Do ovary sizes indicate healthy follicle growth?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hello doctor,

On the 12th day of my period, my right ovary was 39x23mm, and my left ovary was 36x23mm, with an ET (endometrial thickness ) of 9mm. I want to know whether my egg growth is good in my ovaries.

Kindly help.

Hello,

Welcome to icliniq.com.

I can understand your concern.

Your ovary sizes (right: 39x23mm, left: 36x23mm) and endometrial thickness (ET: 9mm) on day 12 of your cycle provide useful information about your reproductive health. However, to assess egg growth (follicular development), we need more details about the follicle size, not just the ovary size.

Typically, during ovulation tracking, doctors look at dominant follicle size in one or both ovaries. A mature follicle ready for ovulation is usually around 18-25mm in size. If you had a follicle in that range, then your egg growth is on track for ovulation soon. Your endometrial thickness (9mm) is also a good sign, as a healthy lining for implantation is usually between 8-14mm around ovulation.

Suppose you are trying to conceive or monitor ovulation. In that case, you may want to check with your doctor if they noted a dominant follicle size or consider a follow-up ultrasound in a couple of days to confirm ovulation. Let me know if you have more details or questions.

I hope this helps.

Thank you.
