When you\u2019ve been unable to conceive, a fertility specialist is likely to prescribe you a medication to help increase your chances of becoming pregnant.<\/p>\n\n\n\n<p>Letrozole is a common drug you can use right from the start of a fertility treatment journey. It\u2019s one of the best drugs used to help fight <a href=\"https:\/\/myfertilitycloud.com\/getting-pregnant-with-unexplained-infertility\">infertility<\/a> and increase the chance of conception. Some studies show that it\u2019s the best one on the market. But what is it exactly? And how does it compare to others? That\u2019s what we\u2019re here to help you learn.<\/p>\n\n\n\n<p>Read on to learn about how letrozole helps increase fertility and how it compares to other infertility treatment options, such as clomiphene. You\u2019ll also learn about combining letrozole with other infertility treatments to boost efficacy.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-what-is-letrozole\"><strong>What is letrozole?<\/strong><\/h2>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"The Untold Secrets of Letrozole for Infertility\" width=\"500\" height=\"281\" src=\"https:\/\/www.youtube.com\/embed\/B5ZNLviMXYs?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n\n\n\n<p>Letrozole is the generic name for Femara, and it\u2019s a medicine that women use for multiple purposes. Even though it\u2019s often recommended for <a href=\"https:\/\/myfertilitycloud.com\/blog\/signs-of-infertility-understanding-the-silent-struggle\">infertility<\/a> treatment, its main purpose is to help treat breast cancer.<\/p>\n\n\n\n<p>It\u2019s an oral drug that\u2019s primarily used as a treatment for early breast cancer, specifically hormone-dependent breast cancer. It\u2019s usually prescribed to women who have gone through menopause and have already received other cancer treatments, such as radiation. The drug reduces the level of estrogen in the female\u2019s body, which is a sex hormone that can stimulate the growth of some breast cancers.<\/p>\n\n\n\n<p>Letrozole is also one of the first treatment options used for people struggling with infertility. It\u2019s prescribed as part of ovarian stimulation. In a similar way that the medication lowers estrogen to reduce breast cancer cell growth, the reduced estrogen can benefit females with infertility as well.<\/p>\n\n\n\n<p>The estrogen is reduced by blocking the aromatase inhibitor enzyme that helps create it. The decrease in estrogen can help the brain release other hormones that are needed for conception. One of the hormones it can trigger is the follicle-stimulating hormone (FSH). FSH helps to increase the number of ovulated eggs from the fallopian tube. Its purpose is to help the immature eggs grow.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-letrozole-versus-clomiphene\">Letrozole versus clomiphene<\/h2>\n\n\n\n<p>Even though letrozole is a common drug used for infertility, it\u2019s not the only option for ovarian stimulation. Your doctor may also recommend clomiphene citrate, which is the generic name for Clomid, another type of oral medication used to stimulate ovulation. They will determine which works best for you based on your medical history.<\/p>\n\n\n\n<p>Clomiphene works similarly to letrozole as it also reduces the estrogen in the body to stimulate other hormones. But while letrozole blocks the aromatase inhibitor enzyme, clomiphene citrate blocks the brain\u2019s estrogen receptor.<\/p>\n\n\n\n<p>Clomiphene has been around much longer than letrozole, first making its appearance on the market back in <a href=\"https:\/\/pharmaceutical-journal.com\/article\/opinion\/frank-p-palopoli-1922-2016#:~:text=Clomifene%2C%20also%20known%20as%20Clomid,Organization's%20list%20of%20essential%20drugs.\">1967<\/a>. Letrozole was approved by the FDA several decades later in <a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/11895893\/#:~:text=In%201998%2C%20letrozole%20was%20approved,second%2Dline%22%20treatment).\">1998<\/a>.<\/p>\n\n\n\n<p>Overall, the efficacy of letrozole and clomiphene is relatively similar, but letrozole tends to have fewer side effects. For instance, clomiphene can cause hot flashes and constipation.<\/p>\n\n\n\n<p>Letrozole is also preferred for females with infertility that stems from <a href=\"https:\/\/myfertilitycloud.com\/getting-pregnant-with-pcos\">PCOS<\/a>. In fact, <a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC4175743\/\">a study<\/a> showed a successful pregnancy rate of about 28% with letrozole in females with PCOS, as opposed to a 19% pregnancy rate with clomiphene.<\/p>\n\n\n\n<p>Pregnancies that stem from ovarian stimulation usually occur in the first three months, regardless of which medication is prescribed.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-combining-letrozole-with-other-infertility-treatments\"><strong>Combining letrozole with other infertility treatments<\/strong><\/h2>\n\n\n\n<p>When you start your fertility journey, you may begin with ovarian stimulation, OS, using letrozole, unless your doctor believes that your body will respond better to clomiphene citrate. The efficacy of OS can be boosted by combining it with other treatment options.<\/p>\n\n\n\n<p>To help infertility, your fertility specialist may recommend combining letrozole with intrauterine insemination, or IUI. This procedure involves sperm being implanted into the uterus to increase the number of healthy sperm cells that could potentially fertilize an egg. When OS and IUI are used at the same time, they have an <a href=\"https:\/\/www.nepjol.info\/index.php\/AJMS\/article\/view\/40842#:~:text=Background%3A%20A%20combination%20of%20controlled,20%25%20depending%20on%20many%20factors.\">efficacy rate of up to 20%<\/a>.<\/p>\n\n\n\n<p>Another common infertility treatment that can be partnered up with OS and\/or IUI is a trigger shot of human chorionic gonadotropin (HCG). This is a hormone that assists in the release of multiple mature eggs that are waiting in your ovaries. <a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC5641441\/\">A study<\/a> showed that when an HCG is administered in conjunction with IUI, there\u2019s a pregnancy rate of about 18.2%.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-fertility-cloud-can-prescribe-you-letrozole-to-treat-your-infertility\"><strong>Fertility Cloud can prescribe you letrozole to treat your infertility<\/strong><\/h2>\n\n\n\n<p>Infertility is already difficult to deal with, and it can be even more frustrating when you\u2019re worried about how successful a certain treatment option will be in helping to boost the possibility of conception. The good news is that letrozole is so widely recommended for infertility because it has a high efficacy level.<br>If you\u2019d like to look into letrozole for infertility, <a href=\"tel:+1707-361-6339\">contact our team<\/a> by phone today for more information or <a href=\"https:\/\/myfertilitycloud.com\/book-appointment\">book an initial appointment<\/a> online with a fertility specialist.<\/p>\n<div class='sib-form' id='sib-form-main-container' style='text-align: center; background-color: #EFF2F7;'>\n                                <div id='sib-form-container' class='sib-form-container'>\n                                    <div id='error-message' class='sib-form-message-panel' style='font-size:16px; text-align:left; font-family:Helvetica, sans-serif; color:#661d1d; background-color:#ffeded; border-radius:3px; border-color:#ff4949;max-width:540px;'>\n                                        <div class='sib-form-message-panel__text sib-form-message-panel__text--center'>\n                                            <svg viewBox='0 0 512 512' class='sib-icon sib-notification__icon'>\n                                                <path d='M256 40c118.621 0 216 96.075 216 216 0 119.291-96.61 216-216 216-119.244 0-216-96.562-216-216 0-119.203 96.602-216 216-216m0-32C119.043 8 8 119.083 8 256c0 136.997 111.043 248 248 248s248-111.003 248-248C504 119.083 392.957 8 256 8zm-11.49 120h22.979c6.823 0 12.274 5.682 11.99 12.5l-7 168c-.268 6.428-5.556 11.5-11.99 11.5h-8.979c-6.433 0-11.722-5.073-11.99-11.5l-7-168c-.283-6.818 5.167-12.5 11.99-12.5zM256 340c-15.464 0-28 12.536-28 28s12.536 28 28 28 28-12.536 28-28-12.536-28-28-28z' \/>\n                                            <\/svg>\n                                            <span class='sib-form-message-panel__inner-text'>\n                                                      Your subscription could not be saved.
