Summary of "5 Orgasmen pro Woche: Normal?! Warum wir Sexualforschung brauchen (Mirjam Reidick – Science Slam)"

Talk overview

Mirjam Reidick (Science Slam) presented her PhD research investigating whether orgasm frequency — operationalized as Total Sexual Outlet (TSO), the number of orgasms per week regardless of how they are achieved — correlates with physiological (particularly brain-related) and psychological factors (mental and sexual well‑being). She reported preliminary descriptive results from a men’s study and described ongoing analyses linking orgasm frequency to brain measures.

Key preliminary finding

In the male sample (n = 112, ages 18–54) the average self‑reported orgasms per week ≈ 5, with many participants reporting 3–4 per week.
Analysis relating orgasm frequency to brain structure/function is ongoing; no definitive brain findings have been published yet.

Scientific concepts, measures and phenomena

Total Sexual Outlet (TSO): weekly number of orgasms regardless of context (masturbation, intercourse, etc.).

Main concepts and measures covered in the talk:

Self‑report sexual behavior and orgasm frequency.
Psychological measures:
- Sexual well‑being.
- General mental well‑being.
Cognitive testing:
- Working memory.
- Processing speed.
- Other cognitive domains (examples given).
Brain imaging:
- Structural MRI (gray and white matter volumes across regions).
- Functional MRI (BOLD activation / blood‑flow related measures).
- Practical note: participants were not asked to masturbate in the scanner to avoid motion artifacts.
Reproductive biology / semen analysis (WHO criteria):
- Sperm concentration (count).
- Sperm motility.
- Sperm morphology (normal forms vs. head/tail defects).
- Interpretation caveat: failing one WHO criterion does not necessarily imply infertility.

Recruitment and sampling issues

Recruitment through eye‑catching posters targeted at desired participant groups (separate men’s and women’s studies).
Anonymity concerns and potential reporting bias when collecting sensitive sexual behavior data.
Demographic differences can influence reported orgasm frequency (examples: younger men and partnered men tend to report more regular orgasms).

Study design / methodology

Study overview:

Recruitment
- Posters and outreach to enroll participants for the men’s and women’s studies.
Sample
- Men’s study: 112 healthy male participants, age range 18–54.
- Women’s study: ongoing (data collection in progress).
Data collected
- Questionnaires on sexual behavior and psychological well‑being.
- Cognitive performance tests (e.g., working memory, processing speed).
- Structural and functional MRI scans.
- Semen samples collected via ejaculate for sperm quality analysis (in collaboration with a urologist).
Main independent variable
- Self‑reported number of orgasms per week (TSO).
Analysis
- Multivariate approach correlating orgasm frequency with brain structure/function, cognitive and psychological variables, and sperm parameters (analyses currently in progress).

Additional notes and anecdotes from the talk

The presenter used humorous props (e.g., “brain sperm stickers”) and an illustrative participant report card labeled “Mr. Schwimmer” to explain sperm reports.
Mentioned cross‑cultural and linguistic tidbits about words for orgasm (anecdotal).
Emphasized the societal importance of sex research: informing evidence‑based sexual education and protecting sexual rights (the right to pleasurable, safe sexual and reproductive health; consensual relationships; sexual education).
