Smoking affects fertility – in many different ways

By | April 10th, 2015|

You may have heard from many sources that you should quit smoking if you’re trying to conceive. Is there any scientific background behind this claim and how does tobacco affect fertility? Dozens of studies have been published exploring the effect of tobacco on sperm quality, male and female fertility. This amount of data allows us to get a good insight in how smoking can affect our ability to conceive and whether this effect is limited only to men. What do cigarettes contain? Once a cigarette is lit, it generates over 4000 compounds through complex chemical processes. The major substances that [...]

Fruit and vegetables high in pesticides can lower sperm quality

By | March 23rd, 2015|

Two interesting studies have appeared last year, both examining the effect fruit and vegetables have on sperm quality. The first study was performed in the Massachusetts General Hospital between April 2007 and June 2012. This study examined how high intake of fruit and vegetables affects sperm quality. Over 150 men were questioned about how often they eat different kinds of food and the fruits and vegetables present in their nutrition were classified according to their pesticide residue levels. After each participant’s pesticide residue level was calculated, the researchers came to some interesting discoveries. The total intake of fruit and vegetables [...]

Optimal nutrition for fertility and longevity

By | March 16th, 2015|

For decades scientists believed that animals need to make a sacrifice in order to reproduce – they can either choose fertility and to have offspring, or they could have a long and happy life. Not an easy choice, is it? However, a new study that was done in Australia suggests otherwise. The article published in the Proceedings of the National Academy of Sciences of the USA claims that it could be possible that mammals live longer and increase their fertility by simply manipulating their nutrition. Researchers have been observing over 800 mice that were on diets with varying amounts of [...]

Impact of physical labour, meds and hypertension on fertility

By | March 13th, 2015|

More and more researchers are directing their attention towards exploring different factors that may be affecting both male and female fertility. One area that hasn’t been investigated until recently is a relationship between strenuous work, with health and semen parameters in men who are trying to conceive. One such study was published a few days ago on the Fertility and Sterility website. The study was done at the National Institute of Health and at Stanford University in California. The scientists followed 456 men with the average age of 31.8 years, where more than half of the participants didn't have children [...]

Obesity may be affecting your TTC efforts

By | March 9th, 2015|

In the past few decades, male obesity has nearly tripled. This data is correlated with an increase in male infertility – and may be the very cause of it. There is more and more evidence appearing suggesting that obesity has a negative impact on male reproductive potential. Not only does excess weight influencessperm parameters, but it can also cause a decrease in libido and erectile dysfunction, making the process of trying to conceive much more difficult. Several studies have shown that if a male partner is obese and a female has a normal BMI (body mass index); or if both [...]

Caffeine – how much is too much?

By | March 6th, 2015|

As a society, we are almost addicted to caffeine. We drink it in the morning expecting it to help wake us up, in the afternoon to boost our energy levels, on the way home from work or after a workout. It lurks from our lattes, teacups and energy drinks. That is why it is so easy to start drinking too much caffeine without being aware of it. A study done in Portugal shows that a cup of coffee a day shouldn’t affect male fertility seriously, but greater amounts of caffeine may do so. This study found that heavy consumers of [...]

Are phytoestrogens really affecting male fertility?

By | February 27th, 2015|

Phytoestrogens are substances found in plants that serve as a line of defense and they have a role in cell-to-cell communication. Phytoestrogens can be found in soybeans, flax seeds, sesame seeds, oats, barley, etc. These compounds gained attention in the public arena due to their ability to imitate the effect of oestrogen once ingested by humans. Studies show a connection between phytoestrogens and female fertility, proving that these substances have a significant negative impact on female reproductive health. But what effect, if any, do they have on male reproduction? The first insights into the effects of phytoestrogens on fertility showed up in [...]
