The production of gametes is a biological process occurring in organisms that sexually reproduce. Females make gametes called eggs, and males make gametes called sperm. Both egg and sperm cells begin as identical germ cells and are produced through a process of cell division called meiosis, which reduces the number of chromosomes in the germ cell from 46 (diploid) to 23 (haploid). In human males, meiosis begins after birth, and, upon reaching puberty, men produce sperm continuously for the rest of their lives. In human females, meiosis begins before birth and the raw materials for egg cell production are formed …

Atrophy of the left or right side of the hippocampus has been related to cognitive deficits and psychiatric disease. In this study, we examined the correlation between the hippocampal volume laterality index and the relative lengths of the second (index finger) and fourth (ring finger) digits (2D:4D) in healthy female subjects. The 2D:4D ratio is fixed in utero, and the ratio is higher in women than in men. There is evidence that this ratio is an indicator of the intrauterine concentration of testosterone, which influences the development of different regions of the brain. Assessing the volume of different parts of …

Patients remanded over a two-year period to Woodbridge Hospital by Court Order were studied retrospectively. Schizophrenia was the most common diagnosis, theft and robbery the most prevalent offences. Males greatly outnumbered females. There were important gender differences, with males tending to commit sexual offences and females, theft and mischief. Males were less likely to be acquainted with their victims but those who caused hurt were more likely to know their victims. Outrage of modesty and theft were more likely to be committed against strangers. The reconviction rate was 26%, with repeat offenders more likely to commit sexual offences and theft. …
