Human Reproduction

Male and Female Reproductive Systems

Human reproduction is any form of sexual reproduction resulting in human fertilization. In humans, the reproductive phase starts after puberty.

Its involves,

Ø Gametogenesis

Ø Insemination

Ø Fertilization

Ø Implantation

Ø Gestation

Ø Parturition

Gametogenesis:

The development of haploid cells into gametes is called gametogenesis. Gametogenesis may differ between males and females. Male gametes are called sperm. In human males, for example, the process that produces mature sperm cells is called spermatogenesis.

Insemination:

Insemination is the deliberate introduction of sperm into a female for the purpose of impregnating or fertilizing the female for sexual reproduction. The sperm is introduced into the uterus of a female.

Fertilization:

Fertilization is the union of a human egg and sperm, usually occurring in the ampulla of the fallopian tube. The result of this union is the production of a zygote cell, or fertilized egg, initiating prenatal development.

Implantation:

In humans, implantation is the stage of pregnancy at which the embryo adheres to the wall of the uterus. At this stage of prenatal development, the conceptus is called a blastocyst. It is by this adhesion that the embryo receives oxygen and nutrients from the mother to be able to grow.

Gestation:

Gestation is the period of development during the carrying of an embryo inside viviparous. The average length of human gestation is 280 days, or 40 weeks, from the first day of the woman's last menstrual period. The medical term for the due date is estimated date of confinement (EDC).

Parturition:

Childbirth, the process of delivering the baby and placenta from the uterus to the vagina to the outside world. Also called labor and delivery.
