In a high-pressure, fast-paced lifestyle, coffee and alcohol have become daily staples for many people. However, when fertility becomes part of the plan—especially when entering a Mexico surrogacy process—these seemingly ordinary habits begin to have a more direct connection with outcomes.

Female Preparation Before Ovarian Stimulation: Hormonal Stability Comes First

Before entering an ovarian stimulation cycle, the primary goal for the female body is to establish a stable endocrine environment. Excessive caffeine intake may affect cortisol levels, indirectly interfering with how the ovaries respond to stimulation medications. Some individuals may experience asynchronous follicle development or fluctuating sensitivity to medications.

Alcohol has a more direct impact. It can disrupt the metabolism of estrogen and progesterone while increasing oxidative stress levels. These changes may not present immediate symptoms, but during stimulation, they can manifest as instability in egg quality.

Male Preparation Before Sperm Collection: The Timing of Sperm Quality

The male factor is often underestimated in fertility planning, yet sperm production is a continuous process lasting approximately 70–90 days. This means lifestyle changes do not produce immediate results but require early adjustment.

Caffeine has a relatively mild effect on sperm, but high intake may be associated with reduced motility. Alcohol, on the other hand, can more easily affect testosterone levels, thereby influencing sperm production quality, including count, motility, and DNA integrity.

Before entering the sperm collection stage, to achieve more stable sample quality, it is generally recommended to limit alcohol consumption and keep caffeine intake at a lower level for 2–3 months in advance.

Gestational Carrier Stage: Managing the Implantation Environment

In a Mexico surrogacy process, the gestational carrier’s physical condition also affects the final outcome. After embryo transfer, the uterine environment needs to remain stable, and both caffeine and alcohol may interfere with this process.

Caffeine may influence uterine blood flow, while alcohol can disrupt the microenvironment required for early embryo implantation. Therefore, before and after embryo transfer, strict limitation or complete avoidance is typically recommended. By adjusting these details and relying on Power Fertility Clinic to structure the process, each stage becomes more controlled, allowing intended parents to feel more at ease.
