[Morphologic parameters of sperm. 1) Syndromes].

Area of Science:

• Reproductive Biology
• Andrology
• Human Fertility

Context:

• Assessing male fertility is crucial for couples experiencing infertility.
• Identifying reliable indicators of male fertility is an ongoing challenge.
• This study focuses on husbands of infertile wives to establish reference values.

Purpose:

• To establish reference values for sperm parameters in a
• normal
• male population.

Summary:

• Analyzed 23 cases of husbands of sterile wives, comparing them to a reference group of 839 patients with diminished fertility.
• Identified straight-line sperm motility as the most significant parameter for assessing male fertility.
• Developed seven distinct sperm abnormality profiles (syndromes) based on affected sperm components (head, midpiece, tail).

Impact:

• Highlights the importance of straight-line sperm motility for future automation and standardization in fertility testing.
• Provides a framework for classifying male infertility based on specific sperm morphology defects.
• Contributes to a better understanding of the etiological factors in male subfertility.
