The Heart-Fertility Link: How Cardiovascular Health Impacts Reproductive Potential

When conversations about fertility take place, the focus is usually on reproductive organs, hormones, or lifestyle factors such as diet and exercise. One aspect that is often overlooked is the role of the heart. Research has shown that cardiovascular health has a significant influence on reproductive outcomes, and understanding this connection is crucial for comprehensive reproductive care.

What Is The Link Between Cardiovascular Health And Reproductive Health?

Speaking to Onlymyhealth, Dr Kshitiz Murdia- CEO & Whole Time Director of Indira IVF Hospital Limited shares, “Reproduction relies heavily on proper blood circulation. The cardiovascular system acts as the body’s delivery network, carrying oxygen, nutrients, and hormones to the reproductive organs. When the heart or blood vessels are not functioning optimally, this delivery system is disrupted, which can directly affect fertility.”

Studies indicate that women with higher cardiovascular health scores, measured using the American Heart Association’s Life’s Essential 8 metrics, are much less likely to experience infertility.

“Women with higher scores have up to a 41 percent lower risk of infertility compared to those with lower scores, highlighting the close link between heart health and reproductive potential,” shares Dr Murdia.

Risk Of Preeclampsia In People Diagnosed With Arterial Stiffness

Research published in Signal Transduction and Targeted Therapy also shows that arterial stiffness, a marker of vascular aging and cardiovascular risk, can significantly impact pregnancy outcomes. Women who develop complications such as preeclampsia often show increased arterial stiffness even before clinical symptoms appear. Pulse wave velocity measurements, the gold standard for assessing arterial stiffness, have proven effective in predicting pregnancy-induced hypertension.

Population-based studies have further demonstrated the connection between male fertility and overall health. We have simplified the information in pointers for your easy understanding:

• Men with infertility tend to have higher rates of metabolic and cardiovascular disorders compared to fertile men of similar age.
• Endothelial dysfunction, a condition in which the blood vessel lining is impaired, plays a key role in linking cardiovascular disease, erectile dysfunction, and male infertility.
• Reduced nitric oxide production associated with this condition hinders blood flow necessary for both erections and sperm production.
• Erectile dysfunction can therefore act as an early signal of underlying vascular issues and may even precede more severe cardiovascular events.

“Notably, the penile arteries are comparable in size to coronary arteries. As a result, atherosclerotic changes in the penile arteries may reflect early coronary artery disease. In clinical practice, men presenting with erectile dysfunction may benefit from cardiovascular assessment, including a lipid profile to evaluate dyslipidemia, and, where indicated, a 2D echocardiogram to assess cardiac function,” shares Dr Murdia.

How Does Heart Influence Fertility?

The heart also influences fertility through hormonal regulation. Estrogen, progesterone, and testosterone are essential for ovulation, sperm production, and overall reproductive function. Heart conditions or medications used to treat them can disrupt these hormone levels, which may affect fertility. Lifestyle factors further contribute to this link.

Maintaining a healthy weight, engaging in regular physical activity, and following a balanced diet support both cardiovascular and reproductive health. Conversely, smoking, excessive alcohol consumption, and a sedentary lifestyle can damage the heart and reduce fertility.

Final Word

Dr Murdia concludes by saying that the connection between heart health and fertility demonstrates that the body functions as an integrated system. Prioritising cardiovascular wellness not only helps prevent heart disease but also enhances the chances of conception and a healthy pregnancy. Integrated care approaches that address heart and reproductive health simultaneously can optimize fertility outcomes while reducing long-term health risks. As research continues to uncover the intricate connections between cardiovascular and reproductive function, maintaining heart health remains a key factor for those planning parenthood.
