Endometric thickness - 8mm
Right ovarian follicle(mm) - 12*11, 10*9
Left ovarian follicle(mm) - 14*12, 13*11, 14*11

Uterus measured 6.5*3.5*4.1cms
Right ovary measured 3.7*2.6*3.3cms
Left ovary measured 4.0*2.7*3.2cms

Can you please suggest when i should take hcg injection.

Brief Answer:
When the follicle is atleast 18 - 20 mm in size.

Detailed Answer:
Thanks for writing to us with your health concern.
See, basically HCG injection is given for rupturing the mature egg follicle.
It should be taken when the follicle is ripe for rupture, when it is ready to rupture.
That generally happens when the follicle is around 18 mm - 20 mm.
Follicle grows at the rate of 1 - 2 mm per day.
So around day 14, in a normal cycle, the egg reaches that size.
Continue follicular monitoring till the largest follicle is 18 - 20 mm.
That is the best time to take HCG injection.
Hope that helped you.
All the best
Please feel free to discuss further.

Brief Answer:
As below

Detailed Answer:
Have you taken such medications before ?
Well, I think you should have a scan tomorrow.
Either the follicular size will increase, or it will rupture by itself ( spontaneously ).
So wait for one more day.
Meanwhile start remaining sexually active please.
ANd yes, you need to lose weight also.
Take care.
What other investigations have been done so far ?
Has semen analysis been done ?
