Abstract

Purpose

To evaluate different factors that might affect the incidence of embryo aneuploidy in intracytoplasmic sperm injection cycles (ICSI).

Methods

One hundred and ninety ICSI cycles in conjunction with preimplantation genetic screening (PGS) were included. The influence of the following variables on the aneuploidy incidence was evaluated: (i) maternal and (ii) paternal ages, (iii) dose of FSH administered, (iv) dose of FSH per number of retrieved matured oocytes (FSH/MII), (v) serum 17β-oestradiol levels on the ovulation trigger day, (vi) aspirated follicles and (vii) retrieved oocytes.

Results

A total of 440 embryos were successfully biopsied, of which 240 were considered euploid and 200 were considered aneuploid. The paternal age (Slope: 0.2, p = 0.372), total dose of FSH (Slope: 0.2, p = 0.218), FSH/MII (Slope: 0.1, p = 0.296) and 17β-oestradiol levels (Slope: 0.2, p = 0.378) were not correlated with the presence of aneuploidy. However, the maternal age (Slope: 1.7, p < 0.01), aspirated follicles (Slope: 1.9, p < 0.01) and retrieved oocytes (Slope: 2.6, p < 0.01) were negatively correlated with the incidence of aneuploidy.

Conclusions

Even in older patients, lower oocyte yields may represent a more appropriate response to ovarian stimulation, allowing the most competent follicles and oocytes to develop and thereby reducing the occurrence of embryo aneuploidy.
