For triathletes who’ve spent years specializing in attaining athletic targets, shifting focus to a brand new aim, like having a child, could be a bit jarring. That’s much more true if the athlete in query doesn’t discover themselves within the household means immediately. In any case, triathletes are used to a easy system: get a coaching plan, comply with it to the letter, and execute on race day. Relating to getting pregnant, nonetheless, the best “plan” to comply with isn’t at all times apparent. (Effectively, OK, perhaps some components are apparent…)
A fast search of “fertility” on triathlon web sites and in social media teams will deliver up loads of anecdotes about how modifications to an athlete’s coaching impacted, negatively or positively, their means to conceive. Usually, these tales are introduced as proof that altering a motorbike seat, reaching a selected physique fats share, or sticking to a sure variety of coaching hours is the reply to changing into a mother or dad.
However in precise truth, understanding how your coaching is perhaps affecting your fertility is a bit more sophisticated. So we went to Dr. Diana Vaamonde, co-editor of Fertility, Pregnancy, and Wellness in addition to Exercise and Human Reproduction, in addition to a co-author of quite a few research on the affect of train on male fertility, to seek out out what widespread beliefs are myths, which of them are based mostly in info, and, most significantly, what triathletes who need to begin a household can do to enhance their fertility.
Does biking have an effect on sperm rely?
Biking, particularly, has gotten a foul rap with regards to male fertility. However what does the science say? Does biking lower sperm rely, or in any other case lower fertility in male triathletes who spend hours in aero?
“Whereas sperm rely is considerably affected, different parameters associated to semen high quality are extra affected,” Vaamonde stated. Sperm morphology (the scale and form of sperm) particularly has been found to correlate to excessive biking quantity, she stated — and that’s essential because it’s an element that’s thought of within the analysis of male fertility. She additionally notes that sperm DNA fragmentation, which refers to irregular genetic materials throughout the sperm and may also result in bother conceiving, has been proven to be a difficulty.
However why? There are a couple of potential causes, Vaamonde stated. A motorcycle seat is a possible trigger on account of friction, which, she stated, “may even additionally result in erectile dysfunction and ejaculatory alterations in some instances due to altered blood move or nerve injury.” Nevertheless, this isn’t as widespread as is usually believed: A 2018 study led by Mohannad Awad on the College of California-San Francisco discovered that although cyclists had statistically increased odds of urethral stricture, or narrowing of the urethra, when in comparison with swimmers and runners, their sexual or urinary capabilities had been no worse.
Nevertheless, different areas of reproductive operate is perhaps affected by coaching. Analysis suggests the calls for of train on the physique have some impact on intercourse hormones and the steadiness of free radicals and antioxidants within the physique, which might have an effect on fertility. Vaamonde stated that these results embrace:
- The alteration of sex steroid hormones in endurance athletes. “That, by itself, will have an effect on sperm parameters,” she stated. That issues as a result of intercourse steroid hormones modulate reproductive operate, and modifications to androgen (like testosterone) ranges can have an effect on fertility.
- Exhaustive endurance train may also have a detrimental effect on the gonadal axis, the mind’s switchboard between the hypothalamus, the pituitary gland, and the gonads.
- Power imbalance, which might happen after we prepare with out correct fueling and restoration. When this occurs, free radicals run rampant within the physique, inflicting a state referred to as oxidative stress which might injury cells—together with these affecting reproductive operate.
- Thermal stress (or extreme warmth) can also be a difficulty, Vaamonde stated: “A rise in warmth might negatively have an effect on sperm within the testes and epididymis.” Warmth stress to the testicles—from ambient temperatures, elevated core temperature whereas exercising, and/or constricting clothes or environments—may affect sperm rely, motility, and even the sperm’s genetic materials. In any case, the testes are positioned outdoors the physique cavity for good purpose: the sperm manufacturing course of requires temperatures decrease than the physique.
- “Some researchers have reported elevated prevalence of significant types of varicocele [which is an enlargement of the veins that transport oxygen-depleted blood away from the testicle] in athletes, and likewise that sports activities observe appears to worsen the situation.” In extreme instances, varicocele can enhance scrotal temperature and have an effect on sperm manufacturing and high quality.
Relating to males who train, although, you want to understand that their coaching shouldn’t be the one potential purpose for infertility or subfertility. In any case, nearly 1 in 7 couples will experience infertility, they usually definitely aren’t all coaching for a triathlon, so in the event you and your associate have given it the previous faculty attempt to nonetheless haven’t gotten pregnant, speaking to a fertility specialist about different potential causes could also be a clever transfer.
Coaching and feminine fertility
One factor to remember is that no two our bodies are precisely alike, and what labored on your coaching buddy when she was attempting to get pregnant may not give you the results you want—and that doesn’t imply something is improper with you.
There are quite a lot of elements concerned in feminine fertility, however with regard to how sport impacts it, Vaamonde stated that the very first thing to think about is whether or not your cycle is common. “Any ovulatory disturbances can be of concern,” she stated. These disturbances might or might not be associated to your coaching—some ladies have pre-existing circumstances that could be affecting their fertility absent of your coaching load.
Even in the event you menstruate recurrently, it’s additionally potential to have anovulatory cycles, that are cycles the place you don’t launch an egg from the ovaries. A number of elements may cause anovulatory cycles, like hormonal imbalances on account of hormonal contraception, exercising excessively, experiencing vital stress, or being under- or obese. The tough factor is, Vaamonde stated, “some ladies will not be even conscious, as there could also be a bleeding that they mistakenly take for an actual menstrual bleeding.” That’s an actual drawback for girls attempting to conceive. “If there isn’t a ovulation, there can’t be fertilization and thus no being pregnant,” Vaamonde stated. And so, even in case you are seeing proof of a daily cycle, she stated it’s nonetheless acceptable to examine your hormone ranges and ovulation in case you are having bother conceiving.

Vaamonde additionally means that feminine athletes pay shut consideration to their total well being and wellbeing, for the reason that female athlete triad of power deficiency, amenorrhea (absent or irregular durations), and osteoporosis is a priority. These elements might affect your means to conceive, however has well being implications properly past any potential being pregnant, too.
Fertility in females shouldn’t be solely a matter of power availability— right here’s a mind part, too. In keeping with a 2012 research by researchers at Boston College Faculty of Public Well being, extremely vigorous train, achieved on the common, can disrupt the information received by the corpus luteum (the a part of the follicle that is still after ovulation). For the reason that corpus luteum produces progesterone, which is critical for being pregnant, that may thwart your efforts.
And that’s not all. A 2022 study on female endurance athletes discovered that, when in comparison with non-athletic ladies, they’d increased ranges of androgens and corticosteroids—each of which might negatively affect the power to conceive.
However, actual discuss. Should you’re having bother getting pregnant, how possible is it, actually, that your train habits are responsible?
Round 10% of girls take care of some kind of infertility, and their danger will increase with age. However, whereas low physique fats on account of extreme train and being underweight are listed as widespread causes of feminine infertility by the Cleveland Clinic, they’re removed from the solely widespread causes. In any case, loads of lean, lively ladies conceive with none bother.
Researchers on the Norwegian College of Science and Know-how looked into differences in fertility between women who trained almost every day and women who trained until exhaustion, based mostly on info initially gathered about their bodily exercise and follow-up information on being pregnant and childbirth gathered a decade later. They discovered that 11% of the near-daily exercisers reported fertility issues, and a whopping 24% of those that exercised to close exhaustion did as properly. That relationship between train and fertility was even clearer with ladies beneath 30, since age is so carefully tied to fertility in ladies.
And the age issue is especially noteworthy right here, since ladies having fun with success of their athletic prime may additionally be extra more likely to postpone beginning a household till later of their triathlon profession, and since female fertility decreases significantly by the age of 35 (and much more so at 40) an individual’s bother conceiving could also be tied to age, not exercise.
What you are able to do to extend the percentages of conception
All of this would possibly sound intimidating, however don’t put your bike out to pasture simply but. There are issues you are able to do to up your probabilities with out hanging up your equipment.
However first, you want to take inventory of the place you land within the realm of triathlon coaching. Vaamonde stated that it’s essential to differentiate between leisure, beginner, {and professional} athletes. There are more likely to be vital variations between their coaching hundreds and life, and people variations, as we’ve now seen, can affect fertility in males. A 2012 Boston University study discovered this to be typically true for girls, too; lean ladies who decreased their train from vigorous to reasonable improved their fertility. Nevertheless, for obese or overweight ladies, the findings recommended that any sort of bodily exercise, even when it was vigorous, could possibly be useful to their fertility.
So, what does that basically imply?
“To scale back the chance of infertility/subfertility, holding coaching load at a wholesome degree can be a should,” Vaamonde stated. A “wholesome degree” is completely different from one athlete to the subsequent, however usually, your coaching must be in steadiness together with your restoration. Lots of the signs of overtraining, the Female Athlete Triad/Male Athlete Triad, and low energy availability overlap to point an imbalance between coaching and restoration, and coaching must be scaled again. These signs embrace:
- Hassle sleeping
- Diminished intercourse drive
- Lack of urge for food
- Temper modifications
- Decreased motivation
- Frequent accidents
After all, with regards to skilled athletes, she acknowledges that this may increasingly not at all times be an possibility. In any case, coaching to win is their job, and it’s one factor for a feminine professional to reduce whereas pregnant and postpartum, however doing so previous to conception could also be a tough promote.
Nonetheless, there are essential steps athletes can take. “I might suggest that if fertility is their concern, they contact a fertility specialist and examine their fertility,” she stated. Getting a baseline in your fertility and persevering with to examine it with an expert is essential, in line with Vaamonde, as a result of many athletes start coaching at a younger age — usually, in prepubescent years — and that may make it exhausting to see the connection between train and any reproductive disturbances. “Performing common reproductive checks might assist the individual assess their reproductive potential and whether or not or not that is being altered, so early screening is paramount,” Vaamonde stated. Relating to testing your fertility, there are a variety of options. Girls can get their anti-Mullerian hormone (AMH) ranges examined at their physician’s workplace, lab, or with an at-home equipment, whereas blood exams can measure ranges of follicle-stimulating hormone (FSH). Different exams, starting from blood and urine exams, x-rays of the uterus and fallopian tubes, and, for males, a semen pattern, may additionally be really helpful, however speaking to your physician about your issues and asking about out there exams is at all times a terrific place to start. She or he might then refer you to different specialists if wanted.
Whether or not you’re an expert, a beginner, or someplace in between, Vaamonde believes having power availability that matches power expenditure could also be an acceptable technique, particularly for feminine athletes who’re experiencing irregular or absent cycles.

And dietary supplements could possibly be an possibility in some instances, she stated. “Oxidative stress, aka the imbalance between free radicals, and most significantly reactive oxygen species, and antioxidants, will be suspected. Due to this fact correct antioxidant supplementation may additionally assist,” Vaamonde stated. Compounds like vitamin C, resveratrol, N-acetylscysteine, and Coenzyme Q10 are good examples. However that may be a difficulty for professionals, as she notes some compounds might intrude with efficiency or present up in a doping screening; each the compound and the dosage could be a issue right here.
Steps to take
The underside line is, in the event you’re involved about your fertility, there are a couple of steps you’ll be able to take to spice up your odds of constructing a child:
It’s additionally essential to notice that you just don’t should determine this out your self. Mentioned Vaamonde: “These assessments require a very good understanding and dealing between professionals, ideally in multidisciplinary groups—sport coaches, nutritionists, OB GYN physicians, and andrologists.”
