The sperm-cervical mucus contact test: a preliminary report
Fertility and Sterility
|March 1, 1976
Summary
Sperm antibodies cause infertility by impairing sperm movement in cervical mucus. This study shows sensitized sperm exhibit a "shaking phenomenon" upon contact with cervical mucus glycoproteins, explaining motility issues.
Area of Science:
- Reproductive Biology
- Immunology
Background:
- Sperm antibodies (spermagglutinins) are linked to infertility.
- Impaired sperm penetration and migration in cervical mucus are key issues.
Purpose of the Study:
- To investigate the mechanism of infertility caused by sperm antibodies.
- To identify the interaction between sensitized spermatozoa and cervical mucus.
Main Methods:
- Utilized a sperm-cervical mucus contact test.
- Examined motility patterns of normal and sensitized spermatozoa in cervical mucus.
Main Results:
- Infertility is associated with sperm exhibiting a shaking movement upon cervical mucus contact.
- This phenomenon occurs with both auto-sensitized sperm and normal sperm exposed to anti-sperm antibody serum.
- Sensitized sperm reacted specifically with the glycoprotein fraction of cervical mucus.
Conclusions:
- The "shaking phenomenon" is a key indicator of sperm dysfunction due to antibodies.
- This motility alteration results from an interaction between sensitized sperm and cervical mucus glycoproteins.

Spermatogenesis
123.8K
Spermatogenesis is the process by which haploid sperm cells are produced in the male testes. It starts with stem cells located close to the outer rim of seminiferous tubules. These spermatogonial stem cells divide asymmetrically to give rise to additional stem cells (meaning that these structures “self-renew”), as well as sperm progenitors, called spermatocytes. Importantly, this method of asymmetric mitotic division maintains a population of spermatogonial stem cells in the male...

Fertilization
92.1K
During fertilization, an egg and sperm cell fuse to create a new diploid structure. In humans, the process occurs once the egg has been released from the ovary, and travels into the fallopian tubes. The process requires several key steps: 1) sperm present in the genital tract must locate the egg; 2) once there, sperm need to release enzymes to help them burrow through the protective zona pellucida of the egg; and 3) the membranes of a single sperm cell and egg must fuse, with the sperm...

Sperm Structure and Semen Composition
11.9K
During ejaculation, males release around 2-5 milliliters of semen, which is a complex mixture of mature sperm and various fluids produced by accessory glands. The mature sperm cells measure approximately 60 micrometers in length and consist of a head, neck, midpiece, and tail. The head is flattened and tapered, measuring about 4 to 5 micrometers in length. It contains a nucleus with condensed chromosomes and an acrosome, a cap-like structure filled with enzymes essential for penetrating the...

Sperm Transport
3.8K
The journey of sperm from its origin to the point of ejaculation begins within the seminiferous tubules of the testis. Here, Sertoli cells produce fluid that propels non-motile sperm through a series of conduits, starting with the straight tubules leading to the rete testis. This interconnected network of tubules acts as the initial pathway for sperm, guiding them into the efferent ductules and then into the epididymis for maturation.
