“…Previously, in 1913, Hüner explained how changes in cervical mucus allow the sperm to permeate (37). Odeblad, in 1966, began to describe the different crystal patterns of cervical mucus, initially classifying them into two types: Type E secre tion, which is predominantly estrogenic, and Type G secre tion, which is gestagenic and segregated during the luteal phase (38, 39, and 40).…”

resumen El objetivo de este artículo es revisar los principales conceptos en la literatura acerca de la ventana de la fertilidad en pacientes con ciclos menstruales normales. Los conceptos básicos de la ovulación han sido revisados. El énfasis principal del artículo se ha dirigido al análisis de la teoría de Brown de la ovulación, revisar los conceptos básicos de la secreción y metabolismo de la hormona folículo estimulante, y al estudio clínico, ecográfico y bioquímicos del desarrollo folicular la ventana de la fertilidad. Este artículo también repasa los biomarcadores clínicos y los diferentes metabolitos endocrinos que han sido probados en la fase fértil del ciclo. Se revisan diferentes estudios en los cuales las valoraciones en suero y orina de los esteroides sexuales han corroborado tener una correlación directa para enmarcar el período fértil. Actualmente tienen relevancia estos conocimientos en diferentes grupos de interés, sobre todo en parejas con un alto nivel de motivación en el reconocimiento de la fertilidad, y que pueden beneficiarse mediante la aplicación de los conocimientos técnicos actuales en la detección de la ventana de la fertilidad. Otro tipo de parejas suelen ser aquellas que pertene- cen a programas de regulación de la fertilidad (PRF) con intención de distanciar un embarazo, así como también de reconocer la época más fértil del ciclo para conseguir un embarazo. Otros interesados suelen ser personas que no tienen experiencia en cursos de PRF, pero desean mejorar su conocimiento en el reconocimiento de la fertilidad por medio de una breve entrevista, o parejas que buscan opciones de un embarazo mediante programas de NaProTecnología o que han realizado cursos de orientación familiar.

“…Early in the beginning of the twenty century it is failed to find sperms in a post coital test. [1] This finding raised the possibility that husband could be responsible for infertility. The available statistics showed that the male factor is responsible for about 40% to 50% of all cases of sterility.…”

Background: Aims: The objective of this study was to assess the diagnostic accuracy and cytological features of fine needle aspiration cytology smears (FNAC) in determining the causes of azoospermia as compared to open testicular biopsy. Methods: 35 patients with non-obstructive azoospermia were subjected to the study; the age of them was 20-40 years. Each patient was subjected to the taking history and clinical examination. Laboratory tests were done including urine analysis, three consecutive semen samples and endocrine evaluation. Then, cord block was achieved with 1% lignocaine; and fine needle aspiration was be done, then staining the smears with Leishman or hematoxylene and eosin stains. In the same sitting, testicular biopsy was taken, then Hematoxylin & Eosin (H&E)-stained sections were prepared. Histopathological and cytological evaluation was investigated; and photographs were be taken. Then, statistical analysis was performed. Results: The concordance of FNAC with open biopsy in the diagnosis of azoospermia was 100%. FNAC smears was associated with fewer complications such as bleeding, pain and hematoma than in case of open biopsy. Conclusion:The technique of testicular FNAC is simple, more than one specimen could be taken safely. FNAC is representative and correlates well with testicular biopsy histology.
