Male multiple orgasms: a descriptive study.

Little is known about the phenomenon of multiple orgasms among men. The traditional view assumes there are two stages of orgasm in the healthy male: emission following orgasm almost instantly, followed by a refractory period. Contradictory experiences have been reported by men. Data from interviews with 21 multiply orgasmic men are presented. Men reported that detumescence does not always follow an orgasm, that a nonejaculatory orgasm can occur prior to as well as after an ejaculatory orgasm, and that it is possible to have a series of orgasms. Some of the men reported always having been multiply orgasmic, whereas others experienced it relatively late in life. Others have actively learned to become multiply orgasmic. It may be that our traditional expectations regarding the possible limited range of male orgasmic capacity have profoundly influenced men's behavior as well as research in this area.

Abortions in relation to age, coital frequency, and fecundity.

Abortion rates show variations by age in the United States. This article addresses the question of age variations in abortions. Since the probability of pregnancy is increased in direct proportion to increased coital frequency, age and coitus-specific abortion rates are calculated. Since the probability of pregnancy is related to fecundity, age and fecundity abortion rates are also calculated. When combining coital frequency and fecundity with the age-specific abortion rates, the variation by age disappears for all women except teen-agers.

Contrasting speech patterns in apraxia of speech and phonemic paraphasia.

This study was designed to determine if perceptual phonological analysis would reveal distinctions between patients with apraxia of speech and patients with phonemic paraphasic speech. Test findings from 10 Broca's aphasics with apraxia of speech were compared to findings from 10 paraphasic speakers (5 conduction and 5 Wernicke's aphasics). Several marked differences were revealed. Predominant locus of errors and relative difficulty of different classes of phonemic segments were significant discriminators. There was a nonsignificant trend for substituted phonemes to be further from target phonetically in the paraphasic patients. In addition, the two groups showed certain consistent differences in the types of errors they produced. Apraxic patients produced many errors of transitionalization, while sequencing errors were more typical of the patients with phonemic paraphasia. The findings are interpreted in relation to a neuropsychological model of speech. It is suggested that phonemic paraphasia represents a breakdown mainly in the retrieval of phonological word patterns, while apraxia of speech is characterized predominantly by a disturbance in encoding phonological patterns into appropriate speech movements.

Articulatory additions to the classical description of the speech of persons with cleft palate.

Three types of compensatory articulation used by speakers with cleft palate and velopharyngeal inadequacy are described: the pharyngeal stop, the mid-dorsum palatal stop, and the posterior nasal fricative. These articulatory characteristics have not been previously reported in the literature. Each is defined radiographically to depict deviant place of production. Each is also described in terms of perceptually distinct speech characteristics. Production features of these articulatory compensations are contrasted and compared with those of the glottal stop and pharyngeal fricative. The use of compensatory articulation as replacements for target phonemes is distinguished from their occurrence as aberrant co-articulations with target phonemes. Additionally, phonetic symbols for use in narrow phonetic transcription are presented, and implications for speech remediation are discussed.
