Although many people associate these habits with respiratory or cardiovascular risks, their impact on reproductive health is equally concerning. In both men and women, smoking or vaping can negatively affect the quality of eggs, sperm, and even embryo implantation.<\/p>\n\n\n\n<p>In this post, we explain how these substances interfere with fertility and why quitting smoking is recommended if you\u2019re trying to conceive\u2014especially if you\u2019re undergoing assisted reproduction treatment.<\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\">Tobacco and female fertility: a threat to ovarian reserve<\/h3>\n\n\n\n<p>Smoking cigarettes accelerates ovarian aging. On average, women who smoke experience <strong>early menopause<\/strong> between 1 and 4 years earlier than non-smokers. This is because tobacco toxins\u2014such as nicotine, cadmium, and aromatic hydrocarbons\u2014directly affect ovarian follicles.<\/p>\n\n\n\n<p>Additionally, tobacco alters endometrial blood flow and can reduce implantation rates in treatments such as <a href=\"https:\/\/gravida.com\/en\/assisted-reproduction-treatments\/in-vitro-fertilization\/\"><strong>in vitro fertilization (IVF)<\/strong><\/a>. It also increases the risk of ectopic pregnancy, miscarriage, and obstetric complications.<\/p>\n\n\n\n<p><strong>Effects of tobacco on female fertility:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Reduction of ovarian reserve.<\/li>\n\n\n\n<li>Hormonal alterations.<\/li>\n\n\n\n<li>Decreased endometrial receptivity.<\/li>\n\n\n\n<li>Increased oxidative stress in reproductive cells.<\/li>\n\n\n\n<li>Higher risk of implantation failure in IVF treatments.<\/li>\n<\/ul>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\">What about vaping?<\/h3>\n\n\n\n<p>Although many believe that vaping (e-cigarettes) is a \u201csafer alternative,\u201d several recent studies show that <strong>vaping also negatively affects fertility<\/strong>.<\/p>\n\n\n\n<p>The liquids used in vaping devices often contain <strong>nicotine, propylene glycol, glycerin, and other compounds<\/strong> whose inhalation can have effects similar to traditional tobacco. Moreover, since they are not uniformly regulated, the levels of these substances can vary significantly between brands.<\/p>\n\n\n\n<p>In women, vaping has been shown to <strong>affect follicular development and egg quality<\/strong>, while in men it can alter spermatogenesis.<\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\">Tobacco and male fertility: how it affects sperm<\/h3>\n\n\n\n<p>In men, tobacco directly impacts semen quality. It has been shown that smoking reduces the <strong>number of sperm cells<\/strong>, as well as their motility and normal morphology. It also increases <a href=\"https:\/\/gravida.com\/blog\/reducir-fragmentacion-adn-espermatico\/\">sperm DNA fragmentation<\/a>, a factor that can hinder fertilization and proper embryo development.<\/p>\n\n\n\n<p><strong>Main effects of tobacco on male fertility:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Decreased sperm count.<\/li>\n\n\n\n<li>Poor sperm motility.<\/li>\n\n\n\n<li>Morphological abnormalities.<\/li>\n\n\n\n<li>Increased sperm DNA damage.<\/li>\n\n\n\n<li>Higher oxidative stress in semen.<\/li>\n<\/ul>\n\n\n\n<p>These effects not only make natural conception more difficult but also <strong>reduce the <\/strong><a href=\"https:\/\/gravida.com\/en\/blog\/success-rates-gravida\/\"><strong>success rates<\/strong><\/a><strong> of assisted reproduction treatments<\/strong>.<\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\">How long before trying to conceive should you quit smoking?<\/h3>\n\n\n\n<p>Ideally, you should <strong>quit the habit between 3 and 6 months before trying to conceive<\/strong>. The body needs time to detoxify and restore reproductive function, both at the ovarian and testicular level.<\/p>\n\n\n\n<p>In women, this period helps improve egg quality and endometrial receptivity. In men, since the sperm production cycle lasts about 74 days, this timeframe is essential to regenerate healthier cells.<\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\">Smoking or vaping during assisted reproduction treatment?<\/h3>\n\n\n\n<p>At Gravida, we recommend <strong>completely avoiding tobacco and vaping during any assisted reproduction treatment<\/strong>, both for women and men.
