One-woman pharmacy, Redux

Now that we have the green light for IVF, I finally trekked over to the pharmacy and picked up the rest of the drugs for my protocol. Here’s the loot this time:

Between Dr. Y’s sketchy (in my favor) billing and two hefty manufacturer coupons, I got quite a discount. Even with the discount, though, the grand total was quite a bit more than for my IUI drugs:

$1335

From a chemical standpoint, this list includes 8 small molecule drugs, 4 protein drugs, and one peptide (ganirelix) that is pushing the upper limit of what I’d usually call a small molecule. (I usually give 1000 atomic mass units as the cutoff; ganirelix has a molecular weight of 1570 amu…)

Here are the structures and modes of administration for my drugs:

Notice anything?

The small molecules tend to have more appealing modes of entry (often pills). Protein and peptide drugs tend to involve needles, for reasons I explained in a previous post.

I also found the biological source of many of these drugs interesting. (Note: If you’re using any of these drugs and are easily grossed out, or are philosophically opposed to Genetically Modified Organisms, you may not want to keep reading!)

Testosterone was originally discovered by painstaking isolation from bull testicles. The yield was paltry, though – just 20 milligrams from 40 pounds of testicles. (I’m trying not to think about how many bulls had to be emasculated to get 40 pounds of testicles…) Thankfully, nowadays testosterone – along with most other steroid drugs – is made semisynthetically from steroids isolated from plants (often soybeans or Mexican yams). In other words, chemists isolate a similar plant steroid and perform chemical reactions in a laboratory to convert it to the desired human hormone. Drug companies sometimes use the term ‘bioidentical’ to emphasize to non-chemists that hormones that are made semisynthetically are exactly the same – chemically and biologically – as the ones produced in your ovaries (or testicles…)

Menopur is a mixture of FSH and LH purified from the urine of postmenopausal women (hence its name; think Menopausal urine…) Historically this urine came from nuns living in convents in Italy, though I’m not sure if that’s still the case.

Pregnyl is also urine-derived, but presumably not from nuns… Pregnyl is purified hCG from the urine of pregnant women.

Follistim, on the other hand, is made from recombinant FSH (Follicle stimulating hormone) produced in Chinese hamster ovary (CHO) cells. This means that scientists copied a piece of human DNA – the blueprint that tells our cells how to make the FSH protein – and put it into the hamster cells. In effect, they hijacked the hamster cell’s protein factory and programmed it to produce large amounts of human FSH protein. (Don’t worry, the hamster cells now grow in Petri dishes; nobody is manufacturing protein in live hamsters…)

Omnitrope is also made from recombinant DNA technology, but in E. coli bacterial cells instead of hamster ovary cells. Unlike FSH (which is a challenging-to-make glycoprotein requiring sophisticated mammalian cell machinery), growth hormone is relatively easy to make. The human DNA ‘blueprint’ for growth hormone can be put into Escherichia coli cells and the bacteria cells produce the hormone for us.

I think I’ll stop there. If you want to know more about the chemistry of these drugs, you might check out my previous posts about the structures of FSH, LH, hCG and Clomid; doxycycline; aspirin; testosterone and estradiol (in the context of my current IVF cycle, or of what makes them steroids); the role of estradiol in predicting ovulation with the Clearblue fertility monitor; how hCG is detected in home pregnancy tests; or the significance of FSH and estradiol for diagnosing infertility.

Roid Monkey

So, on Monday I started rubbing Androgel on my upper arm each morning…and taking two Estrace (orally…phew!) each night. This is the hormone priming step of my IVF protocol. Add these to the Pulmicort inhaler that I use to keep my asthma under control and the progesterone that my corpus luteum is dutifully excreting, and you’ve got quite a steroid soup warming in my innards… I keep checking in the mirror for facial hair, bacne, or increased muscle mass. Aside from my pesky chin hair (excuse me while I find my tweezers…erm…got it!) I haven’t noticed anything.

Speaking of progesterone, I’ve relapsed into another of my pre-IUI TTC habits, namely, charting. I keep track of each morning’s BBT (basal body temp) measurement, my CBFM (ClearBlue Fertilility Monitor) reading, any eggwhite sightings, and sexual encounters on a little paper chart on my nightstand. Recording it on the paper chart has a certain old-school charm about it, but can be a bit tricky to analyze and doesn’t quite satisfy my appetite for data.

Enter FertilityFriend. I type in my data to this website and it uses an algorithm that incorporates the data from my temperature, cervical fluid, fertility monitor, and OPK (when I use it) to determine when I ovulated. Actually, there’s a ridiculous amount of other data I could enter, but even a data junkie like me has to draw the line somewhere…

charts aMy paper chart for this month (left), and the FertilityFriend version, with est. ovulation shown as a red vertical line (right).

If you spring for the VIP membership (or if you are a new member, in which case you get a free ‘teaser’ VIP membership), the website will evaluate how well you timed intercourse. C and I apparently did ‘Good’ this month

ImageAnother feature of the VIP membership is that it will overlay up to 7 charts and show you the average BBT pattern. I’m not sure what this would be useful for, but it looks pretty cool:

The average line (in blue) eliminates some of the noise of individual monthly charts to reveal a general trend of low temps pre-ovulation, followed by progesterone-elevated temps post-ovulation, which drop off just before the next cycle start (bonus benefit of charting – no surprise visits from AF!)

 

And this brings me to my newest dilemma: when to pick up my meds. Obviously, I already have some of them (including the Androgel and Estrace), but there are still ~$1K-worth of meds that Kaiser pharmacy doesn’t carry, which I have to pick up. If it weren’t for traffic, I would have picked them up the day Dr. Y prescribed them. But now that there is a chance – however miniscule – that I might be pregnant, I can’t bring myself to shell out that $1K until I’m sure I’ll need it…

So it’s one more thing on my ‘to do’ list. If FertilityFriend is right about my ovulation date, and if I follow my usual luteal phase of 11 days, then AF should arrive on Monday, and I can swing by the pharmacy after that, with plenty of time before I need those particular stims… On the other hand, maybe I should wait longer – until my baseline ultrasound (next Thursday) to make sure there are any follicles to stimulate with those drugs…yes, I think that makes more sense.

It’s a plan! And thank you, bloggy friends, for inspiring me to think this through, and patiently reading while I do. 🙂 Yet another perk of blogging…it forces me to think before shelling out C’s hard-earned money!

 

p.s. Welcome ICLW visitors! You can read my TTC resume here, but in brief: I’m a 34-year-old chemistry professor with diminished ovarian reserve, who has been TTC for about 15 months, including one missed miscarriage at 9 weeks. After 1 unsuccessful round of IUI, we are moving ahead with our first IVF next month. I use this blog as a form of therapy, and as a repository for interesting chemistry (and biology) that I learn along the way!
