Hey khonnikel.

Just so you know I am not a medical doctor. My name is a bit of a joke with my TTC thread because I help them out understanding their test results. I've studied a bit of anatomy so know quite a few of the latin terms.

So that having been said, I'll try to help you with your results:
When young female embryos are forming there are these two tube like things called mullerian ducts. Most of the time these ducts fuse (so become one structure), and the membrane between the two disappears creating one uterus. Sometimes however, the membrane doesn't completely disappear. Some of it remains. This causes a septate uterus. So a uterus with some of this membrane still intact. If it is at the bottom of the uterus it is called a subseptate uterus. The sub in this case is latin for below. Septate meaning seperated with a membrane.
From what I understand this does not always cause problems with trying to concieve. But it can. On the positive side from memory it can be fixed. So this is good. Most likely your OBGYN or fertility specialist will look more closely about how large the membrane is and go from there.

I haven't heard of secretory endometrium before. That having been said the endometrium is the lining of the uterus. This is what a fertilised egg implants into. But I have no clue about the secretory part of it.

Hopefully that helps you some.

Sounds like you've been trying to concieve for quite some time. Are you in any of the TTC threads? There are heaps of lovely ladies in them that are super supportive. Plus it's always nice to know that you're not the only one going through problems.

Have a good night
