At the recent American Society of Reproductive Medicine’s 2016 Scientific Congress in Salt Lake City, a group of researchers shared some intriguing findings about infertility treatments. One study focused on using letrozole in conjunction with intrauterine insemination (IUI), shedding light on how the thickness of the endometrial lining can affect pregnancy rates.
The Role of Letrozole in Ovulation Induction
Letrozole is becoming a popular choice for women trying to induce ovulation, especially when traditional methods like clomiphene citrate (Clomid) might not be the best option. The idea is simple: confirm that mature follicles are ready, then proceed with timed intercourse or IUI to maximize the chances of conception. However, a key factor often discussed is the thickness of the endometrial lining, which some believe can influence implantation success.
Does Thickness Matter?
So, does a thicker lining really increase the odds of pregnancy when using letrozole with IUI? According to the study presented, while a thicker lining is generally thought to be beneficial, the results indicated that once the lining reached about 5 mm, the chance of getting pregnant didn’t significantly improve with increasing thickness. Interestingly, women with a lining of 5 mm had a clinical pregnancy rate of 17%, while those with 9 mm showed no better results. Researchers also found that the number of follicles and the motile sperm count at insemination played a more crucial role in determining outcomes.
Implications for Patients
For anyone navigating the complexities of fertility treatments, this research suggests that while having a decent endometrial lining is important, aiming for ultra-thick linings might not be necessary. Many patients fall comfortably above that 5 mm threshold, making the journey a bit less stressful.

Conclusion
In summary, the thickness of the endometrial lining is relevant but not as critical as previously thought when using letrozole with IUI. Factors like the number of follicles and sperm quality are more influential in achieving a successful pregnancy.
