“…This pubertal criterion can be considered as the counterpart of the menarche in girls (Carlier & Steeno, 1985). Different names are used for the first ejaculation – oigarche (Carlier & Steeno, 1985; Janssen, 2007), spermarche (Hirsch et al. , 1985).…”

Timing of pubertal maturation according to the age at first conscious ejaculation

et al. 2011

The first conscious ejaculation (ejacularche) is an important event in the somatic and psychic development of boys. The aim of this study was to reveal the age at first ejaculation in Bulgarian boys and to observe the secular trend of this marker for puberty. A total of 1582 (901 from urban and 681 from rural origin respectively) gave a positive answer admitting the age in years at the first ejaculation. The mean age ± standard deviation (SD) of ejacularche was 13.27 ± 1.08 years, and the median was 13.0. It was found a significant difference between the urban (13.34 ± 1.07) and rural (13.18 ± 1.08) inhabitants in relation to the age of their remembered first ejaculation (P = 0.003). A secular trend in appearance of ejacularche was revealed when our results were compared with those from the previous studies in Bulgaria. We can suggest that in the presence of testicular volume ≥6 ml asking about ejaculation is reasonable and not superfluous. Self-reported spontaneous ejaculation can be used as an index of male pubertal timing.

“…Furthermore, their semen, if any, is not yet capable of fertilization [Janczewski & Bablok 1985]. This is also the typical age at which the testes start to enlarge and pubic hair appears [Tanner 1962], and at which boys experience their first ejaculation and orgasm [Janssen 2007]. …”

The pattern of facial preferences in boys at early adolescence

Research on facial attractiveness has become very popular in past few decades and the psychoevolutionary perspective has recently gained a good measure of scientific currency. This perspective assumes that many of the criteria for facial preferences have been molded by natural selection so that the pursuit of and contact with individuals perceived as attractive is beneficial for one's reproductive success [Symons 1995, Gangestad & Scheyd 2005, Rhodes 2006]. It is no wonder then that facial preferences are, to a great extent, universal [Langlois et al. 2000]. Facial attractiveness is a reliable signal of possession of good genes, good health and desirable personality, and physically attractive people enjoy, on average, more popularity, and have better reproductive success than less attractive ones (see review by Kościński [2008]). Although attractiveness perception in adults has been extensively studied, the development of facial preferences in childhood and adolescence remains poorly represented. ABSTRACT Despite numerous studies on perception of facial attractiveness in adults, preferences in adolescents remain poorly characterized. The aim of present study was to explore facial preferences in boys at early adolescence (11-13 years old) and compare them with preferences of men. All males evaluated the same 30 female faces, which were also assessed by independent judges for several perceived features. Regardless of age, boys assessed attractiveness much the same as men, and the strengths of their preferences for specific facial features were similar to those of men. The pubertal maturity (calculated on the basis of the presence of pubic hair at two sessions spaced ten months apart) correlated positively with strength of preference for several facial features (specifically: maturity, sexiness, marital appearance and friendly appearance). This remained true even after controlling for age and psychosexual development, suggesting that sex hormones are involved in the development of facial preferences in pubescent boys.

“…Several studies on China, Denmark, France, Hungarian, and Copenhagen present growth chart of body size, age at spermarche, and urinary excretion of spermatozoa. However, none of these studies showed the relationship between age at spermarche and body size (Schaefer et al 1990;Pedersen et al 1993;Yan et al 1999;Rochebrochard 2000;Ji 2001;Bodzsar & Zsakai 2007;Janssen 2007;Zhu et al 2009). On the other hand in Sragen (center of Java) peak height velocity of the boys is reported to reach at the same time as their age at spermarche; however, their peak weight velocity reached before that (Suratno 2009).…”

Gonad maturation in pubertal girls and boys is accompanied with somatic growth spurt, changes in quantity and distribution of body fat (BF), development of secondary sex characters, and relevant physiological events. Menarche (first event of menstruation) and spermarche (first event of nocturnal sperm emission) are usually used as indicators of gonad maturation. We found that median age at menarche of Arfak girls in Manokwari, West Papua is 12.2 years, while median age at spermarche of boys is 13.6 years. A possible factor causing young age at menarche is due to adaptation to unstable environmental conditions because of high risk of mortality by malaria disease during childhood. The events of menarche and spermarche achieved one year after the peak body height (BH) velocity, and just before or at the same time with the time of maximum growth rate of body weight (BW), body mass index (BMI), and BF. The average BMI of Arfak girls was big at 21.9 kg/m 2 at the time of their menarche. Bigger average BMI might be caused by prepubertal slowing down of BH growth compare to growth of BW whichis still increasing. Girls accumulate BF before puberty to be used as an energy reserve for the occurrence of menarche. At the time of development of secondary sexual characters girls use the fat reserve so it decline sharply after puberty. In boys, growth rate of BF was stopped at 11 years old, and then growing negatively presumably because boys use fat mass for the occurence of spemarche. BF growth rate reached the lowest point at the age 16 years old, and then increase linearly with age through adolescence until adulthood at age 23 years old.
