Hello
Thanks for your query.
Siphene is 
clomiphene citrate.
It is a medication that stimulates the ovaries to produce egg follicles.
it is given to patients who have difficulties in regular 
menstruation and ovulation.
It is sometimes given to patients with unexplained 
infertility to increase chances of conception.
Before starting siphene, the following should be done :
1. Partner's semen analysis
2. 
Hormonal status and documentation of ovulation status
3. Assessment of fallopian tubes - ideally with 
laparoscopy, instead of HSG
You could go for one cycle of natural planning with follicular monitoring.
If ovulation is not proved, you can then consider taking siphene.
It does have its side effects, but it is indicated if required.
It does not impair your ability to conceive naturally, unless there is some pre existent problem.
Take care.
