Is Sex for Reproduction About to Become Extinct?
A healthy fetus in utero at 22 weeks.
There are lots of great reasons we humans have sex. We mostly do it to pair bond, realize our primal urges, and feel good. Once in a while, we also do it to make babies. As the coming genetic revolution plays out, we'll still have sex for most of the same reasons we do today. But we'll increasingly not do it to procreate.
Protecting children from harm is one of the core responsibilities of parenting.
Most parents go to great lengths to protect their children from real and imagined harms. This begins with taking prenatal vitamins during pregnancy and extends to having children immunized and protected from exposures to various diseases and dangers. Most of us look askance for good reason at mothers who abuse controlled substances during their pregnancies or parents who choose to not immunize their children. Protecting children from harm is one of the core responsibilities of parenting.
In the United States today, up to two percent of babies are estimated to be born with rare genetic diseases caused by single gene mutations. Sickle cell disease, Tay-Sachs, and Huntington's disease are among the more well-known examples of these, but the list runs to the thousands. Many babies born with these disorders suffer terribly, some die young, and nearly all spend big chunks of their lives struggling through the medical system.
Increasingly, however, many of these single-gene mutation diseases and other chromosomal disorders like Down syndrome are being identified in non-invasive prenatal tests performed on expectant mothers at the end of their first trimester of pregnancy. Knowing the hardship that children born with these types of disorders will likely face, majorities of these women in countries around the world are choosing to terminate pregnancies once these diagnoses have been made. Whatever the justification and whatever anyone's views on the morality of abortion, these decisions are inherently excruciating.
A much smaller number of prospective mothers, however, are today getting this same information about their potential future children before their pregnancies even begin. By undergoing both in vitro fertilization (IVF) and preimplantation genetic testing (PGT), these women are able to know which of the eggs that have been surgically extracted from them and fertilized with their partner or donor's sperm will carry the dangerous mutations. The in vitro embryos with these disorders are simply not implanted in the expectant mother's womb.
It would be monstrous to assert that an existing person with a deadly disease has any less right to thrive than anyone else. But it would also be hard to make a case that parents should affirmatively choose to implant embryos carrying such a disease if given the option. If prospective parents are already today choosing not to implant certain embryos based on our preliminary understanding of disease risk, what will happen when this embryo selection is based on far more information than just a few thousand single gene mutation diseases?
Our ability and willingness to make genetic alterations to our future children will grow over time along with our knowledge and technological ability.
When the first human genome was sequenced in 2003, the race to uncover the mysteries of human genetics had only just begun. Although we still know very little about our genetics relative to the complexity of the genome and even less compared to the broader ecosystem of our biology, the progress toward greater understanding is astounding. Today, the number of single gene mutation diseases and relatively simple genetic traits that can be predicted meaningfully from genetic data alone is already significant.
In the not-distant future, this list will grow to include complex diseases and disease propensities, percentage probabilities of living a long and healthy life, and increasingly the genetic component of complex human attributes like height, IQ, and personality style. This predictive power of genetic analysis will funnel straight into our fertility clinics where prospective parents choosing embryos will be making ever more consequential decisions about the genetic components of the future lives, health, and capabilities of their children.
Our understanding of what the genes extracted from early stage pre-implanted embryos are telling us will be only one of the rocket boosters driving assisted reproduction forward. Another will be the ability to induce adult cells like skin and nucleated blood cells into stem cells and then turn those stem cells into egg progenitor cells and then ultimately eggs. This will not only eliminate the need for hormone treatments and surgery to extract human eggs but also make it easy and cheap to generate an unlimited number of eggs from a given woman.
The average woman has around fifteen eggs extracted during IVF but imagine what generating a thousand eggs will do to the range of possibilities that could be realized through pre-implantation embryo selection. Each of these thousand eggs would be the natural offspring of the two parents, but the variation between them would make it possible to choose the ones with the strongest expression of the genetic component of a particular desired trait – like those with the highest possible genetic IQ potential.
Another rocket booster will be the application of gene editing technologies like CRISPR to edit the genomes of pre-implanted embryos or of the sperm and eggs used to create them. Just this week, Chinese researchers announced they had used CRISPR to edit the CCR5 gene in the pre-implanted embryos of a pair of Chinese twins to make them immune to HIV, the first ever case of gene editing humans and a harbinger of our genetically engineered future. The astounding complexity of the human genome will put limits on our ability to safely make too many simultaneous genetic changes to human embryos, but our ability and willingness to make these types of alterations to our future children will grow over time along with our knowledge and technological ability.
With so much at stake, prospective parents will increasingly have a stark choice when determining how to conceive their children. If they go the traditional route of sex, they will experience both the benign wisdom and unfathomable cruelty of nature. If they use IVF and increasingly informed embryo selection, they will eliminate most single gene mutation diseases and likely increase their children's chances of living a longer and healthier life with more opportunity than their unenhanced peers. But the optimizing parents could also set up their children for misery if these children don't particularly enjoy what they have been optimized to become or see themselves as some type of freakish consumer product with emotions.
Conceiving though sex will come to be seen more and more like not immunizing your children is today, a perfectly natural choice that comes with a significant potential risk and expense.
But although there will be pros and cons on each side, the fight between conception through good old-fashioned sex and conception in the lab will ultimately not be fair. Differences and competition within and between societies will pressure parents and societies to adopt ever more aggressive forms of reproductive technology if they believe doing so will open possibilities and create opportunities for the next generations rather than close them.
Conception through sex will remain as useful as it has always been but lab conception will only get more advantageous. Over time, only zealots will choose to roll the dice of their future children's health and well-being rather than invest, like parents always have, in protecting their children from harm and helping optimize their life potential. Conceiving though sex will come to be seen more and more like not immunizing your children is today, a perfectly natural choice that comes with a significant potential risk and expense to yourself, your children, and your community.
As this future plays out, the genetics and assisted reproduction revolutions will raise enormous, thorny, and massively consequential questions about how we value and invest in diversity, equality, and our own essential humanity – questions we aren't remotely prepared to answer. But these revolutions are coming sooner than most of us understand or are prepared for so we had better get ready.
Because where this trail is ultimately heading goes well beyond sex and toward a fundamental transformation of our evolutionary process as a species – and that should be everybody's business.

9 Tips for Online Mental Health Therapy
Research shows that, for most patients, online therapy offers the same benefits as in-person therapy, yet many people still resist it. A behavioral scientist explains how you can use it to improve mental health.
Telehealth offers a vast improvement in access and convenience to all sorts of medical services, and online therapy for mental health is one of the most promising case studies for telehealth. With many online therapy options available, you can choose whatever works best for you. Yet many people are hesitant about using online therapy. Even if they do give it a try, they often don’t know how to make the most effective use of this treatment modality.
Why do so many feel uncertain about online therapy? A major reason stems from its novelty. Humans are creatures of habit, prone to falling for what behavioral scientists like myself call the status quo bias, a predisposition to stick to traditional practices and behaviors. Many people reject innovative solutions even when they would be helpful. Thus, while teletherapy was available long before the pandemic, and might have fit the needs of many potential clients, relatively few took advantage of this option.
Even when we do try new methodologies, we often don’t do so effectively, because we cling to the same approaches that worked in previous situations. Scientists call this behavior functional fixedness. It’s kind of like the saying about the hammer-nail syndrome: “when you have a hammer, everything looks like a nail.”
These two mental blindspots, the status quo bias and functional fixedness, impact decision making in many areas of life. Fortunately, recent research has shown effective and pragmatic strategies to defeat these dangerous errors in judgment. The nine tips below will help you make the best decisions to get effective online therapy, based on the latest research.
Trust the science of online therapy
Extensive research shows that, for most patients, online therapy offers the same benefits as in-person therapy.
For instance, a 2014 study in the Journal of Affective Disorders reported that online treatment proved just as effective as face-to-face treatment for depression. A 2018 study, published in Journal of Psychological Disorders, found that online cognitive behavioral therapy, or CBT, was just as effective as face-to-face treatment for major depression, panic disorder, social anxiety disorder, and generalized anxiety disorder. And a 2014 study in Behaviour Research and Therapy discovered that online CBT proved effective in treating anxiety disorders, and helped lower costs of treatment.
During the forced teletherapy of COVID, therapists worried that those with serious mental health conditions would be less likely to convert to teletherapy. Yet research published in Counselling Psychology Quarterly has helped to alleviate that concern. It found that those with schizophrenia, bipolar disorder, severe depression, PTSD, and even suicidality converted to teletherapy at about the same rate as those with less severe mental health challenges.
Yet teletherapy may not be for everyone. For example, adolescents had the most varied response to teletherapy, according to a 2020 study in Family Process. Some adapted quickly and easily, while others found it awkward and anxiety-inducing. On the whole, children with trauma respond worse to online therapy, per a 2020 study in Child Abuse & Neglect. The treatment of mental health issues can sometimes require in-person interactions, such as the use of eye movement desensitization and reprocessing to treat post-traumatic stress disorder. And according to a 2020 study from the Journal of Humanistic Psychology, online therapy may not be as effective for those suffering from loneliness.
Leverage the strengths of online therapy
Online therapy is much more accessible than in-person therapy for those with a decent internet connection, webcam, mic, and digital skills. You don’t have to commute to your therapist’s office, wasting money and time. You can take much less medical leave from work, saving you money and hassle with your boss. If you live in a sparsely populated area, online therapy could allow you to access many specialized kinds of therapy that isn’t accessible locally.
Online options are much quicker compared to the long waiting lines for in-person therapy. You also have much more convenient scheduling options. And you won’t have to worry about running into someone you know in the waiting room. Online therapy is easier to conceal from others and reduces stigma. Many patients may feel more comfortable and open to sharing in the privacy and comfort of their own home.
You can use a variety of communication tools suited to your needs at any given time. Video can be used to start a relationship with a therapist and have more intense and nuanced discussions, but can be draining, especially for those with social anxiety. Voice-only may work well for less intense discussions. Email offers a useful option for long-form, well-thought-out messages. Texting is useful for quick, real-time questions, answers, and reinforcement.
Plus, online therapy is often cheaper than in-person therapy. In the midst of COVID, many insurance providers have decided to cover online therapy.
Address the weaknesses
One weakness is the requirement for appropriate technology and skills to engage in online therapy. Another is the difficulty of forming a close therapeutic relationship with your therapist. You won’t be able to communicate non-verbals as fully and the therapist will not be able to read you as well, requiring you to be more deliberate in how you express yourself.
Another important issue is that online therapy is subject to less government oversight compared to the in-person approach, which is regulated in each state, providing a baseline of quality control. As a result, you have to do more research on the providers that offer online therapy to make sure they’re reputable, use only licensed therapists, and have a clear and transparent pay structure.
Be intentional about advocating for yourself
Figure out what kind of goals you want to achieve. Consider how, within the context of your goals, you can leverage the benefits of online therapy while addressing the weaknesses. Write down and commit to achieving your goals. Remember, you need to be your own advocate, especially in the less regulated space of online therapy, so focus on being proactive in achieving your goals.
Develop your Hero’s Journey
Because online therapy can occur at various times of day through videos calls, emails and text, it might feel more open-ended and less organized, which can have advantages and disadvantages. One way you can give it more structure is to ground these interactions in the story of your self-improvement. Our minds perceive the world through narratives. Create a story of how you’ll get from where you are to where you want to go, meaning your goals.
A good template to use is the Hero’s Journey. Start the narrative with where you are, and what caused you to seek therapy. Write about the obstacles you will need to overcome, and the kind of help from a therapist that you’ll need in the process. Then, describe the final end state: how will you be better off after this journey, including what you will have learned.
Especially in online therapy, you need to be on top of things. Too many people let the therapist manage the treatment plan. As you pursue your hero’s journey, another way to organize for success is to take notes on your progress, and reevaluate how you’re doing every month with your therapist.
Identify your ideal mentor
Since it’s more difficult to be confident about the quality of service providers in an online setting, you should identify in advance the traits of your desired therapist. Every Hero’s Journey involves a mentor figure who guides the protagonist through this journey. So who’s your ideal mentor? Write out their top 10 characteristics, from most to least important.
For example, you might want someone who is:
- Empathetic
- Caring
- Good listener
- Logical
- Direct
- Questioning
- Non-judgmental
- Organized
- Curious
- Flexible
That’s my list. Depending on what challenge you’re facing and your personality and preferences, you should make your own. Then, when you are matched with a therapist, evaluate how well they fit your ideal list.
Fail fast
When you first match with a therapist, try to fail fast. That means, instead of focusing on getting treatment, focus on figuring out if the therapist is a good match based on the traits you identified above. That will enable you to move on quickly if they’re not, and it’s very much worth it to figure that out early.
Tell them your goals, your story, and your vision of your ideal mentor. Ask them whether they think they are a match, and what kind of a treatment plan they would suggest based on the information you provided. And observe them yourself in your initial interactions, focusing on whether they’re a good match. Often, you’ll find that your initial vision of your ideal mentor is incomplete, and you’ll learn through doing therapy what kind of a therapist is the best fit for you.
Choose a small but meaningful subgoal to work on first
This small subgoal should be sufficient to be meaningful and impactful for improving your mental health, but not a big stretch for you to achieve. This subgoal should be a tool for you to use to evaluate whether the therapist is indeed a good fit for you. It will also help you evaluate whether the treatment plan makes sense, or whether it needs to be revised.
Know when to wrap things up
As you approach the end of your planned work and you see you’re reaching your goals, talk to the therapist about how to wrap up rather than letting things drag on for too long. You don’t want to become dependent on therapy: it’s meant to be a temporary intervention. Some less scrupulous therapists will insist that therapy should never end and we should all stay in therapy forever, and you want to avoid falling for this line. When you reach your goals, end your therapy, unless you discover a serious new reason to continue it. Still, it may be wise to set up occasional check-ins once every three to six months to make sure you’re staying on the right track.
