The process of embryogenesis begins with an egg or ovum being fertilized by a sperm cell to form a zygote. The zygote is a single diploid cell, which will ultimately multiply through mitotic ...

Embryology is the study of development of an embryo from the stage of ovum fertilization through to the fetal stage. The ball of dividing cells that results after fertilization is termed an ...

Mature egg cells, or oocytes, are essential for fertilization in assisted reproductive technologies. However, some 'denuded' oocytes, or those lacking the protective granulosa cell layer, fail to ...

Ovulation: When the ovaries release a mature egg that is ready for fertilization. Ovum: An egg. Pelvic Inflammatory Disease (PID): Inflammation of the uterus, fallopian tubes, and ovaries due to ...

If the egg your ovary produces is fertilized, the corpus luteum progesterone production continues for several weeks. Without fertilization, the corpus luteum stops working in a few days and ...

Scientists are getting closer to the possibility of making a new person from skin or blood cells – without the need for sex. This approach goes well beyond in vitro fertilization, which combines ...

New work by scientists in the U.S. and China shows how a fertilized egg cell, or zygote, hits ‘reset’ so that the newly formed embryo can develop according to its own genetic program. The study was ...

A primary parameter before opting for egg freezing is the assessment of ovum. The production and health of egg cells can be different for women even at the same age. For example, for two women who are ...
