in the past 4 years and 5 months from January, 1959 to May, 1963, autopsy was performed on 5559 eases of endogenous sudden death in the Medical Examiner's cases. Out of that number, 34 coition deaths whose circumstances were determined, were chosen and investigation yielded the following results : 1) The preponderance of the so-called coition death occurred in males (28 cases compared with 6 females). 2) The cases occurred in the 3rd decade (9 cases), the 5th decade (8 cases), the 2 nd decade (6 cases), the 4th decade (6 cases) and the 6th decade (5 cases). However, these were not observed in teen-ager or 7th decade. 3) Speaking of the incidence by seasons, the cases occurred frequently in spring (14 cases), winter (8 cases), summer (6 cases) and fall (6 cases) in this order. 4) As for causes of death, more deaths in males were from cardiac causes (18 cases), whereas they were from cerebral hemorrhage in females (4 cases). 5) Deaths occurred frequently in hotels (18 cases), followed by homes (11 cases), sweethearts' houses (3 cases) and other places (2 cases). 6) Coition deaths occurred most often in relations with lovers (16 cases), followed by wives (7 cases), waitresses (3 cases), prostitutes (2 cases), common-law wives (2 cases) and mistresses (1 cases). Sudden death after masturbation occurred in 3 cases. 7) Concerning ' age differences, males who died were older by 20 on the average, while males were 3 years older than females who died. On the total average, the males were 13 years older. 8) Prior to sexual intercourse, a drunken state was noticed in 12 cases. 9) In regard to the time between copula. tion (including masturbation) and death, sudden deaths occurred most frequently during intercourse (11 cases), less frequently upon intercourse (8 cases), 30 minutes after intercourse (4 cases) and one hour after intercourse (4 cases). Death occurred in the remaining 7 cases 18 hours after copulation. 10) Potential basic diseases consisted of aneurysm of the brain, atherosclerosis, heart hypertrophy, syphilis, etc. 11) So-called coition deaths accounted for 0.6% of endogenous sudden deaths. 12) These coition deaths are generally resultant from potential basic diseases loaded with the physiological excitation and consumption of sexual intercourse. Drinking and other changes in the en. vironment enhance mental excitation with a result of more remakably increased physiological excitation. These seem to play an important role in the formation of a state leading to coition death
