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:

1. Recruitment
   • Posters and outreach to enroll participants for the men’s and women’s studies.
2. Sample
   • Men’s study: 112 healthy male participants, age range 18–54.
   • Women’s study: ongoing (data collection in progress).
3. 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).
4. Main independent variable
   • Self‑reported number of orgasms per week (TSO).
5. 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).
