INTRODUCTION
The complex topic of female genital tract is fascinating. The estimated
prevalence of Mullerian abnormalities is approximately 5 %, from mild
to severe, in the general population and increases up to 13 % in women
with infertility.(1) After the classification reported by ASRM in 1988,
de nuova abnormalities were reported and recently and in 2013 European
Society of Human Reproduction & Embryology – European Society of
Gynecological Endoscopy (ESGE – ESHRE) announced a new classification
in terms of uterine abnormalities.(2)
In the classification made by ESGE - ESHRE in 2013, dysmorphic uterus
was defined as; a - T shape, b - Infantile, c- Others and no sub -group
explanation for the group classified as the others. In the ASRM
classification, T shape uterine cavity is classified as class VII. There
is no detailed definition of Y shaped cavity and others in the
classifications designed by ESGE - ESHRE and ASRM. (2,3) (Figure 1)
Polycystic Ovarian Syndrome (PCOS) is the most common and studied
endocrine disorder of fertile-aged women, affecting approximately 5-10
% of the population. PCOS is characterized by several clinical
phenotypic presentations, including metabolic and reproductive issues,
mainly hyperandrogenemia, elevated serum anti-mullerian hormone (AMH)
levels, presence of oligomenorrhea / amenorrhea and insulin
resistance.(4)
The higher frequency of pregnancy complications, mainly preterm birth,
in PCOS patients than normo-ovulatory patients has been under discussion
for many years.(5–7) The data in the literature regarding the increased
preterm birth in PCOS pregnancies and our observations with intrauterine
cavity abnormalities in PCOS patients encouraged us to design this
research.
The hypothesis of our study is that ”the incidence of uterine
abnormalities, mainly Y shaped uterine cavity, in PCOS patients is
higher than in normo-ovulatory patients and this can be related to
maternal serum AMH levels”.
