High ejaculate volume: a distinct entity?

Abstract

In this study clinical, andrological and endocrinological data of a group of 101 patients with ejaculate volume of at least 8.0 ml are compared with data of 100 consecutive patients attending our infertility clinic. Within both groups correlations between different parameters are observed. Between both groups a significant difference in total sperm output is noted suggesting a 'dilution oligozoospermia' in the high ejaculate volume group. We suggest that, in order to avoid a falsely unfavourable fertility prognosis for those patients, total sperm output should be considered rather than sperm density. From the point of view of nomenclature, the term 'relative oligozoospermia' seems justified in cases with very high ejaculate volumes.

Penetration and ejaculation; forensic aspects of rape.

A study was made of 104 alleged rape cases submitted to the DSIR in Auckland by the police over a period of approximately two years. Data were collected relating to the victims' perceptions of penetration and ejaculation, and the forensic evidence for these events. Seminal fluid was detected in 69 (66%) of the cases. In 81 (78%) of the cases penetration was reported; seminal fluid was detected in 58 of these. Of the five (5%) cases where it was reported that penetration did not occur, seminal fluid was detected in two. Forty (38%) of the victims reported ejaculation and seminal fluid was detected by 34 of these. Ejaculation was reported not to have occurred in 16 (15%) of the cases; seminal fluid was detected in seven of these. The victims of alleged sexual assault may not remember accurately if penetration or ejaculation took place.

The effect of semen quality of the electrical current and heat generated during rectal probe electroejaculation.

Rectal probe electroejaculation is effective in procuring sperm from spinal cord injured patients with ejaculatory incompetence. The seminal quality in these patients is usually suboptimal and the motility is almost always low. We conducted an in vitro experiment to determine whether the heat and current generated during rectal probe electroejaculation impaired sperm motility or forward progression, or if the poor semen quality is the result of existing testicular dysfunction.

An unusual case of retrograde ejaculation.

Despite normal seminal analyses obtained for assay by masturbation, persistent negative postcoital tests led to the testing of postejaculatory urine following normal intercourse. This disclosed an unusual problem of retrograde ejaculation occurring only during intercourse. The mechanism for this selective form of retrograde ejaculation is unknown.
