Enhancing the Fertility Potential: A Case Report on the Management of Oligoasthenozoospermia Using a Microfluidic Device.

Low sperm count and motility in oligoasthenozoospermia present significant challenges to conception. This case report involves a couple, a 28-year-old female and a 35-year-old male, experiencing secondary infertility for four years. The male partner's habits of alcohol consumption and smoking were potential infertility factors. Semen analysis revealed a total sperm count of 10 million/mL, with total motility at 30% and progressive motility at 5%. The couple underwent intracytoplasmic sperm injection (ICSI), using advanced sperm separation techniques to isolate motile and morphologically normal sperm. Despite the suboptimal sperm parameters, this approach resulted in successful fertilization and pregnancy. The female partner's preparation involved a short antagonist treatment, leading to the retrieval of eight oocytes, seven of which were mature. A positive urine pregnancy test and ultrasound confirmed the pregnancy, with β-hCG at 798 mIU/mL. This case highlights the potential of individualized treatments in managing oligoasthenozoospermia, emphasizing their promise in improving assisted reproductive outcomes despite mixed research results.
