Copulation in the male rat is accompanied by a progressive increase in both body temperature and hypothalamic temperature and, soon after ejaculation, by a rapid and selective decrease in hypothalamic temperature. We hypothesized that two changes occur in tandem within the vasculature of the nasal mucosa that contribute, respectively, to hypothalamic heating and hypothalamic cooling. The first ...

OBJECTIVE To explore the drug treatment for temporary ejaculation failure in couple undergoing assisted reproductive technologies (ART). DESIGN Case report. SETTING Andrology unit, center for reproductive medicine. PATIENT (S) Five patients suffering from temporary ejaculation failure during ART. INTERVENTION(S) Assisted reproductive technology. Semen samples were collected by masturbat...

OBJECTIVES To assess the cure rate of patients with premature ejaculation who underwent a treatment involving: 1) awareness of the pelvic floor muscles 2) learning the timing of execution and maintenance of contraction of the pelvic floor muscles during the sensation of the pre-orgasmic phase 3) pelvic floor rehabilitation (bio feed back, pelvic exercises and electrostimulation). MATERIALS AN...

This study aimed to assess the effect of genetic and seasonal interaction on semen quality in Artificial Insemination Center. A total 36,754 ejaculation records were evaluated. The dependent variable was which consisted volume, pH, concentration, abnormalities, motility fresh semen. independent variables age, season, number ejaculation. mixed procedure with Tukey–Kramer multiple comparison test...

PURPOSE This study tested whether individuals with at least 1 copy of the short (S) or long (L)(G) allele of the serotonin transporter gene-linked polymorphic region exhibit a greater incidence of premature ejaculation compared with L(A)L(A) individuals. MATERIALS AND METHODS The serotonin transporter gene-linked polymorphic region was genotyped in 82 men with lifelong premature ejaculation a...

The pelvic floor muscles are vital to male genitourinary health. Pelvic floor muscle training may prove helpful in a variety of clinical circumstances: stress urinary incontinence that follows prostate surgery, overactive bladder, postvoid dribbling, erectile dysfunction, ejaculation issues including premature ejaculation, and pelvic pain due to levator muscle spasm.

Recently, four premature ejaculation (PE) subtypes have been distinguished on the basis of the duration of the intravaginal ejaculation latency time (IELT). These four PE subtypes have different etiologies and pathogeneses. Genetic research on PE should consider the existence of these PE subtypes and the accurate measurement of the IELT with a stopwatch. Currently, three methods of genetic rese...

AIM To determine the prevalence and risk factors of erectile difficulties and rapid ejaculation in men in Croatia. METHOD We surveyed 615 of 888 contacted men aged 35-84 years. The mean age of participants was 54-/+12 years. College-educated respondents and the respondents from large cities were slightly overrepresented in the sample. Structured face-to-face interviews were conducted in June ...

Brain mechanisms that control human sexual behavior in general, and ejaculation in particular, are poorly understood. We used positron emission tomography to measure increases in regional cerebral blood flow (rCBF) during ejaculation compared with sexual stimulation in heterosexual male volunteers. Manual penile stimulation was performed by the volunteer's female partner. Primary activation was...

PurposeThis study explored the association of maternal age at menarche (AAM) with pubertal timing among girls and boys in Chongqing, China.MethodsPubertal development 1,237 children (542 695 boys) were examined half-yearly through inspection palpation from April 2014 to June 2019. Characteristics parents AAM collected by a parental questionnaire baseline. Maternal was used both as continuous ca...
