Impact of Maternal Hormone Profile and Paternal Sperm DNA Fragmentation on Clinical Outcomes Following Assisted Reproduction.

Background: Success of assisted reproductive techniques depends on multiple factors including maternal endocrine status, hormonal balance, and paternal sperm quality. A comprehensive pre-treatment evaluation allows better prediction of outcomes and avoidance of unnecessary procedures and expenses.

Methods: To examine the impact of female hormonal profiles and sperm DNA damage on the success of assisted reproduction, medical data were extracted from the clinical records of infertile couples including couples' age and levels of maternal anti-Mullerian hormone (AMH), follicle-stimulating hormone (FSH), luteinizing hormone (LH), and prolactin (PRL), as well as the DNA fragmentation index (DFI) in men.

Microfluidic chips as a method for sperm selection improve fertilization rate in couples with fertilization failure.

Purpose: Sperm quality plays a vital role in successful fertilization and pregnancy. Patients with fertilization failure (total failure or low-fertilization rate) despite having normal semen parameters are a challenging group whose sperm cannot fertilize the oocyte via the intracytoplasmic sperm injection (ICSI) technique. Microfluidics is offered as a new method for proper sperm sorting.
