Male factor infertility and ART.

Area of Science:

• Reproductive Medicine
• Andrology
• Infertility Management

Background:

• Male factor infertility management has historically relied on clinical experience rather than evidence-based guidelines.
• Assisted reproductive techniques (ART) are widely used, often as adjunctive treatments for male infertility.
• Limited evidence guides the current clinical practice for male factor infertility.

Purpose of the Study:

• To review the evidence-based approach to managing male factor infertility.
• To outline the indications and limitations of various ART for male infertility.
• To emphasize the importance of screening and informed consent for ART procedures.

Main Methods:

• Review of current clinical practices and available evidence for ART in male infertility.
• Analysis of success rates and indications for intrauterine insemination (IUI).
• Evaluation of in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) criteria based on sperm parameters.

Main Results:

• Intrauterine insemination (IUI) is a potential first-line treatment if >1x10^6 motile sperm are recovered.
• In vitro fertilization (IVF) may be considered after 3-6 failed IUI cycles.
• Intracytoplasmic sperm injection (ICSI) is recommended for severe oligozoospermia (<0.5x10^6 motile sperm) or surgically retrieved sperm.

Conclusions:

• ART offers viable options for male factor infertility, with specific indications for IUI, IVF, and ICSI.
• While ICSI outcomes are well-studied, long-term safety and hereditary implications require further investigation.
• Rigorous screening and comprehensive patient counseling are crucial before initiating ART for male infertility.
