Sperm selection capacity of cervical mucus.

Area of Science:

• Reproductive biology
• Human fertility studies

Background:

• Infertility investigations require assessment of sperm and cervical mucus.
• Understanding the interaction between sperm and cervical mucus is crucial for fertility.

Purpose of the Study:

• To determine the morphological selective capacity of cervical mucus.
• To evaluate factors contributing to normal sperm presence in cervical mucus post-coitus.

Main Methods:

• Morphological examination of ejaculates and cervical mucus samples.
• Analysis of post-coital samples from 17 couples undergoing fertility investigations.

Main Results:

• Both sperm motility and the mucus's ability to select against abnormal sperm were observed.
• A high percentage of morphologically normal spermatozoa were found in cervical mucus post-coitus.

Conclusions:

• Spermatozoa motility and cervical mucus selectivity are key factors in post-coital test results.
• These factors contribute to the presence of normal sperm in cervical mucus, aiding fertility assessment.
