Houston COS

COS is a fertility treatment using hormone injections called gonadotropins to help the ovaries produce multiple mature eggs in one cycle. This increases the number of eggs available for IUI or IVF and supports better timing and treatment outcomes.

Gonadotropins directly stimulate the ovaries, allowing more follicles to grow than in a natural cycle. This provides more opportunities for fertilization and helps physicians monitor and adjust treatment based on your individual response.

A typical COS cycle lasts 10–14 days. During this time, you take daily hormone injections and attend monitoring appointments. Once follicles reach the right size, a trigger shot prepares the eggs for retrieval or timed insemination.

Patients usually have several ultrasounds and blood tests throughout COS. Monitoring ensures that follicles grow safely and appropriately, allowing your physician to adjust medication doses and reduce the risk of overstimulation.

Yes. COS supports IUI by helping develop more mature eggs, and it is essential for IVF, where multiple eggs are needed for retrieval. Your physician will determine how COS fits into your specific treatment plan.

COS can increase the likelihood of twins or higher-order multiples because multiple follicles may mature. Monitoring and careful dose adjustments help manage this risk and support safe, appropriate follicle development.

Most patients find the injections manageable after instruction. The needles are small, and our team provides guidance and demonstrations. Many patients feel more comfortable after the first few doses.

Some patients experience bloating, mild discomfort, or temporary mood changes due to hormone stimulation. These symptoms typically resolve quickly after the cycle ends and are monitored throughout treatment.

OHSS is a rare but possible reaction to stimulation medications, causing bloating or abdominal discomfort. Close monitoring, dose adjustments, and careful cycle management significantly reduce the risk.

After COS, the next step depends on your treatment plan. You may proceed to IUI, undergo egg retrieval for IVF, or evaluate your response to prepare for future cycles. Your physician will explain the next steps based on your results.
