The prenatal period is the development period before birth with the development itself referred to as Gestation. With support from other sources, the integration of these two sources provide the brief in this paper

Biomedical technologies have made it possible to monitor the development of the fetus in the womb. Ultrasound and CT data provide appropriate images that have given the understanding of how a fetus develops in the womb from the first week until delivery. Nash, Bjerklie, Park and Cray (2002) give an account of how the fetus starts to develop within the first week, showing an image of nothing bigger than a grape until two months when much construction of organs including the brain, heart, stomach, umbilical cord, oesophagus, kidney, lungs, vertebrae and liver takes place respectively. This would also involve the development of the rib cage, ears and eyes up to around the 84th day when the fetus could be spotted even sucking its thumb. Mahmud (2005) critically evaluates these steps from fertilization, involving the formation of a single cell from the fusing of a sperm and ovum, a process that would most likely occur 14 days before the menstrual period. The scholar further categorizes the nine months into three stages: the germinal or ovum stage between day 10 and 14. embryonic stage between 2 and 8 weeks where the major body developments articulated by Nash take effect. and the fetal stage lasting to delivery when critical developments of an infant occur. This literature provides critical insights into how a child’s sex is determined from the pairing of sex chromosomes, such that when X-chromosome carrying sperm fertilizes an ovum, the resultant XX zygote pair would be female and Y-chromosome carrying sperm would form XY zygote, a male. Thus, technology has greatly contributed to the understanding of fetal development.
