Fluid buildup after egg retrieval usually requires no treatment if the fluid is small and there are no uncomfortable symptoms; if the fluid is large, treatment is required as prescribed by your doctor. If a pelvic effusion tends to form after egg retrieval, mainly because after each follicle is punctured, a considerable amount of follicular fluid will flow into the uterorectal trap, an effusion will form. This kind of effusion does not need to be eliminated with drugs deliberately in the clinic, and tends to be absorbed slowly on its own, and the vast majority of them will be absorbed on their own in about half a month or so. A small number of patients may cause follicular overstimulation after egg retrieval, resulting in a large amount of pelvic fluid accumulation and ascites, which is clinically necessary to be hospitalized for rehydration and symptomatic treatment. Otherwise, if a large amount of ascites in the clinical often lead to patients with electrolyte disorders, resulting in serious consequences. After taking eggs with fluid, it is recommended that patients go to the hospital, under the guidance of the doctor to determine clearly, according to the actual situation of the choice of treatment plan, to avoid delaying the condition of the adverse consequences.
