What it is, and what it is not
Withdrawal means removing the penis from the vagina before ejaculation. It is not a fertility-awareness method: it rests on no knowledge of the cycle and does not combine with the other signs. It is filed with the natural methods for want of a better box.
Two claims are made about it, and both are wrong. It is not useless: done properly it clearly reduces risk compared with no method at all. It is not reliable either: its real failure rate puts it far behind every medical method.
Effectiveness
| Pregnancies per 100 women per year | |
|---|---|
| Perfect use (withdrawal in time, every time) | around 4 |
| Typical use | around 20 |
| No method, for comparison | around 85 |
In other words: one user in five is pregnant within the year in typical use. The gap between the two lines comes from the nature of the act itself — it depends on control at the exact moment control is hardest.
The pre-ejaculate question
The fluid released before ejaculation does not contain sperm produced at that moment. It can, however, carry out sperm left in the urethra after a previous ejaculation. Studies that examined such samples found motile sperm in some men only, not in all.
Practical consequence: urinating between two acts flushes the urethra and reduces that residual risk. It does not turn withdrawal into a reliable method, but it is simple and costs nothing.
When it makes sense
- Better than nothing, when no other method is available at the time.
- As a supplement to a fertility-awareness method, outside the fertile window.
- As a stopgap, while a chosen method is being arranged.
It makes no sense as a lasting main method for anyone who wants to avoid pregnancy reliably — and it protects against no sexually transmitted infection, pre-ejaculate being itself infectious.
If it fails
Late withdrawal, ejaculation at the vulva, any doubt: emergency contraception stays effective for several days, and the sooner it is taken the better. There is nothing to gain by waiting to see.
