“…Several studies have been conducted to identify seasonal effects on semen parameters (Andolz, Bielsa, & Andolz, 2001;De Giorgi et al, 2015;Levine et al, 1988;Levitas et al, 2013;Ombelet et al, 1996;Santi et al, 2018;Zhang et al, 2013). In the current…”

“…The seasonal factors affecting human birth rates may be related to semen parameters. Several investigators have reported seasonal variations in semen parameters, especially in the temperate climate zone, where seasonal temperature differences are evident (Levine et al, 1988;Levitas, Lunenfeld, Weisz, Friger, & Har-Vardi, 2013;Santi et al, 2018;Zhang et al, 2013). However, the reports are controversial.…”

Natural life depends on biological rhythms that enable living creatures to thrive and survive. Biological rhythms or clocks allow species to adapt their physiological functions to external environmental changes. The environmental changes, creating a complex circadian (day) and circannual (year) rhythmicity, affect the whole organism, particularly the endocrine glands and the gonads. The hypothalamic-pituitary-gonadal axis is extremely susceptible to circannual rhythmicity, regulating the hormone levels (Santi et al., 2020). One of the most critical functions of annual hormone changes in nature is the optimisation of reproduction timing, thereby ensuring the highest survival chances of the offspring (Henkel et al., 2006; Roenneberg & Aschoff, 1990). Unlike other animal species, humans do not necessitate to set a season of fertility and can reproduce throughout the entire year. Although the human is not normally considered a seasonal breeder, many reports demonstrated the seasonal changes in gonadotropins, gonadal hormones and melatonin

“…In comparison between means of sperm count according to season, there were significant differences between means among winter, summer and post monsoon with respect to monsoon (Table 9). Saint Pol et al 64 and Levine et al 63 reported a significant seasonal variation in sperm count, with the highest sperm counts observed in late winter and early spring and the lowest in late summer. Henkel et al 69 in their study demonstrated seasonal changes in Neutral Alpha Glucosidase which is correlated with sperm concentration.…”

Introduction: World over studies are being done by different group of workers to understand the time of deliveries conducted. Surprisingly majority of deliveries were following a pattern, seasonally. Today in this busy world, couples choose comparatively a free time for delivery and preparation for conception is done accordingly. Apart from these, it is clearly shown majority of deliveries are conducted during a particular season. We hypothesised that the change in semen quality during different seasons is responsible for this phenomenon. Materials and methods: Present study conducted on semen quality included 12,408 semen samples collected from different laboratories of Bangalore city during 8 years (2000–2007) period of time and were analysed season wise. Results: Results showed sperm concentration was significantly lower in monsoon than in winter season. Humidity and pressure influenced sperm count. Forward moving sperms were influenced by temperature and pressure. Summary: The study concludes the change in birth rates seen during different season in a year is due to the quality of semen responsible for conception.
