[40] Then, the eggs are collected using an ultrasound-guided aspiration needle. Once the eggs are outside the body, they are mixed with sperm in a culture dish in the hopes of fertilization.
Human fertilization is the union of an egg and sperm, occurring primarily in the ampulla of the fallopian tube. [1] The result of this union leads to the production of a fertilized egg called a zygote, initiating embryonic development. Scientists discovered the dynamics of human fertilization in the 19th century. [2]
In these cases, egg freezing may be used to preserve eggs. [ 4 ] [ 5 ] [ clarification needed ] [ citation needed ] Those undergoing treatment with assisted reproductive technologies who do not consider embryo freezing an option often look towards oocyte cryopreservation as an alternative option.
Oviparous animals laying eggs with thick calcium shells, such as chickens, or thick leathery shells generally reproduce via internal fertilisation so that the sperm fertilises the egg without having to pass through the thick, protective, tertiary layer of the egg. Ovoviviparous and viviparous animals also use internal fertilisation.
Sexual reproduction is a type of reproduction that involves a complex life cycle in which a gamete (haploid reproductive cells, such as a sperm or egg cell) with a single set of chromosomes combines with another gamete to produce a zygote that develops into an organism composed of cells with two sets of chromosomes .
