PCOS (Polycystic Ovaries) and Ovarian Drilling.
Some
sort of ovarian surgery has been used to treat PCOs for the last 50
years.The surface of the ovary, also called the cortex, is where the
eggs are. This is a relatively thin layer covering the ovary. Beneath
this layer, in the mid portion of the ovary, is the tissue that makes
the androgens. PCO women have higher levels of androgens than women
without, and it is possible that these increased levels are what
interfere with normal ovulation. Androgens, by the way, are the
hormones that get changed into estrogens, so androgens are absolutely
necessary for normal repoduction, but in PCO the androgens are in
excess. Opening this layer and removing or destroying the inner tissue,
either by wedging out a piece of the ovary, or putting in multiple
holes using an electrical probe or a laser, changes the hormonal
balance of the ovary. It lowers the androgens and and somehow allows
for more frequent ovulation. These procedures are not frequently
performed because they do not always work, can cause scar tissue, and
there are other alternatives.
There are other ways to
stimulate ovulation, including clomid and FSH injections. Clomid works
to cause ovulation in women with PCO in most but not all cases. FSH
works in almost all cases. With FSH injuctions there is a high risk of
ovarian hyperstimulation, unless the starting dose is very low.
Certainly IVF is also an option.
Now some may ask why get
involved with fertility drugs and the cost of monitoring when a simple
surgical procedure will do the trick. In the case where the patient
cannot afford complex fertility treatments, but can get surgery, the
later does make sense. In addition some women just do not want to take
any form of fertility medication, so the surgery may be the best thing
for them. There can be complications from the laparoscopic surgery
including the usual bleeding, infection and injury to internal organs.
These are increased as the size of the patient increases, and more
severely PCO patient may be more obese. But more specifically, the
ovarian wedging or drilling can cause scar tissue and adhesions around
the ovary, decreasing the chance of conception even if ovulation
normalizes. This is is more common with wedge resection (taking out a
wedge) vs. ovarian drilling.
So before surgery is considered,
other methods of assisting ovulation need to be employed, such as
weight loss, along with medical interventions such as those listed
above, with the possible addition of prednisone and or metformin.
What
if there is anovulation from PCO and you are having a laparoscopy for
another reason such as pelvic pain, lysis of adhesions, endometriosis,
or fibroids. Should you have drilling or wedging when the doctor is in
there anyway? If the other methods of inducing ovulation are available
to you, I would not cut into the ovaries because of the possible scar
formation. Plus, wedging or drilling removes or destroys a large number
of follicles. Reducing egg number is just something I like to avoid.
If, however, you decide the drilling is best for you, the ovarian
surgery is an accepted method and may lead to pregnancy rather quickly.
Other PCO TopicsCysts from Clomid.
Clomid makes follicles, which are the fluid filled cysts that contain
the eggs. These follicles usually dissolve away 2 weeks ovulation but
sometimes, especially when there are more than one, it takes longer
than 2 weeks for them to go away. It is really rare that they are there
after 4 more weeks. I have not had a patient have a cyst that lasts for
months as a result of taking clomid. I have heard of such things, but
they must be quite rare. It’s common to use the birth control pill to
help make the cysts go away. Clomid causes the follicles to grow by
upping the FSH produced by the pituitary. Birth control pills lower FSH
levels so the theory kind of makes sense, but no one has really shown
going on the pill makes any of these cysts go away any faster.
When
should you come off metfomin, at the first pregnancy test or later in
the pregnancy? Every doctor has a different idea. There is a prevailing
thinking that PCO increases miscarriage rates. But there is at least
one good study showing there is no miscarriage difference between women
with PCO and women who normally ovulate. Plus there are other OK
studies calling into question an association between miscarriage and
PCO. However, there are a few studies in literature from outside the US
showing metfomin reduces miscarriage rates in women with PCO, plus it
reduces some pregnancy complications, including diabetes. This being
said, the continuation of metformin during pregnancy is not standard
among REs in the US.
Will provera increase your pregnancy rate
if you have irregular periods? If you have PCO and have very infrequent
periods, strongly consider taking to your doctor about clomid or FSH
injections. Provera, except in rare cases, will do nothing to get you
to ovulate. Even if you bleed after provera, you probably did not
ovulate, you just bled.
Egg quality clomid vs FSH? Probably similar.
Is
a clomid cycle that makes 6 follicles any different than an FSH cycle
that makes 6follicles? Probably not, providing the clomid has not
thinned out the lining of the uterus.
Sperm Topics:Sperm
quality 15 years after a vasectomy? Can really vary. In most cases the
sperm is fine. Now if the sperm will be extracted via a needle, even if
we consider the sperm quality excellent, we can only extract enough for
IVF. But in some cases the sperm quality is lower than expected, but
it’s rare that you can’t get a good IVF cycle out of what you find. If
there are any changes for the worse, they may be unrelated to the
vasectomy.
Can a CT Scan effect sperm? There is more and more
discussion about CT radiation exposure every day. However, at this
point, there is no evidence that a CT scan effects sperm counts,
motility, or functionality in any way.
Should you have icsi
with a sperm count of 12 million with 40% motility? This depends on how
many sperm are recovered from the sample after rinsing and spinning (I
know, sounds like there is a washing machine joke in here somewhere).
Sometimes you can recover more than 5 million motile, sometimes only 2
million. Every lab has it’s threshold and will make a decision based on
the number of motile sperm recovered. In our lab, 12 million and 40%
motility usually means no icsi, but I would need to reserve judgment
until we process the sample.
Is frozen sperm for iui less
active than fresh? It depends on 2 things. One is the numbers and
motility pre thaw. The more you have to start with the more you will
have in the end. The second thing is how the sperm survives the
freezing. Some really good samples just can’t handle the freezing and
thawing. We do not know why this is; there are just differences between
men that lead to different freezability. So the talk about frozen sperm
is not as good for iui as fresh would only be accurate if post thaw
counts or motility are low. Donor sperm has been put to the test.
Anytime we freeze sperm we do a post thaw of a very small amount. If
the post thaw is bad; bad donor. A good thawed sample is good; the good
living sperm have not been weakened. Maybe some dies off, but the
survivors are usually good survivors.
Most fertility doctors do not believe in the sperm penetration tests, especially when doing icsi anyway.
Miscarriage What
if you have had miscarriages, then surgery for a septum, and now can’t
get pregnant? Start with repeating the HSG and getting a semen
analysis. You never know, the septum may still be there, or maybe you
developed blocked tubes or even a male factor. Also get the day 3
bloods.
Repeat biochemical pregnancies (yes I still hate that term) require the same workup as for miscarriages.
Frozen EmbryosRe-freezing
embryos. There are a few papers showing that embryos can survive being
frozen, thawed and then frozen again. Logic dictates that this should
not be a first option, but there are cases where it seems like the
right thing to do. If you thaw more embryos than you want to transfer,
which is commonly done to select the best embryos, and surprisingly all
the embryos look great, then refreezing the extras may be a good option.
What
if you had a baby from a frozen cycle where 10 embryos were
transferred, and you want to get pregnant again but only have 5 left?
Even with your 1/10 success rate, 5 is plenty. In fact 5 may be too
many.
General TopicsIs an endometrium
of 14-16 mm too thick? Providing there is no hidden fibroid, polyp or
hyperplasia, that thickness is probably OK. And what about an estrogen
level that may be too high? There has always been talk about a too high
estrogen level and this goes back to studies in mice. However, I have
not see women whose problems are that their estrogen levels are too
high. Some women with thin linings are put on estrogen injections or
vaginal pills, and it is not uncommon to see levels over 2,000 in a
frozen or donor egg cycle. Some women undergoing IVF have estradiol
levels 5-10,000 (not a good idea for other reasons), and they have no
trouble implanting.
Do I endorse Egg Freezing? I don’t really
endorse anything. I am a fan of educating to the best of my ability,
and allowing my patients to make informed decisions. Egg freezing is
very promising, and some early studies show that is more successful
that we thought it would be. But, it is still relatively new and
expensive.
Both husband and wife diagnosed with
hypothyroidism. It’s possible, but get a second opinion just to be
sure. Some doctors over diagnose thyroid problems in everyone.
What
if you had some questions about your luteal phase, so you were placed
on progesterone but are still not pregnant? Don’t wait long. Talk to
your doctor about starting clomid because it too is a treatment for
luteal phase defect, and it may up your odds of getting pregnant as
well.
How long do you need to be on OCP’s prior to an IVF
cycle? In reality, you don’t need to be on them at all. One exception
is the OCP microdose (also called microflare) IVF protocol. Here the
recipe calls for ocps. But for all others, ocps are not necessary. Many
programs use them to time the cycle. This means the program wants you
to start on a certain day to time the retrieval/transfer. Or they want
you to start in a certain week because they may have lab personal
coming from the outside for a specified number of days. If you are
relatively young and a good responder, the length of time on the pill
probably does not matter. However if you are a marginal or poor
responder, pill use, especially prolonged, could lower your egg
production further.
