Pain and ovarian endometrioma recurrence after laparoscopic treatment of endometriosis: a long-term prospective study.
To identify prognostic factors for pain and endometrioma recurrence after complete laparoscopic excision of endometrioma(s). ⋯ Prior surgery, presence of adhesions, and ovulation drugs are negative prognostic factors. Pregnancy has a protective effect on disease and pain recurrence.

Racial and ethnic disparities in assisted reproductive technology outcomes in the United States.
To evaluate ethnic differences in assisted reproductive technology (ART) outcomes in the United States. ⋯ There are significant disparities in ART outcomes according to ethnicity.

To examine trends in use of medical services for infertility, by individual characteristics of women. ⋯ Infertility service use among fertility-impaired women remains closely tied with socioeconomic factors. The "threshold effect" of these factors has shifted upward to the receipt of more costly services such as assisted reproductive technologies. These higher level services remain a relatively small fraction of the services reported in a general population sample of fertility-impaired women.

Delivery rate using cryopreserved oocytes is comparable to conventional in vitro fertilization using fresh oocytes: potential fertility preservation for female cancer patients.
To explore the use of oocyte cryopreservation as a fertility-conserving option. Cancer treatments administered during the reproductive and adolescent years can result in sterility. Previous fertility preservation efforts focused on embryo rather than oocyte storage because the latter was deemed inefficient. Recently, several large reports of healthy births resulting from the transfer of embryos derived from frozen/thawed oocytes have been published. We sought to establish an oocyte cryopreservation program at our center. ⋯ Oocyte cryopreservation appears to be a viable option for fertility preservation in some centers.

Comparative StudySimilar ongoing pregnancy rates after blastocyst transfer in fresh donor cycles and autologous cycles using cryopreserved bipronuclear oocytes suggest similar viability of transferred blastocysts.
This retrospective cohort study compared blastocyst transfers in 136 fresh oocyte donor cycles and 69 autologous cycles using blastocysts derived from culture of thawed bipronuclear oocytes, all with oocytes derived from patients or donors less than 35 years old. The autologous cycles and oocyte donor cycles had similar rates of implantation (65.9% vs. 62.1%, respectively) and ongoing pregnancy (79.7% vs. 75.0%, respectively), suggesting that autologous blastocysts transferred after post-thaw extended culture have viability and implantation potential that are comparable with those of blastocysts transferred in fresh oocyte donor cycles.
