Gametogênese: Estágio Fundamental Do Desenvolvimento Para Reprodução Humana

Abstract: RESUMO:A reprodução é o mecanismo essencial para perpetuação e diversidade das espé-cies, assim como para a continuidade da vida. Os gametas são os veículos de transferência dos genes para as próximas gerações. A gametogênese pode ser caracterizada por três etapas distintas denominadas multiplicação (mitose), crescimento e maturação (meiose), que se diferenciam em vários aspectos na espermatogênese e na oogênese. A oogênese diferencia-se da espermatogênese na ocorrência do processo ao longo da vida do indivídu… Show more

“…Gametogenesis is the process that produces the male and female gametes and is related to the perpetuation of the species (ARAÚJO, 2007). In female, the gametogenesis occurres in the ovaries and is called oogenesis, whereas in male the same process occurres in the tests and it is known as spermatogenesis (KOEPPEN; (CREASY et al, 2012).…”

“…Spermatozoa is a germ cell derived from spermiogenesis, a morphological differentiation of spermatids in spermatozoa. Structurally, the spermatozoa can be divided into: head -contain the nucleus and acrossoma, where several fundamental enzymes are present at the time of fertilization of the female oocyte; intermediate piece -represented by the mitochondrial sheath, responsible for providing electrical energy (ATP) for the motility of the flagellum; and tail -essential for gamete locomotion to the site of fertilization (ARAÚJO et al 2007;MONTANARI, 2013). According to Moore and Persaud (2000), the complete process of spermatogenesis in humans, from spermatogonia maturation to spermatozoa formation, lasts approximately two months.…”
