The study focused on understanding what attributes some sperm have that give them a competitive advantage over the millions of others competing for the same prize.
Challenges of Sperm Swimming
Sperm face numerous challenges during their race to reach the egg, as they must swim against the current of a fluid that resembles thick corn syrup.
The Physiological Impact of the Female Reproductive Environment
The study indicates that the complex female reproductive environment aids sperm in swimming efficiently and guiding them to their desired destination.
Effects on Sperm in the Fallopian Tubes
As sperm swim against the current in the fallopian tubes, they encounter obstacles such as strong flow and geometric constrictions that they must leverage to find their way forward.
The Impact of Viscosity on Sperm
The study showed that viscosity plays a more significant role than shear rate in influencing the tail movements that propel the sperm forward. When swimming in a viscous fluid, sperm reduce the strength of their tail beats and swim with smaller waves, making them more energy-efficient and capable of reaching the fertilization site faster.
Applications of the Study in Fertility Treatments
The study suggests that these findings could be used to develop fertility treatments where doctors select the appropriate sperm to be introduced to the egg. Using a more viscous medium that resembles bodily fluids may improve sperm cell selection and increase the chances of obtaining the best cells.
Future Studies
With the completion of this study, further research on animals is necessary to verify the findings and apply them to humans. Additionally, studies on animals should be conducted to affirm the proposed hypotheses.
