When preparing for a frozen embryo transfer (FET), many couples and individuals are hyper-focused on medications, appointments, and the emotional aspects of the IVF process. However, one question often arises: “Should we continue having sex before an FET?” While it may seem like a minor aspect in the grand scheme of fertility treatments, recent studies and fertility experts suggest that intercourse leading up to an FET can actually play an important role in the success of the procedure.

What Is a Frozen Embryo Transfer (FET)?

Before diving into the benefits of sex before an FET, let’s briefly recap what the procedure entails. A frozen embryo transfer is a part of the IVF process in which a previously frozen embryo is thawed and then transferred to the uterus. FET has gained popularity due to the increasing success rates of frozen embryo techniques and the flexibility it offers patients in timing the transfer.

The period leading up to an FET typically involves a series of hormonal preparations, such as estrogen and progesterone, to create an optimal uterine lining for implantation. After all the careful planning and preparation, many are eager to do anything that might increase the chances of success. This is where the role of sex comes into play.

The Role of Intercourse Before an FET: What the Science Says

Surprisingly, research has suggested that sexual activity in the days leading up to an embryo transfer could improve implantation rates and overall success. While it may sound unrelated to fertility treatments, here’s why it could make a difference:

1. Enhancing Uterine Receptivity: Studies have indicated that intercourse can influence the immune environment of the uterus. Semen contains various molecules that interact with the female reproductive system, helping to prepare the uterus for embryo implantation. It’s believed that exposure to sperm, particularly the proteins found in semen, can increase the receptivity of the endometrium (the lining of the uterus), making it more welcoming for the embryo to implant.
2. Boosting Natural Hormones: Sex naturally increases the production of oxytocin, often called the “love hormone.” Oxytocin plays a role in stimulating uterine contractions and improving blood flow to the uterus, potentially enhancing the environment for implantation. These mild contractions can help facilitate the embryo’s movement and attachment to the uterine lining.
3. Reducing Stress: The IVF process is known to be emotionally demanding, with stress playing a role in outcomes. Sexual activity releases endorphins, the body’s natural mood enhancers, helping reduce stress and anxiety. Lower stress levels are associated with improved fertility outcomes, as they support hormonal balance and promote overall well-being.
4. Strengthening Partner Connection: In the whirlwind of doctor’s appointments, medication schedules, and treatment protocols, many couples feel a sense of disconnection from each other. Maintaining intimacy through sex can help reinforce emotional bonds and provide comfort during a time that can often feel clinical and detached. Feeling connected to your partner is essential for emotional well-being, which in turn, can positively impact the overall IVF journey.

Timing and Frequency: What’s Recommended?

While the benefits of intercourse leading up to an FET are increasingly recognized, many couples wonder about the specifics—when and how often should they be intimate?

• Timing: It’s often recommended to engage in sexual activity in the days leading up to the FET but avoid it on the day of or immediately after the embryo transfer. The goal is to enhance uterine receptivity before the procedure, but you don’t want to disrupt the embryo’s delicate implantation process.
• Frequency: There’s no set rule for how often couples should have sex before an FET. A couple of times during the days leading up to the transfer could be beneficial, but it’s also important not to add pressure or stress around intercourse. Remember, the purpose is to maintain a healthy, relaxed, and connected environment—both physically and emotionally.

Considerations and Precautions

While sex before an FET may have potential benefits, it’s important to follow the guidance of your fertility specialist, as each patient’s situation is unique. For instance, in cases of recurrent pregnancy loss, certain uterine conditions, or when using donor sperm or eggs, your doctor may provide different recommendations regarding intercourse.

Here are some things to consider:

• Pelvic Rest: In certain medical situations, doctors may recommend pelvic rest, meaning no intercourse, in the days or weeks leading up to or following an FET. This may be advised to minimize the risk of infection, reduce uterine irritation, or prevent premature uterine contractions.
• Consult Your Doctor: It’s always important to communicate with your fertility team about whether sex is advisable in your specific case. If you have concerns or questions, your doctor can provide personalized advice based on your health and treatment plan.

FET Success Is a Team Effort

Preparing for a frozen embryo transfer is both a medical and emotional journey. Sex, while often overlooked, can offer benefits that go beyond physical pleasure. Whether by enhancing uterine receptivity or fostering a deeper connection between partners, intercourse in the lead-up to an FET can play a role in setting the stage for a successful outcome.

As with all aspects of fertility treatment, there’s no one-size-fits-all approach. The journey is deeply personal and can be filled with ups and downs. However, knowing that something as natural as intimacy may contribute to your chances of success can be a comforting and empowering realization.
