The ovaries function cyclically. One of the follicles while maturing becomes dominant and prevents others from maturing. The ovum matures in the dominant follicle. When the follicle completely matures, it bursts and the egg cell moves through fallopian tubes to theuterus. The process is calledovulat...
The two cells found in the body are somatic or vegetative cells and sex or germ cells. The germ cells are responsible for forming sperm and ovum,... Learn more about this topic: Germline vs. Somatic Mutations | Definition & Differences ...
What is a Spermatozoon? A spermatozoon is the male sex cell orgametethat fertilizes the female egg orovumin organisms that reproduce sexually, including all animals and some plants. Unlike most of the cells that make up multicellular organisms, spermatozoa consist of a head and at least one fl...
Asthenozoospermia is a decrease or absence of sperm motility, making it difficult for the sperm to meet the egg for fertilization. It is a very common cause of infertility in men and is diagnosed by means of a seminogram.
The Initiation of Life The first month of pregnancy starts from the moment when an ovum (an egg) and a sperm meet in the uterine tube. During thefirst weekafter the conception, the cells in the ovum start to divide, and at the same time the egg moves to the uterine cavity. By the ...
What causes capacitation of sperm? Sperm cells are harvested through ejaculation or harvested from the caudal epididymis and allowed to liquefy at room temperature. Capacitation can then be induced byadding media designed to mimic the electrolytic composition of the fallopian tubes, where fertilization...
Artificial insemination consists of introducing a capacitated semen sample into the uterus. It is a simple process and its price is 1000$-2500$, difference due to the fertility clinic and the origin of the sperm.
"As the nuclei of the ovum and sperm unite during the first hours of fertilization, they bring together twenty-three chromosomet from the mother and twenty-three chromosomes from the father. These chromosome sets carry some 15,000 genes from each parent cell. ...
. How so? Austriaco holds that, because the two cells are organized and behave differently, it follows that their ontological identity is different, and he takes this logical-causal sequence to be identical with that contained in the axiom that agere sequitur esse. This axiom, however, states ...
"The principal functions of this (female reproductive) system are to produce an ovum, enable its fertilization and implantation, and allow growth and safe expulsion of the fetus into the external world. The menstrual cycle is critical for facilitation of the initial steps of this raison d'être...
