2. Abstract
Men produces the millions of sperm everyday and it continues till they are alive.
Although sperm is still being produced, the quality changes. The number of sperm
produced, called the concentration or count, how well the sperm swim, known as their
motility, and the shape of the sperm, called their morphology, are all known to change
with age. Healthy BMI score for males is between 18.5 and 25.0.BMI can be used to
determine whether a person is underweight, normal weight, overweight, obese, or
morbidly obese.The BMI categories for males are as follows: <18.5 Underweight,18.5
- 25 Normal weight,25 - 29 Overweight,30 Obese and 40 Morbidly obese. The quality
of semen parameters plays a critical role in male fertility, influenced by various factors
including age and Body Mass Index (BMI). This review examines the independent and
combined effects of age and BMI on sperm count, motility, morphology, DNA integrity,
and hormonal profiles. Aging is associated with gradual declines in sperm count,
motility, and morphology, alongside increased DNA fragmentation, reflecting
diminished reproductive potential. Conversely, BMI exhibits a U-shaped relationship
with semen parameters, where both low and high BMI levels can negatively impact
sperm quality through hormonal disruptions and altered sperm production. The
interaction between age and BMI further exacerbates these effects, potentially
compounding fertility challenges. Understanding these relationships underscores the
importance of maintaining a healthy weight and lifestyle to preserve optimal semen
quality and enhance reproductive outcomes across all stages of adulthood.

3. OBJECTIVE
The aim of the topic is to detect the impact of age and BMI on
semen parameter.
On the basis of the study, we just wanted to find out that if there
is increase or decrease in age or BMI, there is positive or negative
impact on semen parameter like ( count, motility, morphology).

BMI = WEIGHT ( IN KILOGRAMS )/
HEIGHT ( IN METER)
METHODOLOGY

6. SEMEN PARAMETER

7. SEMEN PARAMETER
MACROSCOPIC
ANALYSIS
VOLUME – With
the help of
syringe
•Appearance –On
the basis of colour
of semen sample.
•Viscosity–When
the liquefaction is
complete, the
sample is allowed
to drop by the
force of gravity
through a pipette.

MICROSCOPIC ANALYSIS
Count – By placing one drop on the centre of the makler chamber

10. SEMEN PARAMETER
Morphology : sperm morphology specifically refers to the shape of
the sperm , ideally with a single oval-shaped head, neck or
midpiece and a single tail.
oval-shaped head (3–5μm length and 2–3μm width)
a midpiece (7–8μm)
tail (45μm)
