Fertility requires a healthy circadian rhythm, which is shaped
by physiological melatonin levels. Any problem with the 24-hour cycle can have
a negative impact on both female and male fertility.
Factors that
prevent fertilisation
Factors include circadian
rhythm disorders caused by jet lag and shift work, which adversely affects
nocturnal melatonin production and ultimately prevents other hormones from
being adequately produced. An impaired circadian rhythm also has a negative
impact on the female menstruation cycle and can cause periods to become
irregular or skipped, which can also have a negative impact on the reproductive
system.
Melatonin and
female fertility
Poor egg quality, often caused
by oxidative stress, is considered to be one of the main causes of female
infertility. With its anti-oxidative and anti-inflammatory properties,
melatonin can prevent cells from being damaged by free radicals, which is
especially important for ovulation. Especially in artificial fertilisation,
eggs are exposed to even greater stresses. Researchers recommend that melatonin
be administered before IVF in this case to improve egg quality.
Melatonin and
male fertility
To improve male
fertility, melatonin not only serves to increase the energy of the spermatozoa
but also makes them faster and more agile. Melatonin also protects sperm from
oxidative stress and improves its quality, which is essential to achieve
successful fertilisation.
