| porcine reproductive and respiratory syndrome | <syndrome> A syndrome characterised by outbreaks of late term abortions, high numbers of stillbirths and mummified or weak newborn piglets, and respiratory disease in young unweaned and weaned pigs. It is caused by swine infertility and respiratory syndrome virus. (radostits et al., veterinary medicine, 8th ed, p1048) (12 Dec 1998) |

| assisted reproductive technology | Originally, a range of techniques for manipulating eggs and sperm in order to overcome infertility. Encompasses drug treatments to stimulate ovulation; surgical methods for removing eggs (e.g., laparoscopy and ultrasound-guided transvaginal aspiration) and for reimplanting embryos (e.g., zygot intrafallopian transfer (or ZIFT); in vitro and in vivo fertilization (e.g., artificial insemination and gamete intrafallopian transfer (or GIFT); ex utero and in utero foetal surgery; as well as laboratory regimes for freezing and screening sperm and embryos, and micromanipulating and cloning embryos. The field's first major success came in 1978 with the birth of "test-tube baby" Louise Brown, engineered by Steptoe, Edwards, et al., of England. As the technologies spread, they increasingly are being employed for purposes beyond infertility, i.e., to reduce the risk of, or avoid passing on, hereditary disease and to select for infant sex. Further uses that would aim at improving the "quality" of offspring have been widely discussed and raise profound legal and ethical questions. See: eugenics. (05 Mar 2000) |
| basic reproductive rate, ratio | <epidemiology> See Reproductive Ratio. (05 Dec 1998) |
| cells, reproductive | The eggs and sperm are the reproductive cells. Each mature reproductive cell is haploid in that it has a single set of 23 chromosomes. (12 Dec 1998) |
| reproductive | Relating to reproduction. (05 Mar 2000) |
| reproductive adaptation | A peculiarity of the reproductive mechanism of a species that results in it being better fitted to its environment (for example, prolonged seed dormancy). (09 Oct 1997) |
| reproductive assimilation | In sensorimotor theory, an active cognitive process by which past experience is applied to novel situations. (05 Mar 2000) |
| reproductive cells | The eggs and sperm are the reproductive cells. Each mature reproductive cell is haploid in that it has a single set of 23 chromosomes. (12 Dec 1998) |
| reproductive control agents | Substances used either in the prevention or facilitation of pregnancy. (12 Dec 1998) |
| reproductive cycle | The cycle which begins with conception and extends through gestation and parturition. (05 Mar 2000) |
| reproductive endocrinologist | An ob-gyn who specialises in the treatment of hormonal disorders that affect reproductive function. (09 Oct 1997) |
| reproductive history | An important aggregate factor in epidemiological studies of women's health. The concept usually includes the number and timing of pregnancies and their outcomes, the incidence of breast feeding, and may include age of menarche and menopause, regularity of menstruation, fertility, gynecological or obstetric problems, or contraceptive usage.
