Cyst ? Or follicle ?
A patient just sent me this query
I am 29 and trying to conceive for past 4 years.I have irregular cycles. My doctor prescribed me Injection recagon 100units for 6 days from 12-May-2014. On 11th day of cycle during follicle study I got dominant follicles on both ovaries and doctor prescribed to take orgamed capsules for 14 days This month I didn’t get my periods and HPT is negative and even checked with doctor , it is negative again and she prescribed me regestrone tablets for 10 days I have a clarification . If I got dominant follicles on both ovaries, where the follicles would have gone? As per my assumption it should be either fertilized or I should have started periods . I'm so confused. Please guide me
It’s very common for infertile women to be confused about reproductive basics. They often do not understand the relationship between menstrual cycle and ovulation; or the difference between follicles and eggs; or how follicles are different from cysts.
We need to go back to basics, to make sure there is clarity going forward. Otherwise this poor patient will keep on going round and round in circles, cycle after cycle !
This was my answer.
The reason your periods are irregular is because you Do not ovulate. This is called anovulation. Read more at www.drmalpani.com/articles/anovulation.htm.
This maybe because you have PCOD ( polycystic ovarian disease). You can read more about this at www.drmalpani.com/articles/pcod.htm.
You need the following medical tests.
1. Blood tests for you for the following reproductive hormones – FSH ( follicle-stimulating hormone),LH ( luteinizing hormone),PRL ( prolactin) , AMH ( anti-Mullerian hormone) and TSH ( thyroid stimulating hormone)
( to check the quality of your eggs). Do this from a reliable lab such as SRL ( www.srl.in);
2. A vaginal ultrasound scan which should check for the following.
a. Ovarian volume
b. B. antral follicle count
c. C. uterus morphology
d. D. endometrial thickness and texture
Please send me the detailed test results and medical reports . You can scan them in as a single Word file and email them to me. Patients with PCOD will typically have a high AMH level; a high LH:FSH ratio; increased ovarian stroma; and many small cysts arranged around the periphery of the ovary.
So what’s the difference between a follicle and cyst ? A cyst is basically a follicle which does not contain an egg. They both appear as hollow dark spherical objects in the ovary on ultrasound scans. Since we cannot make out if the structure we see on scanning contains an egg, this creates a lot of confusion in the patient’s minds .
To make matters worse, doctors often loosely refer to the follicles seen on ultrasound scanning as eggs. In reality, eggs are microscopic, and can only be seen in the IVF lab when the follicular fluid is examined under the microscope by the embryologist. While there are many kinds of cysts, the commonest kind we see is called a functional cyst, which looks exactly like a follicle , except that it’s larger.
Thus, when a mature follicle ( which contains an egg) fails to rupture at the time of ovulation, it collects fluid and becomes larger. This is called LUF syndrome. Read more at http://www.drmalpani.com/articles/luteinized-unruptured-follicle-syndrome-LUF-infertility.htm
A functional cyst ( so called because it is functioning and produces hormones) will often result in the period being delayed, as a result of the hormones it produces. This is why it may cause the period to be delayed. It’s possible to make this diagnosis by doing an ultrasound scan. The period can be induced with medications . These cysts will usually resolve on their own.
