Does timed intercourse work if I have Polycystic Ovary Syndrome (PCOS)?

Yes, for certain types of PCOS this treatment can be effective. It helps the ovaries release an egg on time, correcting the typical irregularity of Polycystic Ovary Syndrome through controlled ovarian stimulation.

When is the exact right time to have intercourse during timed intercourse?

After the trigger injection, ovulation occurs approximately 36 hours later. The ideal approach is to have intercourse that day and the following two days to maximize the chances of the sperm meeting the egg.

Is there a risk of multiple pregnancy with timed intercourse?

There is a 10-15% chance of a twin pregnancy, as ovarian stimulation medication can cause more than one egg to mature in the same cycle. This risk is monitored via ultrasound during follow-up.

How many timed intercourse cycles are recommended before moving to another treatment?

A maximum of 3 cycles is recommended. If pregnancy is not achieved within that timeframe, the most appropriate step is to progress to a treatment with higher success rates, such as intrauterine insemination (IUI) or in vitro fertilization (IVF), depending on the diagnosis.

Does age affect the effectiveness of timed intercourse?

Yes, it is most effective in women under 35. Over time, egg quality and quantity decline, and it is usually more advisable to consider options with higher success rates to avoid losing valuable time on the reproductive journey.

Timed Intercourse in Mexico: A Clear Guide to Getting Pregnant

Q: What is timed intercourse?

It is a low-complexity fertility treatment that synchronizes sexual intercourse with ovulation through medical monitoring using ultrasound. Unlike insemination, there are no catheters or laboratory intervention; fertilization occurs naturally.

Q: How much does timed intercourse cost in Mexico?

The medical package is approximately $19,000 MXN at Avida Fertility. Additional medication costs vary based on the initial evaluation and each patient's needs. The final budget is determined after a personalized medical assessment.

Q: How effective is timed intercourse?

The probability of pregnancy is 5% to 10% per cycle. It is a scientifically supported approach to natural conception, but it does not guarantee immediate success. The probabilities are cumulative across multiple well-indicated cycles.

Timed intercourse is a fertility treatment that aims to synchronize the fertile window with sexual intercourse, with medical guidance when needed, to attempt pregnancy in a structured and natural way.

At Avida Fertility, we focus on precision and your peace of mind: we know that trying to calculate fertile days month after month with apps or home tests can become exhausting. That's why we leave assumptions behind. Through careful medical monitoring with ultrasound and hormonal analysis, we identify the exact moment of your ovulation to create a 100% personalized plan.

If you've been trying for months at home and feel that the journey has stopped being intimate and become a source of stress, we are here to give you back control. We offer you a clear diagnosis and a compassionate team that will closely support you in exploring whether this, or other fertility treatments, is the right path for your situation.

When is timed intercourse recommended?

Timed intercourse is often considered when there's a need to better understand the cycle and optimize the timing of ovulation, always after a medical evaluation. It's not a diagnosis itself, but rather a strategy that can be useful for certain profiles.
‍

Difficulty identifying ovulation or irregular cycles

When cycles are not predictable or there are doubts about when ovulation occurs, monitoring helps to more clearly pinpoint the fertile window.

Suspected infrequent ovulation

For individuals who may not ovulate every month, timed intercourse allows for cycle evaluation and helps determine if any medical support is needed.

First step before more complex techniques

In some cases, it is used as an initial step before considering more advanced treatments, always based on individual clinical evaluation.

Seeking a “naturally assisted” approach

For young couples or individuals who wish to attempt pregnancy with a structured plan and medical supervision, without yet moving on to laboratory techniques.

Difficulty identifying ovulation or irregular cycles

When cycles are not predictable or there are doubts about when ovulation occurs, monitoring helps to more clearly pinpoint the fertile window.

Do you identify with any of these scenarios? If your cycles are irregular, you have doubts about your ovulation, or you're looking for clear medical guidance to try with a structured approach, the most advisable thing is to schedule an evaluation and determine the best path for you.

If there are complex medical histories, signs of a severe factor, or a more challenging reproductive history, it's important to perform a comprehensive evaluation and discuss other alternatives with the specialist, such as artificial insemination (IUI) or in vitro fertilization (IVF), without jumping to conclusions prematurely.

How timed intercourse works step-by-step (with and without stimulation)

From your initial consultation to preservation, every stage of your journey is designed to give you peace of mind and confidence. The goal is to precisely identify ovulation and guide the timing of intercourse, with or without medical support, based on your profile.

The process is clear, gradual, and always supervised.

Let's get started!

STEP 1

Initial evaluation

We perform complete semen analysis, sperm DNA fragmentation testing, and detailed morphological evaluation. Our AI system analyzes every parameter to define the best ICSI strategy.
‍
- Ultrasound, based on medical judgment
- Hormonal blood work in selected cases
- Semen analysis if applicable

STEP 2

Ovarian preparation and stimulation

Personalized stimulation protocol to retrieve the highest-quality eggs. Continuous monitoring with high-resolution ultrasound and hormonal analysis optimized by artificial intelligence.

- Urine-based LH testing
- TrRansvaginal ultrasound
- Hormonal blood work in specific situations

STEP 3

Timed intercourse without stimulation (natural cycle)

Once the cycle enters the ovulation phase, we identify the fertile window and guide the timing of intercourse. We don't adhere to rigid dates; the process is supported flexibly and personally.

STEP 4

Timed intercourse with stimulation: clomiphene citrate and alternatives

In selected cases, medications such as clomiphene citrate are used to induce or regulate ovulation or to support follicular development. Always under medical supervision, with clear explanations of benefits and potential side effects, without causing alarm.

STEP 5

After timed intercourse: follow-up

After the cycle, there is a waiting period. The team will advise when to take a pregnancy test and how the follow-up will proceed, avoiding hasty decisions.

How much does timed intercourse cost in Mexico?

We understand that every person is unique. That's why we offer personalized fertility tests that go beyond a simple diagnosis. Our team of specialists guides you every step of the way, helping you find the most suitable path for your family. The estimated cost of a timed intercourse cycle in Mexico ranges between $8,000 and $18,000 MXN.

This average range generally covers medical consultations and follicular monitoring via ultrasound to track your ovulation.However, at Avida Fertility we prioritize transparency: the cost of timed intercourse isn't fixed because it depends entirely on what your body needs. Not every patient requires the same level of monitoring or the same type of medication support.

Cycle monitoring

It may include ultrasound and ovulation tests

Medication Use

Only if ovulation induction or regulation is indicated

Prior Studies

Depending on each patient's hormonal response.

Therefore, the clearest and most honest way to discuss costs is through a medical evaluation, where exactly what you need and don't need is defined.‍

Timed Intercourse vs. IUI vs. IVF: How to Decide Your Next Step

Choosing between timed intercourse, intrauterine insemination (IUI), and in vitro fertilization (IVF) depends on your diagnosis, complexity, and reproductive goals. The guidelines from the American Society for Reproductive Medicine (ASRM) suggest an evidence-based, stepped approach for couples with unexplained infertility, considering methods from less invasive to more complex. ‍
