Understanding Luteinizing hormone

Nancy asks…
Ovulation Question, LH surge etc…..?
OK, so you get a postitive OPK so that means you will ovulate within 12 to 36 hours (i have
read)… so does that mean that the egg will come down the tube in that time and then you add
on another 12 – 24 hours for how long the egg survives in the fallopian tube, is that right??
so in total you are fertile for approximately 4 days after you detect your LH surge?
can someone clarify this please?
thanks very much.

so you
Pregnancy Advisor’s answers:
When you get a positive on an OPK you ovulate 12-36 hours after that time and then the egg is
viable for about 12 hours after you’ve ovulated.
So you could still be fertile for a few days after a positive OPK. However, you won’t be fertile
until you have ovulated, and you might ovulate the same day you get a positive OPK. It’s
1/6
2. impossible to tell and can vary each month!
While an egg is viable for 12 hours or so after ovulation bear in mind that it also takes time for
the sperm to reach the egg – that isn’t an instant process.
So yes in theory you could be fertile for up to a few days, but it’s more likely to be up to 2 days

Donna asks…
I am 41 and trying to conceive with controlled thyroid. Last month i
noticed low lh surge! ?
Little more detail my thyroid is controlled along with my bp. The last six months very stressful
due teminal ill parent. In that time my periods all on time like clockwork. My lh surge on time i
used the ovulation but it was really hard to conceive with all the things going on at the time. So
in august i thought i had missed my surge didn’t think anything of it this month i found it very
light. My gyno told me not to worry if i turn 41 because i still have a chance to get pregnant. I am
worried about the cost of clomid , the price and the effect of clomid and what exactly will it do.
My Endo doctor reccomends me to see a specialist right away once the thyroid is clearly ok. I
will know my test results in a week but don’t the eggs decrease after 41? i have managers, and
friends that are 43 and 45 that are pregnant help!! The reason we are pressing to conceive now
is because i have now lost a father and my husband lost his mother last year so the remaining
parents we would like to see a grandchild. Ivf seems expensive right now due to the recession
so any real answers will be very helpful!!
Oh yes and my period are on time 28 days on the dot to the point i know exactly what time it is.
When it is time for ovulation i get the lower pain near the ovaries right about the 9or 10th day
so i have been on time with the ovulation kits. The lines were dark up until this month. And i
don’t believe ( although i haven’t noticed to forget to count a day to use the kit) possible
because that was the month my father was buried September i don’t remember seeing

Pregnancy Advisor’s answers:
I’m sorry you’re going through this….and it’s good you’re talking to a gyno abuot this, if you
have regular cycles and ovulate then you have a good chance, you can try without meds for a
couple of months and if not successful try meds, you can also ask infertility specialists online for
free, and find others going through similar situations as you, try fertilityties.com
good luck!
Mandy asks…
When is the best time to check your LH Surge?
My bf and I are TTC #1. Since AF has always been irregular, we decided to use an OPK. When
should I test? In the morning, afternoon, evening? Please advise. This is my first time tracking
my ovulation and I want to make sure I’m doing it correctly…thank you in advance.

4. It is best not to test in the morning. My instructions say to cut off liquids at least two hours
before testing. Make sure to test at or near the same time everyday.
Lisa asks…
If more than one egg is released at ovulation what is the timing?
I have managed to conceive 3.5 days (approx 86 hours) after I picked up my LH surge on my
fertility monitor. I have read that LH lasts up to a maximum of 44 hours and the egg only lives
for 24 hours. I do not understand how this could be possible unless 2 eggs were released, with
one being released at a later stage. Can this happen?
Pregnancy Advisor’s answers:
The average length of the LH surge is 12-48 hrs but there are always special cases. You also
don’t know where in your LH surge you caught it. So it wouldn’t be far fetched for the egg to be
fertilized in the 3.5 days following your first positive. Now conception I thought usually referred
to the time the implantation occurred and I thought that was 5-10 days after fertilization. Hope
that helped in some way. Good luck and congratulations!!!

5. Sharon asks…
If I tested positive for an LH surge on an ovulation test, does this
mean I am 100% ovulating?
I tested today and it was positive! This is the first time ever, I am 25, I am so excited! I just want
to know if this means that I am for sure ovulating, i.e. the egg has or definitely will be released
into the fallopian tube in the next day or so.
Thanks- Brooke
Also, I have been on provera for about a week or so, does this have anything to do with it or is it
just coincidence? I am also due to follow up with clomid when the time comes.
Pregnancy Advisor’s answers:
I know exactly how you feel! I felt the same way when my fertility monitor first detected my
ovulation! It more than likely means you are ovulating! Sometimes with OPK’s, they detect the
LH surge, and then your body does not ovulate. LH is the hormone that triggers ovulation.
OPK’s predict the LH surge that triggers ovulation anywhere from 12-36 hours later. Having an
LH surge, and then not ovulating, is not super common. It sounds to me like you are going to
ovulate, so I’d start doing the BD ASAP, and get a hold of your Dr. Good luck to you, and lots of
baby dust for you!!!! It’s exciting, isn’t it??!!

6. Betty asks…
If I had an LH surge on Friday and I had sex Tuesday, Friday and
Sat, what are the chances that I conceived?
My urine test indicated an LH surge on Friday morning. My husband and I had sex on Tuesday
night, Friday morning, and Saturday afternoon. Did we have sex at the correct times? I know
you are supposed to have sex prior to ovulation. Doesn’t an LH surge indicate you are ABOUT
to ovulate or does it mean you are ovulating?? I’m hoping we understood correctly?? We are
really anxious to get pregnant!
Pregnancy Advisor’s answers:
Tuesday may have gotten it, but I’m afraid Friday and Sat. May have been too late. For me,
having sex about 24 hours after the ovulation stick lights up usually does the trick. If it didn’t
happen for you, better luck next time!!
