Reproduction And Development
Gbogbo ọrọ náà
Human reproduction is a chain of precisely timed events: two specialised cells fuse, a single fertilised cell divides to build an entire embryo, and a set of hormones choreographs everything from the monthly cycle that makes fertilisation possible to the process of birth itself. This lesson sets out that chain accurately and in the correct anatomical and clinical language.
You will learn the structure of the male and female reproductive systems, how meiosis produces gametes, the hormonal control of the menstrual cycle, the events of fertilisation and pregnancy, the stages of birth, patterns of human growth, and the range of contraceptive methods available, including how IVF can help couples who cannot conceive naturally.
