PCOS can not be diagnosed only on the basis of TVS. You need to undergo hormonal investigations like LH,Testosterone
and DHEAS to reach at diagnosis as you don't have clinical symptoms. 23*14 mm is size of rt ovary or size of a follicle in rt ovary is not clear. If there is anovulation
then you may need ovulation induction
. If you are overweight
then try to lose weight by diet control and exercise. Testing blood sugar levels will give an idea about need to start metformin. As your husband is oligospermic and diabetic,IUI will be better choice compared with timed intercourse. Don't worry there is a good chance of getting pregnant once ovulation is confirmed.
