Is Letoval (letrozole /femara) advisable for ovulation induction?

[kv5747]

A brief summary about my condition- had a chocolate cyst in left ovary removed Nov 2008 through laparascopy. After that I was given 3 Depo Provera injections one a month for 3 months. Last shot was in Jan 2009 and I didnt get my periods until June 2009. I only had 2 periods June and July and not after that, even those, I wasn't ovulating. Last month went through a HSG and my tubes are all normal. But due to the Depo provera other than problems with getting periods, I also have some liver problems- high counts of SGOT and SGPT. So whatever meds are to be given to me, this has to be borne in mind.

Now, as next step there are two suggestions:
1. Take a combination of Estrogen Progesterone tables for 28 days, wait for my period to come back, then further tests to be done.

2. Take Letoval for 5 days, end of which I will either be ovulating or end up having periods and take it from there.

Of the two, my research shows that Letoval is an anti cancer drug and has been widely discouraged from being used for ovulation induction.  PLEASE ADVISE...I;m getting quite anxious and worried...
