You and your partner are still together. You still love each other. Something has gone wrong in how you talk, sex has become a transaction or has stopped, small irritations now feel like accusations, and you cannot remember the last time you laughed in the same room. You came here partly looking for permission to admit this is hard, and partly for what to actually do about it. Both are valid.
I want to say this before any framework. When a marriage bends under TTC, it is rarely because the marriage is weak. TTC under chronic stress is one of the most predictable relational strain events in adult life. Pooled cohort data from Peterson and others suggest clinically significant couple distress in 30 to 40 percent of couples after twelve months of unsuccessful TTC.4 Schmidt's longitudinal work tracked communication patterns and showed that the quality of how a couple talks about fertility, more than the financial cost, predicts who drops out and who stays in.5 Many couples assume that the strain means something is wrong with them as a couple. Often it means there is something heavy in the room and the couple is intact enough to feel it. The dangerous outcome is not the strain itself. It is the silence that follows, and the avoidance of repair.
What chronic TTC stress does to couples
John Gottman's longitudinal couples research, conducted over four decades with thousands of couples followed for years to decades, identifies four behavioural patterns most predictive of relationship breakdown: criticism, contempt, defensiveness, and stonewalling. He has called these the Four Horsemen of the Apocalypse.1 Contempt and stonewalling are the most lethal; contempt because it signals one partner now looks down on the other, stonewalling because it ends repair entirely. Under chronic stress all four patterns increase, and TTC is a chronic stress event by any reasonable definition.
Gottman's protective patterns, derived from observations of couples whose relationships strengthened rather than broke under stress, include a ratio of positive to negative interactions during conflict of approximately five to one, repair attempts during arguments (any move that breaks an escalation cycle), soft start-ups instead of harsh ones in difficult conversations, and a documented willingness to accept influence from your partner.2
Beyond Gottman, the relational research base in fertility-specific populations is consistent. Bidirectional spillover of distress is well-documented: one partner's depression affects the other's stress response within days, and one partner's withdrawal predicts the other's symptomatic increase. The Boivin 2011 meta-analysis in the BMJ examined the relationship between emotional distress and ART outcomes and found that, contrary to popular narrative, distress does not meaningfully reduce success rates of treatment.7 That finding matters here because it removes the additional pressure of "if I am too stressed I will fail this cycle." You will not. You may still be suffering, and that suffering deserves response on its own terms.
The five most common couple patterns I see in long TTC
These are not from the research literature directly. They are clinical observations from clinic across many couples doing this for a long time.
Scheduled sex becoming the only sex: intercourse compressed into a fertile window kills spontaneity over time. Couples often stop having non-fertile-window sex because "what is the point," which then makes the fertile-window itself feel transactional. The conversation that opens this pattern is, "When was the last time we had sex that wasn't about trying to conceive?"
Asymmetric grief: one partner is open about feelings, the other compartmentalises. Each interprets the other's pattern as wrong rather than different. Neither pattern is wrong. The mismatch is real, and Schmidt's work documents this asymmetry as a primary predictor of communication breakdown.5
Avoidance of fertility conversation: once 90 percent of communication has become fertility-related, both partners stop talking about it altogether to escape. Now nothing is being said, and the avoidance feels like distance.
Financial conflict masking emotional conflict: arguments about IUI or IVF cost are often arguments about who is committed, who is sacrificing, and who is being heard. The financial conversation is real and needs its own session. The emotional conversation underneath needs its own session too.
Sex on the table only for the embryo transfer rule: the specific clinical question about when to abstain becomes symbolic for many couples, because it is the only sex-related question the relationship has been having for months.
Sex during TTC, the specific FET question and the broader one
The narrow clinical answer to the search query when to stop having sex before frozen embryo transfer: most clinics advise no penetrative intercourse for 24 to 48 hours before the transfer and for the immediate 24 to 48 hours after, with specifics that vary between programmes. The rationale is twofold: to reduce uterine contractions immediately around the implantation window, and to reduce infection risk near catheter passage.
Variation exists. Some clinics permit intercourse until the morning of transfer; others request three to four days of abstinence. Some advise abstaining until after the beta-hCG result, particularly with frozen embryo transfers. Always confirm with your specific clinic, in writing if you have a printed protocol. The same applies to fresh transfers, when stop-sex guidance is often tighter because of ovarian discomfort and infection risk after retrieval.
A similar question applies after IUI: many clinics recommend resuming penetrative intercourse on the day of IUI or the day after, partly because additional intercourse near ovulation may modestly improve outcomes. Other clinics recommend abstaining for 24 to 48 hours. Ask yours.
The harder question is the one underneath. Many couples come into a transfer cycle having not had non-fertility-related sex in six months. The transfer abstinence is not the relationship problem. The broader avoidance is. If "when was the last time we had sex that was not about trying to conceive" returns an answer like "I cannot remember," that is a couples-therapy conversation. It is not a moral failure. It is a documented relational pattern in long TTC, and it responds to attention.
What repair actually looks like
The Gottman framework gives the most practical, evidence-tested tools, and the Emotionally Focused Therapy (EFT) framework from Sue Johnson adds the attachment-based layer that explains why some of the patterns repeat even after couples know about them.3
Soft start-up: begin hard conversations with "I" statements, not "you" accusations. "I felt invisible when..." rather than "You never...". Gottman's research suggests the first three minutes of a difficult conversation predict the trajectory of the next hour.2 Practice the first sentence, before you are in the moment.
Repair attempts during conflict: any move that breaks the escalation cycle. Humour, if it can be done without sarcasm. Naming the moment ("we are going around in circles, can we pause"). Physical touch, if the relationship can hold it under tension. A 20-minute break with a fixed return time. Couples who attempt repair recover more reliably regardless of the technical quality of the attempt.
Five-to-one positive-to-negative ratio: the goal is not "no conflict." Meaningful relationships have conflict. The goal is meaningfully more positive moments (humour, affection, gratitude, presence) than negative ones, especially during conflict. Five-to-one is approximate; the principle is that the relationship's emotional bank account stays in surplus.
State of the union conversation: a weekly 30-minute structured conversation with four parts: what worked this week, what did not, what I appreciate about you, and what I want to bring up. Predictable, contained, not improvised in the moment. The structure itself reduces the cognitive load of figuring out when to talk about hard things.
Stress-reducing conversation: twenty to thirty minutes daily where each partner talks about external stress (work, family, anything not fertility-specific) and the other listens without offering solutions. Counter-intuitively important for fertility couples, because so much of the relational space has been fertility-only that there is no room left for ordinary partnership.
Repair after rupture: when something has gone wrong, name it, name the impact on the other person, take responsibility for your part, and reconnect. Do not wait for the next argument. Repair is its own intervention, and the repair attempt itself is more important than its elegance.
When to escalate to couples therapy
I would book a couples-therapy consultation when several of the following are true, not all of them.
Conversations have narrowed to fertility-only, even if neither of you intended that. You can identify multiple Four Horsemen in your recent arguments, especially contempt or stonewalling. Sex outside the fertile window has stopped for six or more months. One of you has had an emotional or physical affair, or has seriously considered one. One of you has said "I do not know if we can do this together" in a non-rhetorical way. A loss has happened and one or both of you are stuck in it.
Booking a couples-therapy intake does not require a crisis. Most couples who benefit most from therapy started before the breaking point, not after.
What couples therapy looks like
The two evidence-based modalities most relevant in TTC populations are EFT and the Gottman Method.
Emotionally Focused Therapy (EFT): Sue Johnson's attachment-based model. Strong evidence in couples under chronic medical or life stress, including fertility populations.3 EFT works by mapping each partner's attachment-related fears and the cycles of pursuit and withdrawal those fears create, then restructuring the cycle through specific in-session experiences. A typical course is eight to twenty sessions. EFT-certified therapists are listed in the ICEEFT (International Centre for Excellence in EFT) directory.
Gottman Method: structured, behaviour-and-skills-based, with a defined assessment phase at the start that includes questionnaires and a couple's history. Strong evidence over decades.1 Typically ten to twenty sessions. Gottman-certified therapists are listed at the Gottman Institute's therapist directory.
Cognitive-behavioural couples therapy: good for symptom-focused work where one partner has clinical depression or anxiety alongside relational strain.
For finding a therapist, the AAMFT (American Association for Marriage and Family Therapy) directory, ICEEFT, the Gottman therapist directory, BACP (British Association for Counselling and Psychotherapy) in the UK, and BICA (UK fertility-specific) are all practical starting points. The cost and access notes from TTC grief and when to see a therapist apply equally here.
Red flags for relationship safety
Couples therapy is the wrong frame in a few specific situations, and I want to name them explicitly so this post does not paper over them.
Any pattern of intimate partner violence, escalating coercive control, financial control by one partner over the other, or threats of harm: this is not couples-therapy territory. It is individual safety planning. The UK National Domestic Abuse Helpline is 0808 2000 247. The US National DV Hotline is 1-800-799-7233. Country equivalents exist.
One partner threatening self-harm contingent on the other partner's behaviour during a TTC conflict: this is a clinical mental health emergency, not a couples-therapy conflict.
Substance use that has become central to either partner's coping needs to be addressed in its own track, often before or alongside couples work.
What you can do this week
Three concrete things, none of them requiring a therapist.
- Pick one of the Gottman tools above (soft start-up, the 5:1 ratio, the weekly state-of-union conversation) and try it once this week. Not all three at once.
- Have a twenty-minute conversation about something that is not fertility. Set a timer. Do not break the rule. The conversation can be about a film, a friend's news, a memory, a holiday. The content matters less than the practice.
- If you have not had non-fertility-related sex in three or more months, agree on one evening this month that is explicitly off-fertility, no calendar, no timing, no agenda. This is not a guaranteed fix. It is a re-opening of a possibility you may have closed without meaning to.
If after this week you are still in the patterns the post describes, book a couples-therapy intake. Not a crisis. A practical step.
What's normal, what's a red flag
Normal in long TTC is a relationship that feels harder than it did before, with conversations narrower, sex more freighted, and patience for small frictions reduced. Most couples in long TTC describe their relationship in those terms at some point, and most relationships absorb the strain when repair is happening alongside.
Red flags for the relationship include the patterns above, particularly contempt or stonewalling, and any safety-related concerns named in the red-flags section. Take both seriously when they appear.
When a marriage bends under TTC, the work is not to pretend the strain is not there. It is to make repair its own small habit, sooner than feels necessary, and often enough that the silence never gets the last word.

Common questions
When should you stop having sex before a frozen embryo transfer?
Most clinics advise no penetrative intercourse for 24 to 48 hours before the transfer and for the immediate 24 to 48 hours after, with specifics that vary between programmes. The rationale is to reduce uterine contractions around the implantation window and to reduce infection risk near catheter passage. Some clinics permit intercourse until the morning of transfer, others request three to four days of abstinence, and some advise abstaining until after the beta-hCG result. Always confirm with your specific clinic, in writing if you have a printed protocol.
Does stress lower the chance of an IVF cycle succeeding?
The Boivin 2011 meta-analysis in the BMJ examined emotional distress and ART outcomes and found that, contrary to popular narrative, distress does not meaningfully reduce treatment success rates. That removes the added pressure of "if I am too stressed I will fail this cycle." You may still be suffering, and that suffering deserves a response on its own terms.
What are Gottman's Four Horsemen in a relationship?
John Gottman's longitudinal research identifies four behavioural patterns most predictive of relationship breakdown: criticism, contempt, defensiveness, and stonewalling. Contempt and stonewalling are the most lethal, contempt because it signals one partner now looks down on the other, and stonewalling because it ends repair entirely. Under chronic stress all four patterns increase, and TTC is a chronic stress event by any reasonable definition.
When should a couple consider couples therapy during TTC?
Consider booking a consultation when several of these are true, not all of them: conversations have narrowed to fertility-only, you can identify multiple Four Horsemen in recent arguments especially contempt or stonewalling, sex outside the fertile window has stopped for six or more months, one of you has had or seriously considered an affair, one of you has said "I do not know if we can do this together" non-rhetorically, or a loss has happened and one or both of you are stuck in it. Booking an intake does not require a crisis.
When is couples therapy the wrong approach?
Couples therapy is the wrong frame with any pattern of intimate partner violence, escalating coercive control, financial control by one partner, or threats of harm: that is individual safety planning, not couples work. One partner threatening self-harm contingent on the other's behaviour during conflict is a clinical mental health emergency. Substance use that has become central to either partner's coping needs its own track, often before or alongside couples work.
