Becoming a mother at 50 after a tubal ligation may sound impossible, but today I share how, thanks to reproductive medicine and a team that supported me every step of the way, I fulfilled my dream. Here is my experience, my advice, and the science behind the entire process.
How was it possible to get pregnant at 50 after a tubal ligation?
Ligation prevents eggs from reaching the uterus but does not stop their production. Through ovarian puncture they are retrieved, fertilized in the lab, and then the embryo is transferred directly into the uterus, bypassing the tubes. This technique is called in vitro fertilization (IVF) and was the key in my case.
Hormonal and ovarian reserve tests
Before treatment, the following are measured:
- FSH and LH in blood (mIU/mL).
- AMH (anti-Müllerian hormone) in ng/mL.
- Antral follicle count via transvaginal ultrasound.
In my case, AMH was below 1 ng/mL, indicating low reserve, but with a personalized protocol I knew there was still a chance (I was 48 when I achieved it).
Recommended ovarian stimulation protocol
It is tailored to each woman but usually includes:
- Recombinant gonadotropins (150–300 IU/day).
- GnRH analogs to prevent spontaneous ovulation.
- Monitoring with ultrasound every 48 hours.
In my treatment I obtained four mature oocytes with moderate doses and careful monitoring.
Risks and prevention
The most common are:
- Ovarian hyperstimulation syndrome (OHSS).
- Multiple pregnancy.
- Age-related complications: hypertension, gestational diabetes.
To reduce them:
- Use low doses of gonadotropins.
- Monitor estradiol levels (pg/mL) frequently.
- Do not self-medicate without medical supervision.
Success rates with IVF at 50
With own eggs, rates range from 5% to 10%, but using donor eggs can exceed 50%. My case with own eggs was successful, inspired by stories like “I Did It Before 50”.
Care after embryo transfer
After the transfer:
- Relative rest for 24–48 hours.
- Progesterone (600 mg/day vaginally or 50 mg IM).
- Monitor symptoms: bloating, light bleeding.
Maintain a healthy lifestyle: balanced diet, avoid tobacco, and manage stress.
Frequently Asked Questions (FAQ)
Can I get pregnant naturally after tubal ligation?
The spontaneous probability is very low (<1%). Surgical reversal exists, but after 40, IVF is the best option to bypass the tubes and increase chances.
Is pregnancy at 50 safe?
Yes, with higher risks (hypertension, gestational diabetes, or growth restriction), but a multidisciplinary team (obstetrician, cardiologist, rheumatologist) can manage and monitor every stage.
How long does an IVF cycle last?
Between 4 and 6 weeks: initial evaluation, ovarian stimulation (10–14 days), retrieval, fertilization, and transfer. The timeline depends on response and possible cryopreservation.
What if my ovarian reserve is very low?
If AMH is <0.5 ng/mL and follicle count is low (<5), egg donation is an alternative that improves implantation rates and reduces failures.
