HD FS 102 Lecture Notes - Lecture 1: Artificial Insemination, Umbilical Cord, Egg Cell
Document Summary
Gestation - the period from conception to birth. Fertilization - insemination of an ovum by a sperm. Zygote - new cell created when the sperm and egg fuse. Placenta - the support system that, via the umbilical cord, provides food and oxygen to the developing child and carries waste products away. Implantation - on reaching the uterus, the zygote embeds in the uterus nutrient-rich lining (or endometrium) like roots of a growing plant into soil. Infertility - failure to conceive a child after 12 months of sexual intercourse without birth control. Fertility drugs - hormone-based agents that enhance ovarian activity. Artificial insemination - the most common treatment for male infertility, which involves inserting sperm directly into the woman"s uterus with a syringe. Surrogate mother - the woman who is impregnated with male"s sperm through artificial insemination or with the couple"s embryo, conceived in vitro. Gametes - sex cells, the male sperm and female ovum.
