Just had my first ultrasound on CD 5 and the Dr said my lining was a little thick, and that she wants to keep an eye on it.  She will check it again if I don't get pregnant, and  it is still thick, she wants to do a biopsy.

So what does a thick lining mean?  does it affect my fertility?

Thanks in advance!!!  Smile

I don't know about thick lining but I'm guessing since they're going to look into it if you don't get pregnant that it could affect your fertility.  The best person to ask about this would probably be your doctor...

I do know that if your lining is too thin it can affect your fertility (as is the case with me).  I had an endometrial biopsy that showed that my lining was several days behind where it should have been and my RE says that this is likely the reason I haven't been able to get pregnant.  

I hope someone else with experience about thick linings will chime in for you.  Good luck!

I think it might have to do with PCOS? 

Which the Dr didn't say I have PCOS or anything, but the only information I can find on thick endometrial lining is in relation to PCOS or uterine cancer.

a little thick shouldn't be too much to worry about.  Did the DR tell you how thick it was?

I will give you some background on my story and hopefully it will help you (and not scare you - as that's not my intention).

In June 2010, I started having major problems with my cycle.  An ultrasound in August 2010 revealed that my lining was 20 mm thick (about .78 inches)  It should have been about 6-10 mm (about .25-.6 inches).  I was referred to a specialist (obgyn) to deal with it. (where I live, you don't see an obgyn for routine gyne issues, you just see your gp - obgyn is usually only for gyne trouble or high risk pregnancy).  Anyway, when I saw the OBGYN in December, my lining was 24 mm (nearly 1 inch) thick.  My cycle was horrible (really heavy and painful).  The OBGYN did a biopsy and she discovered that I had complex endometrial hyperplasia with atypia.  Basically it meant that I had overgrowth (hyperplasia), and the atypia and complex part meant it was pre-cancerous growth.

I was referred to an Oncologist, who did a D&C and put me on Medroxyprogesterone to control the growth.  I just had another ultrasound last week and the lining is 8 mm (.3 inches) which is perfect.  I have a biopsy next week to see if the precancerous cells have disappeared - the oncologist thinks it has.

This is what my OBGYN and Oncologist said about thickness and fertility.  Having a thicker than usual lining does not mean that you can't conceive.  Nor does it mean that there would be problems with your pregnancy.  If it is too thick (such as mine was) there is a chance that it wouldn't implant because your body can't support all the lining and therefore you have near constant shedding.

What they did say is that there is a good chance that ovulation or conception won't happen simply because the overgrowth is typically caused by an overload of estrogen, and that will mess with your cycle and ovulation and the ability to maintain the pregnancy.

It really depends on how thick the lining is and how long it's been that way as to whether it would be a problem.  Check out endometrial hyperplasia to find out more about thick lining.  Chances are that you don't have the complex atypia part, so don't fret about that.    It is good that your doctor is aware of it and is keeping an eye on it.
