After childbirth, many women can't feel their pelvic floor because the pudendal nerve that controls these muscles can be stretched during delivery — Allen and colleagues (1990) documented measurable nerve changes after vaginal birth. That's why 'just do your Kegels' often fails: an estimated 30–50% of women contract incorrectly with verbal instruction alone (Bump et al., 1991). Sensation usually returns first, and restoring it with neuromuscular electrical stimulation (NMES) before strengthening can make training more effective. This guide explains why sensation fades after birth and how to wake the muscle back up. Individual results vary.
It's one of the most common — and least talked about — experiences after giving birth: you're handed a leaflet that says "do your Kegels," you try, and… nothing. No sense of lift. No sense of squeeze. Just a vague numbness where control used to be. Many women quietly assume they're doing it wrong. Often, the real issue is that the signal between brain and muscle has been disrupted.
Your pelvic floor is a hammock — and childbirth stretches it hard
Picture a hammock of muscle slung across the base of your pelvis. It holds your bladder, uterus, and bowel, and it's what keeps you continent when you laugh, lift, or sneeze. During a vaginal delivery, that hammock — and the nerves woven through it — can stretch to more than three times its resting length to let your baby pass.
That degree of stretch doesn't just tire the muscle. It can temporarily injure the pudendal nerve and its branches, which carry both the "move" signals to the muscle and the "sensation" signals back to your brain. Studies using nerve conduction testing have found measurable, usually temporary, changes in pudendal nerve function in a substantial share of women after vaginal birth (Allen et al., 1990; Snooks et al., 1984).
Why Kegels often fail in exactly this situation
Kegels assume two things: that you can locate the right muscles, and that you can feel whether you're contracting them correctly. Research has repeatedly shown that a large share of women — by some estimates 30–50% — perform pelvic floor contractions incorrectly when given only verbal or written instructions, often bearing down instead of lifting (Bump et al., 1991).
Now add reduced sensation after birth. You're being asked to find and squeeze something you can barely perceive. It's a bit like being told to wiggle a toe that's gone to sleep: the instruction is fine, but the feedback loop you'd use to follow it isn't online yet.
Sensation comes back — but it often needs a prompt
For many women, pelvic floor sensation gradually returns over weeks to months as the nerves recover. But "gradually" can be frustrating, and muscles that aren't being recruited in the meantime tend to weaken further. This is where giving the system an external nudge helps.
Neuromuscular electrical stimulation (NMES) takes a different route than Kegels. Instead of relying on you to find the muscle, it sends gentle electrical pulses that make the muscle contract directly — and just as importantly, those contractions feed sensory information back up to your brain. In other words, it can help re-establish the very feeling that lets you take over voluntarily later.
Key takeaways
- After childbirth, reduced pelvic floor sensation is common and usually stems from nerve stretch, not personal failure.
- You cannot reliably contract a muscle you can't feel — which is why early Kegels often seem to "do nothing."
- Re-establishing sensation first, then strength, is a more logical order than strength-first.
- Electrical stimulation can prompt both contraction and sensory feedback when voluntary effort isn't landing yet.
What a sensible recovery order looks like
- Awaken — restore the feeling of the muscles so your brain re-maps them.
- Activate — get reliable, correct contractions happening (with help, if needed).
- Build — once you can feel and fire the muscles, layer in strength and endurance work.
PelviLift™ was designed around exactly this order. It uses low-frequency micro-pulses to wake up sensation and produce guided contractions at home, so that the strength work your body — or your pelvic floor physiotherapist — builds on top has something to stand on. It doesn't replace skilled care; it gives the muscle a way back to the conversation.
Frequently asked questions
Is it normal to feel numb after giving birth?
Reduced or altered sensation in the pelvic floor is common after vaginal delivery and usually improves over weeks to months as stretched nerves recover. Persistent numbness, pain, or loss of bladder/bowel control should always be checked by a clinician.
How long until I can feel my pelvic floor again?
It varies widely. Many women notice sensation improving within the first few months. Active re-training, including electrical stimulation that prompts contraction and feedback, may help you reconnect sooner, but timelines are individual and not guaranteed.
Can I use electrical stimulation right after birth?
Not immediately. Internal pelvic floor stimulation should only be used postpartum after your OB-GYN or midwife has cleared you, especially after tearing, stitches, episiotomy, or ongoing pain.
Reconnect first. Then strengthen.
PelviLift™ uses gentle NMES micro-pulses to wake up sensation and guide correct contractions at home — the bridge between "I can't feel it" and real strength work.
