Conception

Conception refers to the process by which a sperm fertilizes an egg to form a zygote, marking the beginning of pregnancy. This process involves several stages, including ovulation, fertilization, and implantation.

Ovulation

Ovulation is the release of a mature egg from the ovary. This usually occurs in the middle of a woman's menstrual cycle, around day 14. The egg then travels down the fallopian tube, where it can be fertilized by sperm.

Fertilization

Fertilization is the process by which a sperm cell penetrates the egg. This usually occurs in the fallopian tube. Once fertilization occurs, the fertilized egg, now called a zygote, begins to divide and grow into a cluster of cells.

Implantation

Implantation is the process by which the cluster of cells, now called a blastocyst, attaches to the wall of the uterus. This usually occurs about a week after fertilization. Once implantation occurs, the woman is considered to be pregnant.

Factors Affecting Conception

Several factors can affect a woman's ability to conceive, including age, health, lifestyle, and fertility issues. Certain medical conditions, such as polycystic ovary syndrome (PCOS) and endometriosis, can also affect conception.
