Menstrual extraction
vacuum aspiration technique

Menstrual extraction (ME) is a type of manual vacuum aspiration technique developed by feminist activists Lorraine Rothman and Carol Downer to pass the entire menses at once. The non-medicalized technique has been used in small feminist self-help groups since 1971 and has a social role of allowing access to early abortion without needing medical assistance or legal approval. ME usage declined after 1973, when Roe v. Wade legalized abortion in the United States. There has been renewed interest in the technique, in the 1990s and more recently in the 2010s, due to increased restrictions on abortion. In some countries where abortion is illegal, such as Bangladesh, the terms "menstrual regulation" or "menstrual extraction" are used as euphemisms for early pregnancy terminations.
Development within a feminist context
In 1971, Lorraine Rothman and Carol Downer, members of a feminist reproductive health self-help group, modified equipment found in an underground abortion clinic that was developed for a new non-traumatic, manually-operated-suction abortion technique. They took the thin, flexible plastic Karman cannula (about the size of a soda straw), and the syringe (50 or 60ml), and added a one-way bypass valve, to fix two main problems. The contraption could prevent air from being pumped into the uterus, and also suctioned uterine contents directly into the syringe, thus limiting the amount that could be removed. They added two lengths of clear plastic tubing, one from the cannula to the collection jar and another to go from the collection jar to the syringe.
This brief starts where responsible research should: with the source description of “Menstrual extraction” as vacuum aspiration technique. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as vacuum aspiration technique. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Oct 30, 2025. The linked authority identifier is Q2621784. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1971 and 1973.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
