderate symptoms, with an average urologic score of 14.4 points out of a possible 35 (moderate BPH symptoms range from eight to 19).6 In the 13 studies that reported symptom scores, saw palmetto improved symptom scores, individual symptoms, and flow measures more than placebo. Patients and physicians were more likely to report improvement in symptoms with saw palmetto treatment than with placebo. In the12 studies that reported nocturia results, saw palmetto reduced nocturia by 25 percent compared with placebo.
