Female infertility becomes most common as women age, with fertility gradually declining in the early 30s, then rapidly accelerating after age 35, and especially after age 40, due to fewer and lower-quality eggs, though some decline starts around age 32. While the "biological clock" is a key factor, lifestyle, genetics, and conditions like PCOS also impact fertility.
If your menstrual cycle is regular, the least likely time to get pregnant is typically during your period, usually from day 1 to day 7. During this time, your body is shedding the uterine lining, making it harder for pregnancy to occur.
Infertility in women
Jennifer Aniston underwent IVF treatments throughout her late 30s and 40s, a challenging period where she tried everything to conceive, eventually continuing into her early 50s, ultimately deciding to share her private fertility struggle years later in an interview with Allure.
In Your 20s: The late teens through mid-20s are often considered a woman's most fertile years. During this period, the chances of conception per cycle are at their peak. A healthy woman in her early 20s might have roughly a 25% chance of getting pregnant in any given menstrual cycle.
The main symptom of infertility is the inability to get pregnant. A menstrual cycle that's too long (35 days or more), too short (less than 21 days), irregular or absent can mean that you're not ovulating. There might be no other signs or symptoms.
The "3 over 6 rule" in fertility awareness methods (FAMs) confirms ovulation by identifying a sustained rise in your Basal Body Temperature (BBT): it requires three consecutive days of temperatures higher than the six days before them, with the third high temperature being at least 0.2°C (0.4°F) above the preceding six days' highest point, marking the end of the fertile window for avoiding pregnancy and confirming ovulation has occurred. This rule, used with other signs like cervical mucus, helps pinpoint the infertile phase after ovulation, but it's not an exact science and requires careful daily tracking.
The actress and singer made the admission in a candid interview with US magazine People. Jennifer told the magazine: "It was natural. We didn't do in vitro. Everyone assumed that, because we had twins."
Jennifer Aniston's 80/20 rule is a balanced approach to wellness, focusing on healthy, nutrient-dense foods 80% of the time while allowing for indulgences like pizza, pasta, or martinis (the 20%) without guilt, promoting consistency and sustainability over perfection. It's about moderation, enjoying life's treats, and getting back on track with healthy choices at the next meal or workout, emphasizing that no food is inherently "bad".
Actress Jennifer Aniston underwent multiple unsuccessful rounds of IVF (in vitro fertilization) during her journey to have children, revealing she tried for years, changed clinics, and experienced several failed cycles before stopping, but has expressed having "zero regrets" about her path. While the exact number isn't specified, she described it as a challenging, multi-year process involving numerous attempts.
Infertility in older women likely is due to the lower number and quality of eggs, or to health problems that affect fertility. Men over age 40 may be less fertile than younger men. The risk of birth defects and genetic problems also rises for children born to men over age 40.

7 signs of ovulation
If you want to work out when you ovulate, there are several things you can try, such as monitoring your cervical mucus changes and body temperature or using ovulation test kits. Understanding these body signs can be a way of knowing your fertile days. Read more about the menstrual cycle and getting pregnant.
You cannot see or feel these changes, and they happen faster than you may think. A woman's peak reproductive years are between the late teens and late 20s. By age 30, fertility (the ability to get pregnant) starts to decline. This decline happens faster once you reach your mid-30s.
To protect your fertility, make these healthy lifestyle choices:
It's tied to her birthday (February 11), but it's also a spiritual number often associated with synchronicity, intuition, and alignment — a reminder to trust the universe's timing. It's also believed to be a tribute to her late dog, Norman, whom she adored and often spoke about with great affection.
Actress Jennifer Aniston has publicly shared that she was diagnosed with dyslexia in her 20s, a diagnosis that explained lifelong struggles with reading, writing, and retaining information, leading her to believe she wasn't smart until discovering the learning disorder. She discovered this during an eye exam, where she realized her eyes jumped words when reading, and the diagnosis helped her understand past difficulties, transforming her self-perception.
At a reported 5' 5” inches, weighing 110 pounds would give Aniston a BMI of 18.5, just barely in the normal weight range.
Most recently, former first lady Michelle Obama opened up about her own struggles with infertility, and undergoing in vitro fertilization (IVF) treatments to conceive her daughters Malia and Sasha. She is one of the millions of American women who have undergone IVF treatments to start and expand their families.

True, for parents with many children, the birth of twins was not a surprise. Jolie also resorted to IVF and assumed that she would become a mother of twins.

Four common signs of ovulation are changes in cervical mucus (becoming clear, stretchy, like egg whites), mild lower abdominal pain or cramping (mittelschmerz), a slight increase in basal body temperature, and an increased libido or sex drive, though not everyone experiences all these signs. Other indicators can include breast tenderness, bloating, light spotting, or mood changes, as hormonal shifts prepare the body for a potential pregnancy.
It's All About Ovulation
Your peak days for fertility are the day of ovulation and the five days right before you ovulate. For the average woman, these are days 10 to 17 of her 28-day cycle, with day 1 being the day your period starts.
Basal body temperature may increase slightly — typically less than a 1/2 degree F (0.3 C) — when you ovulate. Ovulation has likely occurred when the slightly higher temperature remains steady for three days or more. Plan sex carefully during fertile days.
