Navigating the complex world of fertility treatments can be overwhelming, especially when dealing with conditions like Polycystic Ovary Syndrome (PCOS). One drug that's been making waves in this arena is Letrozole, an aromatase inhibitor that's been suggested as a first-line drug for ovulation induction. But how does it work?

We might have learned about a 28-day menstrual cycle in biology class, but our reproductive systems are much more complicated and unique than that. There can be a huge variation in how long and regular our cycles are, particularly in those who suffer from PCOS.  

Some 70%-80% of women with PCOS experience infertility – an inability to conceive after at least 12 months of regular unprotected sex. It’s very common and extremely distressing but, thankfully, doesn’t mean that pregnancy is an impossibility (in fact, research has found that the majority of people with PCOS trying to conceive will fall pregnant and give birth without any fertility treatment at least once).

Between 70%-80% of people with PCOS experience infertility. Yes, you read that right.
