Intracytoplasmic sperm injection (ICSI) offers hope for male infertility. This study shows ICSI successfully produced healthy births, indicating its future role in assisted reproductive technologies.

Area of Science:

  • Reproductive Medicine
  • Andrology

Background:

  • Intracytoplasmic sperm injection (ICSI) research began in 1990, with clinical application starting in 1993.
  • The study focuses on a Scandinavian program's experience with ICSI from 1993 to September 1994.

Purpose of the Study:

  • To evaluate the efficacy and outcomes of Intracytoplasmic sperm injection (ICSI) in treating male sub-fertility and other reproductive challenges.
  • To assess the fertilization, pregnancy, and delivery rates associated with ICSI.

Main Methods:

  • Clinical application of Intracytoplasmic sperm injection (ICSI) in 456 couples over 538 cycles.
  • Inclusion criteria: severe male sub-fertility, high antisperm antibodies, vas deferens blockage, neurological disorders, cystic fibrosis, and acrosome-deficient spermatozoa.

Main Results:

  • Overall fertilization rate was 59%, comparable to conventional in vitro fertilization (IVF).
  • Pregnancy and ongoing pregnancy rates per embryo transfer were 29% and 22%, respectively.
  • 36 healthy children were born from 29 deliveries with no major malformations reported.

Conclusions:

  • Intracytoplasmic sperm injection (ICSI) is a viable treatment for severe male sub-fertility and related conditions.
  • The program experienced high demand, suggesting ICSI will be crucial in future assisted reproductive technologies.
  • ICSI demonstrates a capacity to achieve healthy births, addressing significant challenges in male infertility.
