The impact of the occurrence of ovarian focular dominance during hormonal stimulation for maturation in vitro is analyzed. This retrospective cohort study included 21 patients with polycystic ovaries or polycystic ovary syndrome (Rotterdam criteria, 2004) who underwent 24 cycles of in vitro maturation (IVM) between October 2015 and January 2017.

Objective: To establish the prevalence of Chlamydia trachomatis infection in a population with reproductive problems. Design: Descriptive epidemiological study performed between july 1997 and june 1998. Material: To 140 couples with problems of reproduction attended at the Human Reproduction Unit of EsSalud Edgardo Rebagliati Martins National Hospital endocervical (women) or urethral (men) samples were obtained to detect Chlamydia trachomatis. Study measures: Detection of C. trachomatis by direct immunofluorescence, IgG and ’IgA. Results: By direct immunofluorescence Chlamydia antigen was present in 122(43,6%) patients, in both members of the couple in 59,8%. The majority of patients did not present symptoms, 23% did not have sperm alteration, notwithstanding being Chlamydia positive and the majority of women showed tubal alterations by laparoscopy and 12% microvesicles. Conclusion: Pr...
