Why Does a Fertilized Egg Split?

The process of fertilization is as follows. Through sexual intercourse, sperm and egg meet and fuse to form a fertilized egg, which then implants and gradually divides to form an embryo and a gestational sac. Cellular differentiation gives rise to different cell groups, ultimately forming tissues such as connective tissue, neural tissue, muscular tissue, and epithelial tissue. Let's briefly delve into this topic.

The growth and development of organisms begin with a single fertilized egg. During development, the cells produced by cell division acquire different functions and undergo morphological and structural changes. This process is called cell differentiation. Cell differentiation leads to the formation of different cell groups, and groups of cells with similar morphology, structure, and function are called tissues. The basic tissues of animals and humans can be classified into four types: epithelial tissue, muscular tissue, neural tissue, and connective tissue.

a. Nausea: Some people may experience nausea or morning sickness symptoms in the first few weeks after conception. These symptoms can occur throughout the day and night.

b. Breast Changes: Sore, tender, and swollen breasts may indicate pregnancy. These symptoms can appear within a few days of conception and usually resolve as your body adjusts to the hormonal changes.

c. Fatigue: High levels of progesterone, a hormone, can cause feelings of exhaustion. This is a common complaint among pregnant women, and you may want to observe other symptoms to confirm your suspicions.

d. Increased Urination: After the fertilized egg implants in the uterine wall, it begins to secrete the hormone hCG (human chorionic gonadotropin). This hormone stimulates frequent urination, leading to an increase in the frequency of trips to the bathroom.

e. Bleeding or Cramping: Eight days after ovulation and implantation, you may experience mild pink or brown spotting, which may be accompanied by cramping. Although spotting can also occur during menstruation, it is not a true menstrual period but rather a result of the fertilized egg implanting in the uterine lining.
