In this episode of The Diary Of A CEO podcast, Natalie Crawford, a pregnancy doctor, shares insights into increasing the chances of natural conception. She explains the fertile window and how cycle length determines its timing. Crawford also debunks common myths surrounding factors like sex positions and post-intercourse habits that are often mistakenly thought to impact fertility.
The discussion addresses the effect of age on female fertility, with Crawford noting a significant decline after 30. For couples facing challenges with regular intercourse, Crawford touches on alternatives like intrauterine insemination (IUI) and in vitro fertilization (IVF) to aid conception. The episode provides a practical understanding of the science behind pregnancy and conception.

Natalie Crawford shares that the fertile window spans the 5 days before ovulation and the day of ovulation. Since an egg survives for only 24 hours after ovulation and sperm can live in the female reproductive system up to 5 days, this window offers the highest chances of conception through intercourse.
Crawford explains cycle length determines when ovulation occurs and therefore the timing of the fertile window. She recommends having regular sex every day or every other day, rather than focusing solely on ovulation, to optimize chances of conception.
Crawford debunks several common fertility myths:
Crawford notes fertility significantly declines with age, especially after 30. For women under 30, the chance of pregnancy per month is about 20%. This drops to 10-15% by age 35, 5-8% by 38, and 3-5% by 40.
Steven Bartlett adds that waiting until later in life to start a family can increase pressure and negatively impact the enjoyment of sex due to meticulously timing intercourse for peak fertility.
For couples facing challenges with regular intercourse, Crawford discusses alternatives like intrauterine insemination (IUI) where sperm is injected directly into the uterus, bypassing the need for intercourse.
She also mentions in vitro fertilization (IVF) and other assisted reproductive technologies that help couples with fertility issues conceive and allow for embryo preservation for future family planning.
1-Page Summary
Understanding the timing of the fertile window, cycle length, and sexual frequency is critical for conception. Natalie Crawford shares insights on each of these elements.
Crawford explains that the fertile window encompasses not just the day of ovulation but also the five days leading up to it because the egg survives for only 24 hours after ovulation. Essentially, the egg needs to be fertilized within this narrow time frame to achieve conception. Additionally, since sperm can live in the female reproductive system for up to five days, intercourse during this window increases the chances of sperm meeting the egg.
The timing of ovulation is dependent on an individual’s menstrual cycle length. Crawford points out that in an average 28-day cycle, ovulation typically occurs on day 14. For a longer cycle, such as a 35-day cycle, ovulation is more likely to happen around day 21.
The science and biology of fertility and conception
In the journey to conceive, couples often encounter myths and misconceptions about what can improve their chances. Here, we address some common beliefs that have no impact on fertility.
Couples trying to conceive may hear advice about positioning hips after sex to increase the likelihood of pregnancy, but science says otherwise. Sperm are highly efficient swimmers that enter the fallopian tubes within minutes, so there's no need to prop hips up on a pillow or keep feet in the air.
Furthermore, urinating after intercourse won't flush sperm out because they enter the cervix within two minutes and can remain there for up to five days. While urination after sex isn't a contraceptive, it is recommended to help prevent urinary tract infections.
Another common myth is that certain sexual positions can improve the chances of conception or even influence the sex of the baby. However, the truth is that any position is suitable for conception as long as ejaculation occurs inside the vagina. The size of the penis or vagina does not affect sperm's ability to reach and ferti ...
Debunking myths and misconceptions around getting pregnant
Age is a critical factor when it comes to fertility, and understanding its impact is essential for those planning a family.
Fertility naturally declines as women age, with women under 30 having about a 20% chance of pregnancy per month. Natalie Crawford notes that this likelihood decreases with age, especially after 30. For women starting a family at 35, the chance of pregnancy per month is about 10 to 15 percent. By the time they reach 38, their chances dip to 5-8% per month. At age 40, the chances of getting pregnant drop further to 3-5% per month.

The Impact of Age on Fertility
Couples facing challenges with regular intercourse due to various circumstances have alternatives available for conception, such as intrauterine insemination (IUI) and in vitro fertilization (IVF).
Crawford discusses how IUI serves as a helpful method for couples where natural conception is problematic. She describes scenarios such as one partner having a career like a truck driver or pilot, which makes them absent during the fertile window, or cases where partners are high-performing individuals who may not prioritize or enjoy sexual intimacy.
She further explains the IUI procedure, where sperm are taken, processed, and then inserted directly into the uterus without the rest of the ejaculate. This part of the ejaculate typically serves to protect the sperm from the acidic environment of the vagina, but IUI bypasses this requirement by allowing the sperm to be placed directly where fertilization occurs.
