Are semen parameters related to birth weight?

Area of Science:

• Reproductive biology
• Human fertility studies
• Developmental origins of health and disease

Background:

• Maternal nutrition during gestation is linked to offspring reproductive function.
• The impact of birth weight on adult male fertility in humans is not well-documented.

Purpose of the Study:

• To investigate the association between birth weight and male fertility parameters in adulthood.
• To determine if birth weight is linked to unexplained male subfertility.

Main Methods:

• Evaluated relationship between birth weight and sperm parameters (total count, progressive motility, DNA fragmentation) in subfertile and fertile men.
• Recruited participants from the ALIFERT study.
• Performed metabolic assays on blood samples.

Main Results:

• Birth weight was associated with increased sperm DNA fragmentation.
• A significant inverse correlation was found between birth weight and total sperm count.
• These findings highlight the importance of the in utero environment for male reproductive health.

Conclusions:

• Birth weight is an important factor influencing sperm quality and male fertility.
• The prenatal environment plays a crucial role in determining adult male reproductive function.
