Many people focus on ovulation timing, supplements, or diet when trying to conceive, but few realise how strongly hydration and fertility are connected. The fluids you drink each day influence cervical mucus, hormone balance, egg and sperm quality, and even implantation. At the same time, one common question comes up again and again in clinics: does alcohol affect fertility? The science is clear that drinking can interfere with ovulation, hormone signalling, and reproductive function in both women and men.
Understanding how hydration and fertility interact, and how alcohol impacts the reproductive system, gives you a simple way to support your chances of conceiving whether you are trying naturally, in the two-week wait, or preparing for IVF. Every sip you take helps shape the internal environment where conception happens.
Quick answer: Yes, alcohol affects fertility. Drinking can disrupt ovulation, lower progesterone, reduce embryo implantation rates, impair egg and sperm quality, and increase DNA fragmentation. Hydration, on the other hand, supports cervical mucus, hormone regulation, circulation, uterine lining health, and sperm motility. Consistent hydration and limiting alcohol are two of the simplest lifestyle changes to support fertility.
This guide explains the science and offers practical steps to drink your way to better reproductive health.
Water makes up about 60 percent of the human body and is essential for hormone production, nutrient transport, digestion, and cellular function. For fertility specifically, hydration supports:
Even mild dehydration raises cortisol and affects reproductive hormones. Many women notice that when they drink too little water, cervical mucus becomes sticky and sparse, which can make it harder for sperm to reach the egg.
Hydration also supports thyroid health, which plays a central role in fertility. If you have symptoms that may relate to thyroid imbalance, the guide on how hypothyroidism affects female hormones provides helpful clarity.
When the body is dehydrated, several fertility-related systems slow down:
All of these changes can influence ovulation timing and luteal-phase stability. Some women also feel more fatigued or stressed when dehydrated, which can further affect hormonal balance.
Alcohol affects reproductive hormones almost immediately. It interferes with the hypothalamic-pituitary-ovarian axis, which controls ovulation and menstrual regularity.
Drinking can lead to:
Even moderate drinking during the fertile window can reduce chances of conception. Women undergoing IVF often receive clinic guidance to avoid alcohol entirely for at least a month before stimulation.
Alcohol also raises cortisol, which interacts with reproductive hormones. If you are navigating emotional stress around TTC, you may find comfort in the guide on how men cope with fertility stress, which applies broadly to both partners.
While fertility conversations often focus on women, alcohol significantly affects male reproductive health too.
Alcohol can:
DNA fragmentation reduces the ability of sperm to fertilise the egg and increases the risk of early miscarriage.

Cervical mucus plays a major role in natural conception. It nourishes sperm, helps them move efficiently, and creates a pH environment that supports survival.
When hydration drops, cervical mucus becomes:
This can reduce the likelihood of sperm reaching the egg. Drinking enough water daily is one of the easiest ways to support fertile-quality mucus during the ovulatory window.
Hydration also supports electrolyte balance, which influences cell signalling throughout the reproductive system.
Implantation is a sensitive process that depends on adequate progesterone, balanced immune activity, and a receptive uterine lining.
Alcohol can affect all three by:
This is why clinics often recommend avoiding alcohol throughout the entire implantation period.
If you are preparing for IVF or have experienced challenges in the past, the overview on IVF fertilisation failure provides insight into how lifestyle choices contribute to outcomes.
The two-week wait often feels long and emotionally intense, but hydration is especially important during this time.
Proper hydration supports:
Many women find gentle hydration, herbal teas, and electrolyte-rich foods helpful during these uncertain days.
Eggs and sperm mature over many weeks before an IVF cycle. Alcohol consumed during this period can influence:
Even low levels of drinking can affect IVF outcomes, which is why many clinics recommend temporarily avoiding alcohol for at least one full cycle before stimulation.
Here are the most fertility-supportive hydration choices:
Filtered or tap water
The simplest and safest way to maintain hydration.
Glass-bottled water
Helps avoid exposure to certain endocrine-disrupting chemicals found in plastic.
Herbal teas
Chamomile, ginger, peppermint, and rooibos can support hydration, digestion, and nervous-system regulation.
Hydrating fruits and vegetables
Watermelon, cucumber, oranges, lettuce, and berries add fluids and antioxidants.
Electrolytes (in moderation)
Helpful during exercise, hot weather, or IVF preparation.
Alcohol
Has well-established negative effects on female and male fertility.
Caffeine (over 200 mg per day)
Can act as a mild diuretic and may be associated with increased miscarriage risk.
Sugary drinks
Cause rapid blood sugar spikes that interfere with hormone regulation.
Energy drinks
Often contain high caffeine and artificial additives.
Most adults need around 2 to 2.5 litres of water per day, though needs may increase with:
Hydration checkpoints include:
Your body will usually guide you with clear signals if you learn to notice them.
You can support fertility with small, consistent habits:
Hydration is one of the simplest and most effective natural ways to support fertility.
Does alcohol affect fertility in women?
Yes. Even light to moderate drinking can interfere with ovulation, progesterone production, and implantation. Studies show that alcohol can reduce conception rates during the fertile window and may lead to fewer high-quality embryos during IVF.
How does alcohol affect fertility in men?
Alcohol lowers testosterone, increases oxidative stress in the testes, and can reduce sperm count, motility, and morphology. Heavy or long-term drinking can also raise sperm DNA fragmentation, which makes fertilisation and early embryo development more difficult.
Can I drink alcohol while trying to get pregnant?
Most fertility specialists recommend avoiding alcohol entirely when trying to conceive. If you do drink socially, keep it minimal and avoid drinking during the fertile window and the two-week wait. This helps protect hormone balance and implantation.
Does occasional drinking impact IVF success?
Even occasional alcohol intake in the three months before treatment can lower ovarian response, reduce egg quality, and affect embryo development. Clinics often advise avoiding alcohol for at least one full cycle before stimulation.
Can alcohol delay ovulation?
Alcohol can affect the signals that trigger ovulation by disrupting the hypothalamic-pituitary-ovarian axis. This can lead to delayed or irregular ovulation in some women, especially with frequent or heavy use.
Can men drink alcohol during fertility treatment?
It’s best for male partners to avoid alcohol for at least 2–3 months before trying to conceive or starting IVF. Sperm take around 72 days to develop, so reducing alcohol supports healthier sperm for the full maturation cycle.
Is one glass of wine a week safe for fertility?
While one drink a week is unlikely to cause major harm, there is no proven “safe amount” for fertility. Because alcohol affects hormones, egg quality, and implantation, most experts recommend limiting or avoiding it during preconception.
How long should I stop drinking before trying to conceive?
The ideal window is at least one menstrual cycle for women and three months for men. This supports hormone health, egg development, and sperm maturation.
Does alcohol increase miscarriage risk?
Yes. Alcohol can impair embryo development, raise oxidative stress, and disrupt early hormonal support of pregnancy. These factors contribute to a higher risk of early loss, even at lower levels of intake.
What can I drink instead of alcohol when trying to conceive?
Herbal teas, flavoured sparkling water, coconut water, and non-alcoholic mocktails made from ginger, mint, citrus, or berries are fertility-friendly choices. They hydrate the body, support hormone balance, and avoid the oxidative stress linked to alcohol.
Hydration supports the hormones, tissues, and cellular functions that make conception possible. Alcohol works in the opposite direction, reducing egg and sperm quality, altering hormone balance, slowing implantation, and increasing oxidative stress.
You do not need to be perfect to support your fertility, but consistent choices help your body remain in balance. Whether you are trying to conceive naturally, navigating the two-week wait, or preparing for IVF, what you drink each day makes a meaningful difference.
