Microplastics and Intimate Toys: A Concerning Trend?

Australian and New Zealand Journal of Obstetrics and Gynaecology 2025

Summary

This perspective article raised concerns about microplastic exposure from intimate toys, noting that MNPs have been detected in the human endometrium and placenta through routes beyond inhalation and ingestion. The authors argue that direct mucosal contact with plastic-containing products represents an underexplored MNP exposure pathway.

Micro- and nanoplastics (MNPs) are ubiquitous in the modern world. Humans are exposed to MNPs through inhalation and ingestion, with a small amount of transdermal uptake. MNPs recently have been identified in the human placenta and endometrium. Although the source of placental MNPs is consistent with haematogenous spread, the presence of MNPs in the endometrium is more puzzling. As small particles can move retrograde from the vagina to the fallopian tubes, two unsuspected MNP sources are tampons and intimate toys. Intimate toys, in particular, might well be an important source of reproductive tract MNPs with intercourse as a potential co-vector.
