Abstract
Purpose
The purpose of the present study is to study the relationship between oxidative stress (OS) in semen, semen characteristics, and reproductive outcomes in oocyte donation intracytoplasmic sperm injection (ICSI) cycles.
Methods
OS was measured in 132 semen samples.
Results
OS levels were as follows: very high (1.5 %), high (43.2 %), low (30.3 %), and very low (25.0 %). Overall seminal parameters were as follows: volume (ml) = 4.2 (SD 2.1), concentration (millions/ml) = 61.6 (SD 59.8), motility (a+b%) = 47.4 (SD 18.0), and normal spermatozoa (%) = 8.2 (SD 5.1). Of the 101 cycles that reached embryo transfer, 55.4 % evolved in biochemical, 46.5 % in clinical, and 43.6 % in ongoing pregnancy. OS level does not relate to seminal parameters, fertilization rate, or pregnancy outcomes.
Conclusions
OS testing by nitro blue tetrazolium (NBT) in fresh ejaculate might not be useful for all patients. Reproductive results with young oocytes and ICSI do not seem to be affected by OS-level semen.
