UNASSIGNED: Postorgasmic illness syndrome (POIS) is characterized by allergic symptoms and flu-like illness after ejaculation. There are still no effective treatments for POIS.
UNASSIGNED: To report the first case of washed microbiota transplantation (WMT) to treat patient with POIS.
UNASSIGNED: Data were collected from a patient with POIS who had received 3 courses of WMT: self-rating scale of POIS symptoms, Self-rating Anxiety Scale, Self-rating Depression Scale, and Symptom Checklist 90. The patient\'s stool samples for 16sDNA sequencing were collected 1 month after WMT.
UNASSIGNED: POIS symptoms improved after WMT. Scores decreased from baseline after WMT: self-rating scale of POIS symptoms (before WMT, 16; after first, 16; after second, 8; after third, 9), Self-rating Anxiety Scale (45, 42.5, 37.5, 45), Self-rating Depression Scale (63.75, 58.75, 47.5, 50), and Symptom Checklist 90 (143, 140, 109, 149). Characteristics of the patient\'s gut microbiota changed. At the genus level, the relative abundance of beneficial bacteria increased, and some opportunistic pathogenic bacteria decreased.
UNASSIGNED: WMT may be an effective and safe choice for the treatment of patients with POIS by changing the gut microbiota of the host.

UNASSIGNED: Postorgasmic illness syndrome (POIS) is rare and includes a cluster of physical and cognitive symptoms that occur after ejaculation. The pathogenesis and effective treatments remain unclear.
UNASSIGNED: This study aimed to characterize the symptomatology of POIS, study the allergic response of autologous semen in patients and controls, and evaluate the effects of desensitization therapy.
UNASSIGNED: The clinical characteristics of 24 Chinese patients with POIS were analyzed. Skin prick tests, intracutaneous tests, and specific IgE detection were performed with autologous semen. Five patients were desensitized via subcutaneous injections of autologous semen.
UNASSIGNED: Evaluated outcomes included the clinical features of POIS; scores of the Self-rating Anxiety Scale (SAS), Self-rating Depression Scale (SDS), and visual analog scale (VAS) of symptoms; skin reactions; desensitization with diluted autologous seminal fluid; and the IgE reactivity patterns of immunoblotting and enzyme-linked immunosorbent assay in vitro.
UNASSIGNED: The most common symptom cluster was the general cluster, and the most prevalent symptoms were extreme fatigue and inattention. A total of 66.67% (14/21) of the patients had no symptoms or milder symptoms after nocturnal emission than after intercourse or masturbation. Of the patients, 87.5% (21/24) had psychiatric symptoms and 53.85% (7/13) had abnormal sex hormone levels. The SAS and SDS scores of the high and low VAS groups were significantly higher than those of the control group. Pearson analysis showed that the correlation coefficient between the SAS and VAS was 0.607 (P < .01) and that between the SDS and VAS was 0.490 (P < .05). The patients and healthy donors all had positive intracutaneous test results with their own semen, negative skin prick test results, and no IgE specific to autologous semen. Most patients (4/5) did not achieve ideal therapeutic effects with desensitization.
UNASSIGNED: Allergy is not the main pathogenesis of POIS, and desensitization with autologous semen is not effective for most patients.
UNASSIGNED: This project included the largest number of patients with POIS in China and assessed the allergic response to autologous semen and the effect of desensitization therapy. There is no objective method for evaluating the efficacy of desensitization with autologous semen.
UNASSIGNED: IgE-mediated semen allergy is not the main pathogenesis of POIS, and there is a positive chance that POIS is related to psychological factors. Most patients do not respond to desensitization with autologous semen, and POIS treatment should be individualized, especially in cases with uncertain causes.

UNASSIGNED: Postorgasmic illness syndrome (POIS) is a rare condition in which individuals develop generalized and flu-like symptoms after ejaculation. Several mechanisms and treatments for this disorder have been proposed but many questions remain.
UNASSIGNED: We sought to present a summary of literature to date and highlight common symptoms, associated features, comorbidities, and laboratory findings in a clinical sample of patients with POIS.
UNASSIGNED: We conducted a retrospective chart review of 6 patients with POIS in our clinic and presented compiled results.
UNASSIGNED: We identified newly described non-flu-like presentations, onset of symptoms with high states of arousal without ejaculation, and presence of psychiatric comorbidity in a majority of patients. We did not identify a postorgasm allergic response with bloodwork available.
UNASSIGNED: POIS remains a poorly understood condition that likely comprises a number of different clinical entities. Further research on a larger clinical sample is necessary to better characterize POIS and understand its biological and psychological basis.

Postorgasmic illness syndrome (POIS) is a rare and singular syndrome. About fifty cases have been reported in the medical literature. Through a clinical observation, we illustrate the first case diagnosed in Tunisia and the difficulties in the etiological diagnosis and the therapeutic management of this syndrome. Given the shortage of cases reported in the literature, the syndrome of POIS remains poorly identified and subsequently misdiagnosed. The clinical diagnosis is relatively simple, yet etiological and therapeutic questions remain to overcome.

Postorgasmic illness syndrome (POIS) is a rare syndrome of unknown etiology where patients experience distressing physical and psychological after ejaculatory sequelae.
To better characterize the epidemiology, symptomatology, disease course, and treatment of POIS, with specific interest placed on examining relationships between disease presentation and measures of disease burden.
A 30-item questionnaire was distributed to an online community of patients with POIS from June 2019 to January 2020. We assessed diagnostic criteria and clusters of symptomatology described in prior studies. Outcome measures include self-reported measures of symptom severity, disease burden, and behavioral changes. Statistical correlations were assessed with Pearson\'s chi-squared (χ2) and ordinal regression analyses.
The main outcome measures of this study are self-reported measures of symptom severity, disease burden, and behavioral changes.
The sample consisted of 302 men (mean age: 32.6 ± 11.4 years, mean age of onset: 19.1 ± 7.8 years) with 89% satisfying ≥3 diagnostic criteria. Common symptoms were difficulty concentrating (254, 84%), extreme fatigue (250, 83%), irritability (225, 74%), and muscle weakness (212, 70%). Common symptom clusters were general (219, 72%), muscle (137, 45%), and head (93, 31%). Common behavioral modifications were avoiding masturbation (215, 71%), schedule changes (213, 71%), and abstinence (186, 62%). Head and throat symptom clusters demonstrated worse disease burden outcomes. Professional medical advice was sought by 51% of participants. Attempted treatments included pharmacotherapy, vitamins, supplements, and herbs with variable efficacy.
This study further characterizes POIS, including how patients respond to the condition, how it is treated in the community, and presentations that may be associated with more severe disease.
This is the largest study to date that concerns patients suffering from POIS and includes a diverse, global population. Limitations include that the survey was only administered in English and within 1 online community, that results were self-reported, and that the response rate was low (32%).
Characterizing symptom cluster, but not number of diagnostic criteria, may offer prognostic value, and investigation to elucidate pathophysiology and potential treatments for POIS is necessary.

Postorgasmic illness syndrome (POIS) is a rarely described syndrome characterized by transient flu-like symptoms and cognition disorders. Recent studies suggest that immunogenic reactivity to autologous semen is the underlying mechanism in POIS. Our study is regarding a 30-year-old that visited our unit for an allergy consultation because he experienced malaise after ejaculations. Skin prick tests and intracutaneous tests with autologous diluted semen with negative results were performed. Immunoblotting and western blot of the patient\'s autologous semen showed negative results. To complete the study, we intended to rule out other possible causes such as urological, hormonal, or neuropsychiatric disorders. We present a case of POIS based on the clinical criteria that did not show an IgE mediated cause. In the case of our patient, we could not identify the underlying cause; however, we believe that the possible involvement of neurobiochemical mediators should be studied.
