Within Subject Variation Of Seminal Parameters After 5 Days Of Abstinence

World over, male infertility is on rise. Several causes for infertility are known. Semen examination report is an important document, of which total sperm count and percentage of sperm motility are

Effect of sexual arousal on semen parameters during abstinence

It was observed that all parameters did not change except semen volume and total motile sperm count, and to understand the effect of sexual arousal during the sexual abstinence, the authors need studies with high patient number and longer follow‐up.

The use of sexual activity measurements to assess ejaculatory performance of boars

The highest correlation between ejaculate volume and sexual urge levels was observed in the youngest boars at the beginning of insemination service, suggesting that changes in ejaculatory efficiency are the most dynamic at the age of approx.

Duration of sexual abstinence: epididymal and accessory sex gland secretions and their relationship to sperm motility.

Within the time interval recommended by the WHO (2-7 days), the length of the abstinence period is associated with sperm characteristics and should be taken into consideration when interpreting results of semen analysis.

The Effect of Ejaculatory Abstinence Interval on Sperm Parameters and Clinical Outcome of ART. A Systematic Review of the Literature

The results from the included studies indicate that WHO abstinence recommendations may need revision, given that a shorter ejaculatory abstinence interval appears to be associated with improved sperm parameters, such as sperm DNA fragmentation, progressive motility or morphology, while evidence suggests a potential increase in embryo euploidy rates and pregnancy outcomes.

Considerations in evaluating human spermatogenesis on the basis of total sperm per ejaculate.

Clinicians wishing to maximize number of fully functional sperm available during intercourse, or for artificial insemination, might wish to recommend 6-7 days of abstinence, and why and when TSperm/h might provide a meaningful quantitative evaluation of spermatogenesis is examined.

Effect of Abstinence Time on Semen Parameters among Male Patients Referring to Urology Clinic

Results of the present study showed that the abstinence time is significantly associated with the total sperm count, sperm concentration seminal fluid volume and pH.

The impact of regular sperm donation on bulls’ seminal plasma hormonal profile and phantom response

Higher levels of testosterone and lower levels of estradiol and prostaglandins resulted in higher sexual performance, expressed by a stronger response to the phantom, and regular use has a positive effect on the secretion of sex hormones in bulls.

ASSESSMENT OF THE RELATIONSHIP BETWEEN PHYSICAL EJACULATE PARAMETERS AND THE SEXUAL ACTIVITY OF LANDRACE BOARS

Ejaculate parameters were shown to depend on the sexual activity of boars, as identified after 3, 6 and 9 months of insemination service, and it was determined that the degree of this interrelation increases along with age and development.

Sexual arousal and the quality of semen produced by masturbation.

It is concluded that sexual arousal has no significant influence on the quality of an ejaculate produced by masturbation and the use of visual erotic stimulation is recommended when patients and donors have to produce a semen sample in the university surroundings of a fertility clinic.

Endocrinological, biophysical, and biochemical parameters of semen collected via masturbation versus sexual intercourse.

Semen collection during intercourse using an SCD appears to be the method of choice for selecting semen samples for artificial insemination and the differences in prostatic secretory function and semen parameters may not be attributed to differences in hormonal levels.

Effect of abstinence on sperm motility in normal men.

Influence of abstinence length on ejaculate characteristics.

While a shorter abstinence is associated with a smaller semen volume the length of abstinence does not affect sperm concentration, and the place of collection did not affect semen characteristics.

Influence of sexual stimulation on sperm parameters in semen samples collected via masturbation from normozoospermic men or cryptozoospermic men participating in an assisted reproduction programme

The appearance of spermatozoa after masturbation with VIM in the vast majority of cryptozoospermic men is of clinical significance in programmes applying intracytoplasmic sperm injections for the management of severe male infertility and obviates the need for testicular biopsy.

Premature ejaculation: investigation of factors in ejaculatory latency.

Factors hypothesized as being related to ejaculatory latency were evaluated to determine whether they may be implicated in premature ejaculation. Data from 10 premature ejaculators and 14 normal male

Variation of semen quality in normal men.

Although changes in semen-analysis results occurred over the year, no consistent trend was seen and no evidence was found to suggest that the differences were due to modifications of the methods employed by the laboratory, or to the change of season.
