So it’s no surprise that many individuals affiliate labor progress with one figuring out factor- cervical dilation. Nonetheless, there may be one other key component to assist resolve when to begin the precise birthing of the baby- station!
What Is Station and Why Does It Matter?
Station refers back to the child’s place in relation to the ischial spines of the birthing particular person’s pelvis. The ischial spines are small bony protrusions that may be felt throughout a vaginal examination to evaluate the child’s descent. (Please resist the urge to test this your self!)
- If the child’s head has not but descended into the pelvis, it’s measured in detrimental numbers from -4 to -1.

- Because the child strikes additional down, it’s measured in optimistic numbers from +1 to +4, with +4 indicating crowning.
Understanding the child’s station may help decide one of the best time to begin pushing, moderately than relying solely on dilation.
The Fetal Ejection Reflex, Ferguson Reflex and Medicated Births
Some folks expertise an uncontrollable urge to push—one buddy described it as “vomiting out of her vagina”. This highly effective, involuntary physiological response is named fetal ejection reflex coined by French obstetrician Michel Odent.
The Ferguson reflex and the fetal ejection reflex are associated however distinct physiological responses throughout labor:
- Ferguson reflex: This can be a neuroendocrine reflex triggered when the child’s head presses on the cervix and vaginal partitions, stimulating stretch receptors. This strain alerts the discharge of oxytocin, which will increase the energy and frequency of contractions. It’s a part of the suggestions loop that helps labor progress.
- Fetal ejection reflex: it is a extra intense, involuntary expulsion of the child, usually seen in undisturbed, unmedicated births. It’s characterised by highly effective, uncontrollable pushing efforts—usually described because the physique taking up. It’s much less about hormonal suggestions and extra a few sudden, instinctive motion to beginning the child.
In brief, the Ferguson reflex helps ongoing labor, whereas the fetal ejection reflex is a dramatic, usually closing push to get the child out.
When somebody has an epidural, each the Ferguson reflex and fetal ejection reflex will be considerably dampened and even utterly inhibited because of the numbing impact on the decrease physique and pelvic nerves.

- Preserve vitality—no pointless early pushing.
- Cut back cut-off dates imposed by hospital insurance policies.
- Improve the possibilities of a vaginal beginning by permitting the physique to do the work naturally earlier than participating in energetic pushing.
Key Takeaways
- Dilation is barely a part of the labor progress equation—station is equally necessary.
- The Ferguson reflex triggers an involuntary urge to push, however medicated births might not expertise this.
