“…In contrast, for the female, it may be associated with a reduced fecundity (45). Underweight men or women who exercise vigorously may be at an increased risk of being subfertile (46,47). In this study, the percentage of women and men that practiced sport more than 4 h/wk was 11.90% and 12.70%, respectively.…”

IntroductionCurrent evidence indicates a 9% prevalence of infertility (1). Patients that are hoping to get pregnant might wonder about their fertility and whether they can improve it. There is an increasing body of evidence that lifestyle factors can influence reproductive health. The post-industrial era is associated with an excessive exposure to certain lifestyle factors and behaviors that have the potential for a positive or negative effect on reproductive performance (2). Some factors might be beyond patients' control, such as medical issues that affect both male and female fertility, but other lifestyle factors, such as nutrition, weight, exercise, psychological stress, and age of starting a family can be modifiable (2).Negative effects of lifestyle factors such as environmental and occupation exposure, illicit drug use, cigarette smoking, medications, weight management, exercise, alcohol and caffeine consumption are well documented (3-6). Lifestyle-related fertility disorders were estimated to be responsible for 5% of all cases of subfertility (7). To enhance fertility, such lifestyle factors, once identified, can be modified.The findings of the effect of body weight on fertility are firmly established in both sexes. Pathophysiologically, being over or underweight would lead to hormonal changes that would lead to oligomenorrhea and anovulation with subsequent subfertility (8-14). Studies investigating sporting behavior indicate that excessive sport, in terms of frequency, duration and intensity have a negative effect on hormone balance and reproductive performance. The findings of these studies were independent of the confounding factors of age, smoking or body mass index (BMI) (15)(16)(17)(18)(19).There is a plethora of studies that document the detrimental effect of smoking on both male (20,21) and female reproductive performance (22,23). Research indicates that smoking impairs sperm count, motility, morphology and fertilization capacity (20). Women smokers have a significantly smaller number of pregnancies and a higher incidence of miscarriages and ectopic pregnancies (23).Commonly encountered drugs and medications may be detrimental to semen parameters and male sexual performance (24). These agents may exert a gonadotoxic effect on the testicles, alter the hypothalamic-pituitary-gonadal axis, and impair ejaculation, erectile function and libido (25).Recreational drugs can affect male fertility. The long- AbstractObjectives: To explore the prevalence rates of lifestyle practices linked to fertility disorders. Materials and Methods: A cross-sectional descriptive study, using a validated questionnaire, was conducted among sub-fertile couples attending the fertility center at Jordan University of Science and Technology between February 2013 and August 2014. Results: A total of 126 couples took part in the study. The average length of sub-fertility was 4.2 years. The mean age of the women was 31 years, of whom 70% were <35 years of age. Over 6% engaged in regular sporting activity. Less than 1% of women smo...

“…Low testosterone levels could cause the development of hypogonadotropic hypogonadism characteristics, and oligo-spermatogenesis [23], and in this sense long-term strenuous exercise could have a deleterious effect on reproduction [24]. Moreover, a positive relationship between strenuous bicycle riding and erectile dysfunction has been reported; the underlying causative pathophysiological mech- anism has been linked with chronic perineal vascular trauma, rather than a direct association with training volume or energy deficit [25].…”

A b s t r a c t Background. A growing body of research has investigated the potential health risks of excessive exercise on human health. There is now a clear need for an up-to-date, critical synthesis of reliable findings on this topic. Objective. To determine the potential adverse biological effects of excessive exercise and overtraining among -initially -healthy men and women. Design. Brief review. Material and method. In order to identify relevant studies, the electronic database Medline was searched using the following terms/key words: "excessive exercise" OR "overtraining" AND "adverse effects". Studies had to: a) be written in English, b) published from January 1980-March 2014, and c) involve healthy men and women (individuals with no pre-existing medical conditions). Results and discussion. The main adverse effects associated with excessive exercise and overtraining among healthy individuals were musculoskeletal injuries, adverse cardiovascular effects, exercise-induced muscle damage, exerciserelated alterations of immunity, exercise-related reproductive dysfunction, chronic negative energy balance, osteoporosis, and sleep disorders. Conclusions. The findings of the present study suggest that excessive exercise and overtraining can have serious health consequences. Sports physicians, trainers and health educators should be aware of these risks and advise the people accordingly. Further research needs to be carried out in this area, including high quality trials.

“…(Adatközlőink között nem fordult elő mértéktelenül alkoholizáló/dohányzó nő.) A korábban említett hazai és nemzetközi kutatási eredmények ugyanis azt hangsúlyozzák, hogy a mértéktelen alkoholfogyasztás [28,29] és dohányzás [30,31] negatívan, míg a kontrollált mozgás vagy sport [17,21,23], valamint a mérsékelt vitamin- [19] és étrendkiegészítő- [20] fogyasztás pozitívan befolyásolja a fertilitást [8,22].…”

Bevezetés: Hazánk termékeny népességének 10-15%-a reprodukciós problémával küzd. Irodalmi adatok bizonyítják, hogy az egyén pszichés jólléte, valamint életmódja szerepet játszik a termékenységgel szorosan összefüggő általános egészségi állapot alakulásában. Célkitűzés: A vizsgálat célja a pszichés jóllét és az életmódtényezők termékenységgel való összefüggéseinek elemzése magyar mintán. Módszer: A vizsgálatban 194 nő (115 meddő és 79 termékeny) vett részt. A pszichés jóllétet standardizált, validált, önkitöltős kérdőívekkel, az életmódtényezőket saját összeállítású kérdésekkel mértük. Eredmények: A meddő nők fi atalabbak (33,98±4,89 vs. 36,43±5,81, p<0,005), és pszichés jól-létük szignifi kánsan rosszabb, mint a termékenyeké. Magasabb a depressziós tüneteik száma (BDI 14,00±12,21 vs. 7,79±9,17, p<0,005) és jobban szoronganak 53±10,56 vs. 40,25±10,65, p<0,005), mint a terméke-nyek. Az életmódtényezőket vizsgálva azt találtuk, hogy a meddő nők kevesebb folyadékot fogyasztanak (1,71±0,67 vs. 1,95±0,68, p<0,05) és közülük többen tartanak valamilyen diétát (31,30% vs. 18,42%, p<0,05), mint a terméke-nyek. A mintában a nagyobb mennyiségű folyadékfogyasztás a testtömegindextől és az életkortól függetlenül is előre jelezte annak valószínűségét, hogy egy nő a termékeny csoportba tartozzon (OR = 1,65, CI = 2,58-1,06). Követ-keztetések: Az eredmények egybecsengenek a nemzetközi kutatási eredményekkel, miszerint a reprodukciós problémával szembesülők rosszabb pszichés állapotban vannak termékeny társaikhoz képest. A szerzők az eredményeik utánkövetését, valamint a folyadékfogyasztás termékenységgel való összefüggésének további elemzését feltétlenül indokoltnak tartják Orv. Hetil., 2015, 156(12), 483-492. Kulcsszavak: meddőség, depresszió, szorongás, életmódtényezők Relationships between psychological well-being, lifestyle factors and fertilityIntroduction: 10 to 15% of the Hungarian fertile age population struggles with reproductivity problems. Previous researches have shown that psychological well-being and lifestyle factors play a pivotal role in overall health status, which is closely related to fertility. Aim: The aim of the study was to examine fertility-related psychological and lifestyle factors in a Hungarian sample. Method: 194 women (115 infertile and 79 fertile) took part in the study. Standardized, validated questionnaires were used for the assessment of psychological factors and self-administered questions were used for exploring lifestyle factors. Results: The results show that infertile women are younger (33.98±4.89 vs. 36.43±5.81 years, p<0.005) and their psychological status is signifi cantly worse compared to their fertile counterparts. The number of their depressive (BDI 14.00±12.21 vs. 7.79±9.17, p<0.005) and anxiety symptoms is higher p<0.005) compared to fertile women. Findings related to lifestyle factors show that lower level of fl uid consumption (1.71±0.67 vs. 1.95±0.68, p<0.05) and diet (31.30% vs. 18.42%, p<0.05) is signifi cantly related to infertility. In this sample higher level of fl uid c...
