Fertilization in Human Reproductive System
Fertilization is the process of fusion of haploid male and female gametes to form a diploid zygote. In humans, fertilization occurs in the female reproductive system, and the process takes place in two regions, namely the ampulla and the ampullary-isthmic junction. Let us discuss in detail.
Ampulla
The ampulla is the dilated portion of the fallopian tube located near the ovary. It is the site where fertilization usually takes place. The following are the reasons why the ampulla is the preferred site for fertilization.
1. Optimal Conditions: The ampulla provides optimal conditions for fertilization, such as the presence of nutrients, appropriate pH, and temperature.
2. Sperm Survival: The sperm can survive for up to 5 days in the ampulla, increasing the probability of meeting the ovum.
3. Ovum Transport: The cilia on the epithelial lining of the ampulla help to transport the ovum towards the site of fertilization.
Ampullary-Isthmic Junction
The ampullary-isthmic junction is the narrowest part of the fallopian tube, located near the uterus. It is the site where the fertilized ovum enters the uterus. The following are the reasons why fertilization can occur at this site.
1. Sperm Migration: The sperm can migrate through the isthmus to reach the ampulla for fertilization.
2. Ovum Transport: The cilia on the epithelial lining of the isthmus help to transport the fertilized ovum towards the uterus.
Conclusion
In conclusion, fertilization in humans takes place in two regions, namely the ampulla and the ampullary-isthmic junction. The ampulla is the preferred site for fertilization due to its optimal conditions, sperm survival, and ovum transport. On the other hand, the ampullary-isthmic junction is the site where the fertilized ovum enters the uterus.
