1898 Marysville (Ohio) Tribune 23 Mar. 3/3 Parents may infallibly control the sex of offspring... Universally it is conceded that if the great embryologist has really discovered the secret of sex control, he has made a marvellous step forward in science.

1912 W. E. Castle in W. E. Castle et al. Heredity & Eugenics iv. 79 Negative as are the results of our study of sex control, they are perhaps not wholly without practical value.

1957 Sci. News Let. 72 253/1 Using a method of sex control based upon electrical properties of the sperm cells, Dr. Gordon was able to separate ‘male’ or Y chromosome carrying sperm cells.

2003 Population & Devel. Rev. 29 758/1 [There are] two aspects of sex control—it is control of sex, and it is a form of control of offspring.

2. Zoology. Sex determination, esp. in an animal that can change sex during the life cycle or in response to environmental conditions. Also: regulation of sexual development in an animal species that varies between sexual and asexual forms.

1911 Trans. Amer. Microsc. Soc. 30 228 For a long time the question of sex-determination,—of male as against female, and of sex-control,—of sexuality as against asexuality, (which is a different problem) has perplexed the mind of man.

1946 Q. Rev. Biol. 21 135/1 The male of the honeybee is produced uniparentally by the mated queen. It is this phenomenon that forms the basis of sex control in most species of the Hymenoptera.

1986 Amer. Naturalist 128 553 The actual genetic mechanisms of sex control in hermaphroditic fishes are not known.

1999 Jrnl. Avian Biol. 30 11/1 In birds, females are the heterogametic sex so some form of chromosomal sex control mechanism is possible.
