This 'fertile window' is once a month, generally close to the time of ovulation when the woman ovulates and releases an egg approximately 2 weeks before the next period is due. Men do not have a 'fertile window' because sperm is continually formed and stored in the testicles, ready to be used at any time.
Men do not have a "fertile window" per se as sperm is continually formed and stored in the testes. Healthy sperm is viable anytime under normal health circumstances. Sperm has the ability to live for up to six days in the uterus.
However, the number and quality of the sperm declines with your age. From a biological standpoint, experts recommend a man is best suited to fatherhood from his late 20s to early 30s. It is still possible for men to father a child in their 50s and older.
One of the main issues that commonly affect a man's fertility is the quantity and the quality of their semen. This means that testing your semen should be one of the first things you do if you suspect you are having problems with your fertility as a man. Semen testing usually takes place in a clinal laboratory.
Unlike females, males are not ovulating monthly or releasing an egg from their sex glands. While a woman's monthly cycle is very hormonally regulated, men produce sperm and testosterone all year long, a process that isn't regulated monthly. However, some researchers consider male hormones to be regulated seasonally.
The male hormone cycle
When we talk about a man's 'cycle', we are talking about their testosterone cycle. Men actually experience a full testosterone cycle every 24 hours, with peaks and troughs in testosterone levels during this time which affect mood, attitudes and behaviour.
We usually talk about a woman's biological clock ticking. Pregnancy after 35 can entail physical complications that can hamper fertility. Turns out, it is not just women; men have a biological cycle too.
Men start losing their fertility at age 40.
In a study of more than 1,900 couples, irrespective of the woman's age, IVF attempts involving men 40 or older failed 70 percent more often than IVF attempts involving men younger than 30. Previous theory: Older men produce fewer kids because they get less sex.
The concentration of sperm is what makes the semen cloudy and thick, so if your ejaculate is watery it is possible that you have a low sperm count. This doesn't mean you're infertile (so precautions to prevent pregnancy still need to be taken for couples that don't want to get pregnant).
Signs and Symptoms of Infertility in Men
Trouble ejaculating – either no ejaculation or reduced volume of semen. Loss of libido or sexual desire / arousal. Pain or discomfort in the testicles or area surrounding the testicles. Growth of breast tissue in men (gynecomastia)
Sperm motility
Whereas sperm quality is at the best levels between ages 30-35, motility is best before age 25. And as with semen quality, motility declines dramatically after age 55.

Dr. Frederick agrees that semen in the early morning (before 7:30 a.m.) has the highest sperm concentration, total sperm count and normal morphology compared to the other times of the day.

Previous studies have shown they are seen more attractive by men when ovulating," said Dr Hannah Rowland from University of Cambridge.
A woman is most fertile during ovulation. For a woman with 28 to 30 days menstrual cycle, ovulation takes place during the 10th to the 14th day. But there are still chances to of getting pregnant till the 21st day. So days 1 to 7 and 14 days before your periods are considered to be safe days.
Some research says that yes, sperm may be more potent in the morning. But other studies suggest it's more potent in the afternoon or that it doesn't change at all. Whatever the case, it's highly unlikely that the time of day you have sex will affect your chances of conceiving.
Semen can become watery or thinner than usual if someone masturbates or engages in sexual activity multiple times each day. In this case, abstaining from sexual activity for a few days may help treat the issue. Watery semen can sometimes indicate that a person has a low sperm count or reduced semen quality.
Some studies suggest that moderate ejaculation (2–4 times per week) is associated with a lower prostate cancer risk. However, ejaculating more often doesn't mean your cancer risk drops even more.
Semen, or cum, typically has a faint smell caused by a mixture of chemicals, such as citric acid and calcium. It may also smell slightly sweet, as it contains fructose. A strong, fishy odor, might stem from an infection, while a very sweet smell may be a sign of diabetes.
Semen is normally a whitish-gray color. Changes in semen color might be temporary and harmless or a sign of an underlying condition that requires further evaluation. Possible causes, by color, include: Red semen.
According to the authors of one 2011 study on the subject, “Gender and baby longing is a question of degrees, not of exclusive categories. Men may experience a 'slight rise of temperature' if not full-blown 'baby fever.
The Male Hormonal Cycle
Men have a 24-hour cycle, where their testosterone levels are highest in the morning and lowest in the night. Which essentially means that they are perfectly in sync with the standard workday. The morning is a great time for men as their testosterone levels are at their peak and so is the man.
While it's not impossible to avoid, many dads experience this change – and there is real data to fit this narrative. Several years ago, Northwestern University published a study of 10,000 men that showed fathers gained more than 4 pounds after having their first child.
