Genetics Expanded

After waiting two months for an appointment with a genetic counselor, E and I finally got in to see one this morning. As expected, they had the results on E's second genetic screening which confirmed his diagnosis of Y chromosome infertility due to an AZFb microdeletion.

They were fascinated with E and the fact that he has any sperm at all. With his genetic profile, he shouldn't be able to produce any sperm but has still had counts as high as 23 million. I would have liked to talk about the particulars more, but ultimately the end result is same, 20 million or 2, his non-motile swimmers are not usable.

The counselor got more info on our families but couldn't really suss out why we both have fertility problems. For a multitude of reasons, both our families are fairly small, and with such a small sample size it's tough to draw good conclusions. We can assume that E's infertility occurred de novo, as a fluke, while mine is still unexplained. They're testing me for fragile x syndrome as a last ditch explanation, since my family consists of all girls for two generations, but it's fairly rare to have a completely silent carrier and I don't have any of the symptoms or markers for the disease aside from my lack of eggies. E was almost late for work so I couldn't get my labs drawn today and will have to go back.

The counselor was really analytical which I appreciate, I approached the situation in the same manner and it made it really easy to connect with him. He understood my desire to have 5 years of egg fertility data to look at before making a decision (sadly impossible) and suggested we come up with a wall sized algorithm to predict all possible choices.  We went over pretty much every situation from E's sperm and my egg to egg and sperm donors. I think we have a somewhat solid plan of action.

**The Plan!**
1. Get my labs done for Fragile X and possibly CMV antibody. CMV antibody status is important for picking a donor. Done!
2. Decide if E is going to have the stimulated semen analysis to confirm for sure that his sperm is unusable.
      a. If E's sperm can't be stimulated, we go with a donor
      b. If E's sperm can be stimulated and is usable, we begin proceedings for IVF with ICSI
          - If E's sperm is usable, we will gender select so as not to pass on the mutation
3. Assuming E's sperm is unusable, we need to pick the donor. I want this to be mostly E's choice. I'm thinking a local sperm bank would be best so we can order the day before it's needed and courier it over.
4. Purchase donor sperm. We need to decide how many vials we want and how many will be stored.
5. Decide whether we're doing a stimulated cycle to see how I respond and try to get a better idea of my egg reserve, or proceed directly to a medicated cycle and IUI
6. Proceed with a medicated IUI cycle
7. Hopefully get pregnant!

While I definitely still have that I might cry sensation at the back of my throat, I am feeling a little better and more prepared. My biggest concerns are that I might be pushing E and not allowing him enough time to grieve. I've been really waring with myself on what we should do next and how we can balance my time crunch with his coping and emotional well being. Today, the genetic counselor said something along the lines of "people take fertility for granted, like gravity. It's just something that's there. But the reality is that for many people it isn't". I talked about how, cost aside, I wished our rolls could be reversed because I don't care about being genetically related to my child but E does/did.

Although we already knew it, the counselor said that not being able to have biological children is horrible and devastating and may always hurt, but that's normal and okay. I think that really helped E to hear this since he's been struggling with the idea that he may never be 100% okay with not having  genetically related children. I think he understands now that it's okay for that to always hurt a little, but it doesn't have to prevent us from having a family and kids that are his in every way that matters. He doesn't have to be thrilled about it, he just has to be at peace with it. I told E the only things I need him to be 100% on are 1. That he still wants children and 2. The donor we pick. As long as he's sure about these two things, I think we'll be okay.

AZFb Microdeletions and a Hysteroscopy

About a week ago E and I went to his follow up urology appointment and received the terrible news that he has a complete AZFb microdeletion. I've started to post a handful of times, but knowing that information hasn't provided us with the answers we need.

The AZF region is located on the long arm of the Y chromosome and there are three segments, the proximal, central and distal, or A, B and C.  Keeping in mind that these microdeletions are extremely rare, deletions in the B region are the most uncommon and have the worst prognosis. After getting my hands on every AZFb paper I could find, the literature concludes that men with complete AZFb deletions do not produce sperm. Men with C region deletions usually have low but usable counts, but B region deletions are an end of the line sentence.  Although E did have several 0 or near 0 semen analyses, he also had a 10 million, 23 million and 2 million, so he is very clearly producing sperm.

This leaves us with three possibilities:
- The genetic test was wrong, which is unlikely
- All the semen analyses were wrong, which is unlikely since they were done at 3 different labs
- E is an anomaly about whom they will write papers

We just repeated the genetic test but still need to schedule an appointment with the genetic counselor, and have a more detailed semen analysis done at a fertility clinic. We know if we were able to use E's swimmers that we'd have to select for girls, but I'm sure the counselor will want to go over it with us. That and the likelihood of donor sperm, which we are already prepared for.

For me, I had my Hysteroscopy done today, and while it was worse than I was expecting, it wasn't horrible. After the HSG I was picturing the Hysteroscopy as fairly similar, a little catheter threaded up, a numbing injection this time which I was sure would hurt, but nothing too terrible. Instead, there were at least 8 local anesthetic injections into my cervix and let me tell you they HURT, way more than I was expecting. I could feel those suckers all the way down my butt and thighs and they made me shake all over.

Then came the manual dilation of the cervix. Here I mistakenly assumed that since they'd done all those numbing injections, I wouldn't feel anything. Yeah, that was TOTALLY WRONG. I felt every single second of that and it hurt like a bitch. They ended up having to do it multiple times, including one time after they'd tried to put the camera in and it wouldn't fit. Once the camera was actually in, it wasn't horrible and it was pretty cool to see the inside of my uterus on the screen.

During my saline ultrasound, the doctor had seen a little piece of something could be a polyp but she thought it was more likely to be a bit of dislodged lining. It did it fact turn out to be lining, as I had a thick, fluffy lining, despite the progesterone I'd been taking for two weeks to thin it out, so no surgery necessary. Basically everything was normal, normal size, shape, color, it had perfect blood flow, no endometriosis, no polyps, a great lining, basically nothing physical that would prevent an egg from implanting.

At the end of the procedure, the doctor gave us a little print out of shots of my uterus. It felt like a stand in because we don't have a baby for ultrasound pictures, but we took it home for our records. You can't really see anything, just pink walls and fluffy lining.  It's scintilating.

Behold: My Insides

We also had a good chat with our doctor about possibly going with her clinic, since we have to go outside of Kaiser for IVF. I like that she is already familiar with our case and knows how the Kaiser system works, but we'll have to see if it's a good fit once we've met with the genetic counselor.
