  • The marketing mix concept is one of the core concepts of marketing theory. However, in recent years, the popular version of this concept McCarthy’s (1964) 4Ps (product, price, promotion and place) has increasingly come under attack with the result that different marketing mixes have been put forward for different marketing contexts.

  • Multiple pregnancy involves more than one embryo (fetus) in any one gestation. Two independent mechanisms may lead to multiple gestation: segmentation of a single fertile ovum (identical, monovular, or monozygotic) or fertilization of separate ova by different spermatozoa (fraternal or dizygotic) multiple pregnancy. In the development of twins (the most frequent higher-order gestation), monozygotism is constant ( 2.3–4/1000 deliveries), whereas dizygotism has certain predispositions. Dizygotic twinning is inherited as a recessive autosomal trait via the female descendants.

  • Human spermatozoa at ejaculation are incapable of in vivo fertilization and must undergo maturational change during which they acquire the ability to fertilize oocytes. This process, known as capacitation, was described more than 50 year ago by both Austin (1) and Chang (2). Capacitation is prevented in ejaculated spermatozoa by at least one factor in seminal plasma (3). Additionally, prolonged exposure to seminal plasma can inhibit the ability of spermatozoa to undergo the acrosome reaction in vitro (4) and diminish their capacity to fertilize (5).
