Semen

Human reproduction is any form of sexual reproduction resulting in the conception of a child, typically involving sexual intercourse between a man and a woman. During sexual intercourse, the interaction between the male and female reproductive systems results in fertilization of the woman's ovum by the man's sperm, which after a gestation period is followed by childbirth. The fertilization of the ovum may nowadays be achieved by artificial insemination methods, which do not involve sexual intercourse.

Biology Reproduction Fertility

A germ cell is any biological cell that gives rise to the gametes of an organism that reproduces sexually. In many animals, the germ cells originate near the gut of an embryo and migrate to the developing gonads. There, they undergo cell division of two types, mitosis and meiosis, followed by cellular differentiation into mature gametes, either eggs or sperm. Unlike animals, plants do not have germ cells set aside in early development. Instead, germ cells can come from somatic cells in the adult (such as the floral meristem of flowering plants).

Sperm

Semen quality is a measure of the ability of semen to accomplish fertilization. Thus, it is a measure of fertility in a man. It is the sperm in the semen that are of importance, and therefore semen quality involves both sperm quantity and quality. Decreased semen quality is a major factor of male infertility.

Sperm donation is the provision (or ‘donation’) by a man (known as a sperm donor) of his sperm (known as donor sperm) for the purpose of inseminating or impregnating a woman who is not necessarily his sexual partner. The woman may be inseminated by either natural or artificial insemination methods. Sperm may be donated privately and directly to the intended recipient, or through a sperm bank or fertility clinic. The primary recipients of donor sperm are heterosexual couples suffering from male infertility, lesbian couples and single women.

When going through a sperm bank, the recipient may select donor sperm on the basis of the donor's looks, personality, academic ability, race, and many other factors. Sperm banks or clinics are subject to varying state regulations, including restrictions on donor anonymity and number of offspring, and there may be other legal protections of the rights and responsibilities of both recipient and donor. Some sperm banks, either by choice or regulation, limit the amount of information available to potential recipients; a desire to obtain more information on donors is one reason why recipients may choose to use a known donor and/or private donation.

Science of drugs including their origin, composition, pharmacokinetics,
pharmacodynamics, therapeutic use, and toxicology.

Pharmacology (from Greek φάρμακον, pharmakon, "poison" in classic Greek; "drug" in modern Greek; and -λογία, -logia "study of", "knowledge of") is the branch of medicine and biology concerned with the study of drug action, where a drug can be broadly defined as any man-made, natural, or endogenous (within the body) molecule which exerts a biochemical and/or physiological effect on the cell, tissue, organ, or organism. More specifically, it is the study of the interactions that occur between a living organism and chemicals that affect normal or abnormal biochemical function. If substances have medicinal properties, they are considered pharmaceuticals.
