Ice-cold water drink for the long run,
Additionally, some research has shown that actually icing your testicles regularly can counteract previously heat-damaged sperm and can improve function. Icing the area for 30-60 minutes a day for a few months may increase sperm count by up to approximately 100%.
According to the study, drinking one cold drink per day was associated with 25 percent reduced fertility in women and 33 percent lower fertility in men.
FOOD FOR THOUGHT: Couples trying to conceive should increase their intake of 'warm' ingredients, such as yams, sweet potatoes and chestnuts, Wang Ya-hsiu said. Consumption of cold drinks can lead to infertility in not only women, but also men, a Taichung-based doctor of traditional Chinese medicine said on Monday.
For men, dehydration can lead to decreased sperm quality and less volume of semen. For women, dehydration results in poor egg health, and less cervical mucus secretion which is vital for transportation of sperm to the fallopian tubes.
There is no specific frequency with which a man should ejaculate. There is no solid evidence that failure to ejaculate causes health problems. However, ejaculating frequently can reduce the man's risk of getting prostate cancer. Ejacu-lation can be through having sex or masturbating a few times a day.
Best positions: deep penetrative sex is preferable. This helps to deposit the semen and sperm closest to the woman's cervix so they are given the best opportunity to get to the egg in the fallopian tube. Twelve hours before ovulation is thought to maximise the chances of conceiving with a boy.
Boost fertility
Although there isn't a wide range of research, some small studies have found that there is evidence that suggests that cold showers can increase male fertility. Hot baths have shown to reduce the level of sperm count, and cold showers are a good counter activity to reverse the effects.
No scientific proof exists that Mountain Dew — or any other soda, for that matter — has any effect on sperm count. These rumors have been around for years. Many people have heard this urban legend, but Mountain Dew cannot be used as some kind of male birth control.
Should you have cold water or cold drinks during pregnancy? It is absolutely safe. Pregnancy is an extension of the physiological body and not any sickness. So, all that your body was used to or capable of doing before the pregnancy, can be done during pregnancy too.
Women who drink large amounts of alcohol (seven or more drinks a week or more than three drinks on one occasion) are more likely to have heavy or irregular periods and fertility problems. Alcohol can also affect ovulation, which can make it difficult to conceive.
If temperature goes upto 40° C the sperms will start to die and at the temperature of 42° C -- all sperms will be dead.
Ideally, sperm production occurs at around 93.2ºF (34ºC). This is 5.4ºF (3ºC) below normal body temperature of 98.6ºF (37ºC ). But your testicles can get too cold for good sperm production, too. Cold temperatures cause the scrotum and testicles to retreat up toward the body.
Simply taking fewer hot showers boosts your sperm count and quality, since heat, in general, affects sperm production. There's no research to show that there's any equivalent relationship of cold water exposure or hot water reduction with female fertility. The research only points to male fertility.
A cold shower might invigorate, improve blood circulation, give a glowing skin but it does not boost testosterone levels. If it is a hot day or you had a vigorous workout, a cold shower will soothe sore muscles, cool down body temperature, including the testicles which is good for sperm quality.
Nature is designed to favour the conception of boys from September to November and girls from March to May because of an evolutionary mechanism aimed at keeping the overall sex ratio as near to 50:50 as possible, the scientists said.
They found that the most fertile months for conceiving a boy were from September to November, while the lowest fertile period was from March to May.
My general response is that it's a 50/50 chance that a woman will have a boy or a girl. But that's not exactly true – there's actually a slight bias toward male births. The ratio of male to female births, called the sex ratio, is about 105 to 100, according to the World Health Organization (WHO).
Use of cocaine or marijuana may temporarily reduce the number and quality of your sperm as well. Alcohol use. Drinking alcohol can lower testosterone levels, cause erectile dysfunction and decrease sperm production. Liver disease caused by excessive drinking also may lead to fertility problems.
These associations were primarily explained by intake of low-fat milk. The corresponding results for low-fat milk were 30% (95%CI 1,51) higher sperm concentration and 8.7 (95%CI 3.0, 14.4) percentage units higher sperm motility. Cheese intake was associated with lower sperm concentration among ever smokers.
