Revision of hypo-osmotic swelling (HOS) test with a proposition of classified grading system: its comparisons with four different types of human sperm separation technique.

In this study, we arbitrarily classified the morphological changes of sperm under hypo-osmotic condition and compared the results with four different sperm separation techniques. The morphology of classification ranged from a good swelling (SG 3 > SG 2 > SG 1), to non-swelling but reactive (SG 0-R), and completely non-swelling (SG 0). Thirty fresh semen from patients were divided into 4 groups and each processed by washing, swim up, 2-layer column and real time micro-separation system. The prevalent patterns of the swollen sperm in sequence after treatment was SG 0 > SG 1 > SG 3 > SG2 > SG 0-R in fresh semen, and the proportion of SG 0 was almost half of the total % HOS test results. However, SG 3 became the most common swollen form with a significant increase in number with any method of sperm preparation after treatment. The real time technique yielded the highest % rate of SG 3 type of swollen spermatozoa and was the richest in concentration (53+/-3.9%, P < 0.05) as compared with that of swim up (26+/-4.6%), 2-layer (20+/-4.4%), sperm washing (23+/-3.9%), and fresh semen (17+/- 2.8%), respectively. By contrast, 2-layer collected more number of SG0-R (5.3+/-1.2%, P < 0.05) pattern of spermatozoa when compared to real time and swim up. A positive correlation (r = 0.81, P < 0.002) was shown between the % total HOS spermatozoa and total motility of fresh semen but not with morphology. Collectively, an abnormally functional sperm may exist in almost half of a total sperm count from men. It would appear that a better potential fertilization capacity may reside in the more swollen sperm from HOS test than the less swollen sperm and that may be more related with the motility rather than the morphology. The HOS classification and grading system appears valuable in further evaluating sperm quality.

Beliefs about cybersex and Internet-mediated sex of Latino men who have Internet sex with men: relationships with sexual practices in cybersex and in real life.

Cybersex (engaging in sexual self-stimulation while online with another person) and meeting partners for sex are commonly reported among men who have Internet sex with men (MISM). We studied 1,026 Latino MISM in the US and constructed a scale to measure beliefs about cybersex. Respondents were recruited to an online Internet study and compensated for their effort. Factor analysis indicated that there were three dimensions: (1) liking cybersex: perceived anonymity and safety of cybersex; (2) potential for greater IRL interaction in seeking partners on the Internet; and (3) a dimension of negative beliefs about Internet contacts which was not psychometrically stable. Safety referred to physical and HIV-related safety. We formed two scales to describe the first two dimensions. Respondents who were high on the 'liking cybersex: perceived anonymity and safety' scale were more likely than low scorers to use chat-rooms and webcams. They were also more likely than low scorers to have had cybersex and phone sex before meeting. Those who were high on the 'IRL interaction' scale were more likely than low scorers to use e-mail, bulletin boards and paid websites. However, there was significantly less disclosure about HIV status and discussion about safer sex by those higher on the 'IRL interaction scale', and when sex in real life did occur, those higher on the 'IRL interaction' scale were more likely to have receptive oral or anal sex, whereas those high on the 'liking cybersex: perceived anonymity/safety' scale were less likely to have insertive sex or be drunk/high. MISM scoring high on the 'IRL interaction' scale were significantly more likely than low scorers to prefer to meet partners on the Internet. We discuss the implications of the Internet for MSM and for sexual IRL interactions in the Internet age.

Sex counseling of the elderly.

A sympathetic, nonjudgmental approach may reveal sexual dissatisfactions to be the basis of vague complaints about health, opening the way to counseling, changes in drug regimens, and referrals that can greatly improve quality of life.

A case of female autoerotic death.

This paper reviews some of the types of autoerotic death which have been reported and some of the psychodynamic principles which are associated with them. As cases involving females have never been reported, this presentation offers some opportunity to see how psychiatric insight assisted police investigation of an autoerotic death. Crime scene sketching and photographic evidence complement the case material so that the reader can feel he is at the crime scene. A comparison between male and female autoerotic deaths is made.

Rolled up to death. An unusual autoerotic fatality.

Recently, an unusual case of autoerotic death in which a man died of hypoxia after having enclosed himself in plastic was reported in this Journal (1). We present a second case showing many similarities to the one published previously.

Xenolingual autoeroticism.

Reports in the medical literature of autoeroticism seldom describe episodes that are nontraumatic or nonlethal. Reports of bestiality typically involve descriptions of sexual relationships between humans and animals, and are analyzed through psychological methods. No reports of bestiality involving the use of animal tissue for erotic purposes have been published. We report the use of a deer tongue as a masturbatory tool.

A case of autoerotic asphyxia associated with multiplex paraphilia.

During the past 20 years, the sensational aspects of autoerotic fatalities have captured the attention of medical examiners, psychiatrists, law enforcement agents, and the public, as well as the individuals themselves who engage in these dangerous practices. Reports of deaths related to sexual asphyxia have been presented numerous times at national and international meetings and have been the topic of discussion on television talk shows and in the press. Autoerotic fatalities and all the sexual curiosities related to these activities have prompted death scene investigators to publish case reports, and even textbooks, on the subject. The case presented herein is one of a multicomponent paraphilia in which self-asphyxiation (autoasphyxiophilia) led to a fatal autoerotic event.

Autoerotic asphyxiation in a female.

Autoerotic asphyxiation is an unusual but increasingly more frequently occurring phenomenon, with >1000 fatalities in the United States per year. Understanding of this manner of death is likewise increasing, as noted by the growing number of cases reported in the literature. However, this form of accidental death is much less frequently seen in females (male:female ratio >50:1), and there is correspondingly less literature on female victims of autoerotic asphyxiation. The authors present the case of a 31-year-old woman who died of an autoerotic ligature strangulation and review the current literature on the subject. The forensic examiner must be able to discern this syndrome from similar forms of accidental and suicidal death, and from homicidal hanging/strangulation.

Sex offending as a psychosocial sequela of traumatic brain injury.

OBJECTIVE: To describe the nature and extent of sexual offending after traumatic brain injury (TBI). DESIGN: Retrospective file review. SETTING: A brain injury unit providing inpatient and outpatient rehabilitation services. PARTICIPANTS: A review of five years of admissions to the Brain Injury Rehabilitation Unit (N = 477) identified a sample of 29 males who committed 128 incidents of sex offending. MAIN OUTCOME MEASURES: A protocol to record data on demographic, injury, radiological, and psychosocial variables and offending behaviors. RESULTS: Of the total population of 445 clients with TBI, 6.5% (n = 29) were identified as having committed some form of sexual offense. Alcohol was a factor in only three (2.3%) of the incidents, and only two clients had a preinjury history of sexual offending. The most common offenses were the "touching" offenses, followed by exhibitionism and overt sexual aggression. Staff members were the most common targets of the offenses, followed by members of the general public, other people with TBI, and family members. CONCLUSIONS: Sex offending is a significant clinical problem among a small minority of men after TBI. The absence of alcohol and preinjury histories of sexual offending suggest that the brain injury and contingent sequelae were a significant etiological factor underlying the offenses. A number of implications for the clinical management of clients with sexually aberrant behaviors is identified and discussed.
