“…A sperm-rich fraction from the ampulla and distal vas deferens is deposited next. Finally, the seminal vesicles are emptied [33]. Simultaneous sympathetic stimulation of the bladder neck during ejaculation augments existing closure of the bladder neck and prevents retrograde flow of seminal fluid and sperm into the bladder.…”

Although anejaculation is a relatively uncommon occurrence in the general population, over 12,000 new cases are reported annually. Anejaculation may result from spinal cord injury (SCI), retroperitoneal lymph node dissection (RPLND), diabetes mellitis, transverse myelitis, multiple sclerosis, or psychogenic disorders. At least 30% of men with this problem are or will be married and many will seek help to remedy their infertile state. The evolution of technique and instrumentation over the least 30 years has made electroejaculation an accessible and acceptable form of therapy. Recent successes in inducing ejaculation by means of rectal probe electrostimulation or vibratory stimulation combined with assisted reproductive techniques, such as zygote intrafallopian transfer (ZIFT), gamete intrafallopian transfer (GIFT), and in vitro fertilization (IVF), have provided these men a means of producing their own biologic offspring.

“…The secretions of the prostate glands, seminal vesicles and testicles (corpuscular part of the seminal fluid) are voided into the lumen of the prostate urethra. The seminal fluid is made up for about 15-30% from prostate secretion, for about 50-70% from the fluids of the seminal vesicles and for less than 5% from the product of the testicles, deferential ampules, glands of Cowper and urethral glands (2). The prostate is typically described as a chestnut shape with the base facing the bladder and the apex at the bottom, resting on the external urethral sphincter (3).…”

The objective of this study was to search for an alternative technique to relieve prostatic obstruction due to benign prostatic hyperplasia without affecting the ejaculatory function. The technical requirements are a laser with a wavelength well absorbed by water (good vaporizing effect) and at the same time by hemoglobin (good hemostatic effect) and laser fibers very resistant at high emission power allowing perfect vaporization in a contact mode. The aim of the technique is to avoid damage of the structures that allow the peripheral region of the prostate and the seminal vesicles to discharge their secretions into the posterior urethra. The orifices of the ejaculatory ducts must therefore be identified and preserved, damage of the ejaculatory ducts along their path inside the prostate must be avoided and the so called “genital sphincter” must be saved. The steps of the Leonardi Ejaculation Sparing Technique (LEST) procedure are as follow: Step 1 - ejaculatory duct orifices must be identified and the limits of the vaporization section must be marked. Step 2 - bladder neck is cleaned of the prostate hypertrophic tissue saving, as much as possible, the smooth muscle fibers of the bladder neck. Step 3 - vapo-resection of the lateral lobe (or enucleation of the adenoma) is performed. Step 4 - cautious and meticulous preparation of the prostatic apexes is obtained with saving of the orifices of the ejaculatory ducts. An antegrade ejaculation is maintained in about 80% of cases in patients without a middle lobe, although in the presence of a middle lobe this rate drops to about 50%.

“…The normal range for seminal fructose is 1,200 to 4,500 µg/ml which corresponds to a level of 3.0 mg/cc. 15 It has been found that ejaculates with high sperm counts have lower fructose levels. 16 The seminal vesicles are considered to be the source of seminal fructose and the last portion of a "split" ejaculate should contain the fructose.…”
