Infertility has a high prevalence in the general population, affecting 5 to 15% of couples in reproductive age. The assisted reproduction techniques ( ART ) include in vitro manipulation of gametes and embryos and are an important treatment indicated to these couples. It is well accepted that the implantation rate is positively influenced by the morphology of transferred embryos. However, we question if, apart from the assessment of embryo morphology, the number of produced embryos per cycle is also related to pregnancy rates in the first fresh transfer cycle.
To evaluate the clinical pregnancy rate according to the number of formed embryos and the transfer of top quality embryos ( TQEs ).
In a retrospective cohort study, between January 2011 and December 2012 , we evaluated women who underwent intracytoplasmic sperm injection (ICSI), aged < 40 years, andwith at least 1 formed embryo fresh transferred in cleavagestage. These women were stratified into 3 groups according to the number of formed embryos (1 embryo, 2-3 and ≥ 4 embryos). Each group was divided into 2 subgroups according to the presence or not of at least 1 transferred TQE (1 with TQE; 1 without TQE; 2-3 with TQE, 2-3 without TQE; ≥4with TQE; ≥4withoutTQE). The clinicalpregnancy rateswerecomparedineach subgroup based on the presence or absence of at least one transferred TQE.
During the study period, 636 women had at least one embryo to be transferred in thefirst fresh cycle (17.8% had 1 formed embryo [32.7% with TQEversus 67.3% without TQE], 42.1% of women had 2-3 formed embryos [55.6% with TQE versus 44.4% without TQE], and 40.1%ofpatientshad ≥4 formedembryos[73.7%withTQEversus26.3%withoutTQE]).The clinical pregnancy rate was significantly higher in the subgroup with ≥4 formed embryos with at least 1 transfered TQE (45.2%) compared with the subgroup without TQE (28.4%).
Having at least two available embryos and at least one TQE for embryo transfer are predictors of the pregnancy rates.

To evaluate whether women with endometriosis have different ovarian reserves and reproductive outcomes when compared with women without this diagnosis undergoing in vitro fertilization/intracytoplasmic sperm injection ( IVF/ ICSI), and to compare the reproductive outcomes between women with and without the diagnosis considering the ovarian reserve assessed by antral follicle count ( AFC ).
This retrospective cohort study evaluated all women who underwent IVF/ ICSI in a university hospital in Brazil between January 2011 and December 2012. All patients were followed up until a negative pregnancy test or until the end of the pregnancy. The primary outcomes assessed were number of retrieved oocytes and live birth. Women were divided into two groups according to the diagnosis of endometriosis, and each group was divided again into a group that had AFC 6 (poor ovarian reserve) and another that had AFC 7 (normal ovarian reserve). Continuous variables with normal distribution were compared using unpaired t-test, and those without normal distribution, using Mann-Whitney test. Binary data were compared using either Fisher's exact test or Chi-square (2) test. The significance level was set as p < 0.05.
787 women underwent IVF/ICSI (241 of which had endometriosis). Although the mean age has been similar between women with and without the diagnosis of endometriosis (33.8 4 versus 33.7 4.4 years, respectively), poor ovarian reserves were much more common in women with endometriosis (39.8 versus 22.7%). The chance of achieving live birth was similar between women with the diagnosis of endometriosis and those without it (19.1 versus 22.5%), and also when considering only women with a poor ovarian reserve (9.4 versus 8.9%) and only those with a normal ovarian reserve (25.5 versus 26.5%).
Women diagnosed with endometriosis are more likely to have a poor ovarian reserve; however, their chance of conceiving by IVF/ICSI is similar to the one observed in patients without endometriosis and with a comparable ovarian reserve.
