Thankfully sperm don’t need to ask for directions

Posted by Dr Sandy on in Fertility | 1922 Views | Leave a response

confused spermMen never ask for directions, so how do sperm manage to locate the egg ?

Human eggs, already understand the imperfections of the other half, so they have developed a sophisticated signally system. The system sends out the egg’s location, guiding the handsome prince in shining armour to find the egg. Once the egg is located, the signalling system helps the sperm pierce through the multiple layers to form a zygote which develops into an embryo.

Science learns the GPS co-ordinates

For years, scientist have been keen to understand the signalling system, suspecting that in some cases, infertility is caused by a lack of appropriate advertising, on the part of the lady.

The signalling system is a sugar chain with a very fancy name, the sialyl-lewis-x sequence (SLeX). SLeX ties the knot following SEX, to bring the sperm and the egg together to create a brand new being.

Understanding SLeX will be fruitful

Characterizing exactly how the sperm locates, then penetrates the egg’s sugar coat, is expected to help both stop and start pregnancies.

Starting pregnancies will require researchers to find ways to boost the signal, when it is missing or not “loud” enough. Helping the sperm to avoid swimming around in circles desperately searching for the elusive egg, will improve the odds of a couple falling pregnant.

Stopping pregnancies will require the development of jamming equipment. The sperm will keeping searching to no avail. Unable to find the egg, they will eventually succumb to exhaustion. The advantage of cutting the marketing campaign would be fewer hormone disturbances which often produce adverse effects.

The conception of an idea

It will be sometime before this big discovery around the human conception translates into science that can be used.

But is it good to know, the absence of the map reading gene will have no bearing on your ability to procreate. Baby making boils down to marketing not map reading.

That’s the curveball.

We focus so hard on lowering LDL…
we forget it’s doing a job.

And midlife is when these conversations start showing up —
cholesterol, statins, shifting risk.

If this is on your radar…
there’s a free Navigating the Middle Years bundle open right now.

50+ resources on midlife health, hormones and what’s actually going on.

⏳ Closes tomorrow

Hop inside, you'll find the link in bio.

I’ve spent a long time trying to figure out how to explain what I actually do in a way that feels honest — not salesy, not dramatic, and not simplified to the point of being wrong.

What I finally landed on is something I call Unlocking Better Body Chemistry.

It’s not a program or a protocol.
It’s a way of looking at health problems — especially metabolic ones — that focuses on why things aren’t responding, instead of just chasing symptoms.

Most people I talk to are already doing a lot of “right” things.
They’re just doing them without a clear understanding of how their own body is functioning.

This framework is how I make sense of bloodwork, symptoms, and context together — and how I help people stop guessing about what actually matters.

I’ve put it all into a page so it’s clear, grounded, and easy to read.

If you’re curious, you can read it here. (link in first comment)

Your body isn’t misbehaving.
Its clocks are out of sync.

Every cell runs a molecular timekeeper — CLOCK, BMAL, PER and CRY — driving your energy, appetite, sleep pressure and mood.

When those clocks drift, everything feels “off,” and people blame willpower instead of timing.
