Abstract

Objective: To investigate whether letrozole priming could be used efficiently in patients undergoing in vitro maturation (IVM) as compared with folliclestimulating hormone (FSH) priming. Materials and Methods: This is a retrospective analysis of 63 patients who underwent IVM due to the high risk of Ovarian Hyperstimulation syndrome (OHSS) (n=39), cancerophobia (n=16), and desire for IVM after failed in vitro fertilization attempts (n=8). Forty-two patients received FSH priming and 21 patients received letrozole priming. Results: The patients who had FSH or letrozole priming were statistically similar with respect to age, body mass index, duration of infertility, basal antral follicle count, serum anti-Müllerian hormone levels, and IVM indications (p>0.05 for all). When compared with the FSH priming group, the number of germinal vesicle oocytes, metaphase II and fertilized oocytes were significantly higher (p=0.003, p=0.001, and p=0.016, respectively), but the number of metaphase I oocytes was significantly lower in the letrozole priming group (p=0.002). The patients who received FSH and letrozole priming had statistically similar rates of implantation (33.3% vs 37.0%, p=0.709), clinical pregnancy (31.5% vs 33.3%, p=0.848), twinning (1.9% vs 3.7%, p=0.611), and live birth (24.1% vs 29.6%, p=0.682). Conclusion: Potential indications for IVM include patients with increased risk for OHSS and contraindication for hyperestrogenism. Aromatase inhibitors can be used to preserve the fertility of patients with estrogen-sensitive cancers. Letrozole priming appears to be an efficient approach in patients who undergo IVM, with likely less cost than FSH priming

Özet

Amaç: Bu çalışma, in vitro maturasyona (IVM) giren hastalarda letrozol kullanımının etkinliğinin folikül uyarıcı hormon (FSH) ile öncüllenmiş uygulama ile karşılaştırılmasını araştırmayı amaçlamaktadır. Gereç ve Yöntemler: Bu retrospektif çalışma, yüksek Yumurtalık Hiperstimülasyon sendromu (OHSS) riski (n=39), kanserfobisi (n=16) ve başarısız tüp bebek tedavisi sonrası IVM denemk isteyen (n=16) IVM’ye giren 63 hastanın analizidir. Kırk iki hasta FSH ile öncüllenmiş, 21 hasta ise letrozol ile öncüllenmiştir. Bulgular: FSH veya letrozol öncüllenmiş olan hastalar yaş, vücut kitle indeksi, infertilite süresi, bazal antral folikül sayısı, serum anti-Müllerian hormon seviyeleri ve IVM endikasyonları açısından istatistiksel olarak benzerdi (tümü için p>0,05). FSH öncüllenmiş grupla karşılaştırıldığında, letrozol öncüllenmiş grupta germinal vezikül oositleri, Metafaz II ve döllenmiş oositlerin sayısı anlamlı olarak daha yüksekti (sırasıyla p=0,003, p=0,001 ve p=0,016); ancak Metafaz I oositlerinin sayısı letrozol öncüllenmiş grubunda anlamlı olarak daha düşüktü (p=0,002). FSH ve letrozol öncüllenmiş hastalarda istatistiksel olarak benzer implantasyon oranları (%33,3’e karşı %37,0, p=0,709), klinik gebelik (%31,5’e karşı %33,3, p=0,848), ikiz gebelik (%1,9’a karşı %3,7, p=0,611) ve canlı doğum (%24,1’e karşı %29,6, p=0,682) gözlenmiştir. Sonuç: IVM için potansiyel endikasyonlar; artmış OHSS riski ve hiperinsulinizm için kontrendikasyon olmasıdır. Aromataz inhibitörleri östrojen sensitif kanserlerde fertilite koruma amaçlı kullanılabilmektedir. Letrozol ile öncülleme IVM tedavisine giren hastalarda etkin bir yaklaşım olarak görülmekte ve FSH öncüllenmiş tedaviden olasılıkla daha uygun maliyette olmaktadır.
