1. Efeito da adição de plasma seminal oriundo de animais de alta e baixa fertilidade na criopreservação de espermatozoides da cauda do epidídimo e do ejaculado de garanhões subférteis
RESUMO O objetivo do presente estudo foi avaliar o efeito da adição de plasma seminal de garanhões de alta e baixa fertilidade sobre a congelabilidade e a viabilidade de espermatozoides do ejaculado (EJ) e do epidídimo (EP) de garanhões subférteis. Foram utilizados seis garanhões com histórico de subfertilidade. Após coleta, espermatozoides do ejacu

2. Pregnancy and birth after intracytoplasmic sperm injection with normal testicular spermatozoa in a patient with azoospermia and tail stump epididymal sperm
Main findings: An intriguing yet perplexing case report of a successful pregnancy and live birth with intracytoplasmic sperm injection using normal testicular sperm, after the finding of azoospermia in the semen analysis and discovering only tail stump abnormal sperm in the epididymis. Case hypothesis: A tail stump sperm defect of genetic origin was suspec

3. Percutaneous epididymal sperm aspiration as a method for sperm retrieval in men with obstructive azoospermia seeking fertility: operative and laboratory aspects
ABSTRACTIntroduction:Congenital bilateral absence of vas deferens (CBAVD) is a non-treatable cause of obstructive azoospermia (OA). However, the affected men can father children by undergoing sperm retrieval (SR) and intracytoplasmic sperm injection (ICSI).Materials and Methods:This video describes percutaneous epididymal sperm aspiration (PESA), performed o

4. Histomorphological changes by epididymal lithiasis in roosters
Epididymal lithiasis (EL) histopathology is described using light and electronic microscopy in roosters (Gallus gallus domesticus) naturally affected by EL in Minas Gerais, Brazil. The histologic and morphological changes by EL in roosters was performed regarding cellular and subcellular details through light and electron microscopy. Efferent ductules epithe

5. Viability of bull spermatozoa collected from the epididymis stored at 18-20°C
The aim of this study was to evaluate the viability of bull spermatozoa collected from the cauda epididymis stored at 18-20°C, which were compared with semen collected by electro-ejaculation method and preserved at 5°C. Ten pairs of testes from Tabapuã bulls were removed by orchiectomy and stored for 6 (G6), 12 (G12), 18 (G18), 24 (G24) and 30 (G30) h at

6. Sperm analysis of the vas deferens fluid after a long interval of unilateral percutaneous epididymal sperm aspiration in vasectomized patients
Objectives Evaluation of the presence of spermatozoa in vas deferens fluid after a long interval of unilateral and homolateral percutaneous epididymal sperm aspiration (PESA) in vasectomized men. When found, the spermatozoa were evaluated including concentration and motility, in order to verify the patency of the epididymal tubules. Materials and Methods F

7. Cryopreservation of testicular and epididymal sperm: techniques and clinical outcomes of assisted conception
The introduction of the technique of intracytoplasmic sperm injection to achieve fertilization, especially using surgically retrieved testicular or epididymal sperm from men with obstructive or non-obstructive azoospermia, has revolutionized the field of assisted reproduction. The techniques for the retrieval of spermatozoa vary from relatively simple percut

8. Laboratory processing and intracytoplasmic sperm injection using epididymal and testicular spermatozoa: what can be done to improve outcomes?
There are two main reasons why sperm may be absent from semen. Obstructive azoospermia is the result of a blockage in the male reproductive tract; in this case, sperm are produced in the testicle but are trapped in the epididymis. Non-obstructive azoospermia is the result of severely impaired or non-existent sperm production. There are three different sperm-

9. Sperm retrieval techniques for assisted reproduction
Different surgical methods such as PESA, MESA, TESA, TESE and micro-TESE have been developed to retrieve spermatozoa from either the epididymis or the testis according to the type of azoospermia, i.e., obstructive or non-obstructive. Laboratory techniques are used to remove contaminants, cellular debris, and red blood cells following collection of the epidid

10. Restrição protéica in utero : desenvolvimento sexual e histofisiologia do sistema reprodutivo de ratos machos / In utero protein restrition : sexual development and histophysiology of the rat male reproductive tract
In the past few years the worldwide recognition of the relevance of nutrition as a basis for social and economic development has been growing. In developing countries such as Brazil undernutrition is a socioeconomic problem caused by poor nutrition and low income. The birth of children with low birth weight is considered an important public health problem, w

12. Epididymal lithiasis in Gallus gallus domesticus
A study on the occurrence of epididymal lithiasis (EL) in Gallus gallus domesticus of different breeds and from different geographical regions of Brazil was carried out. Forty breeding roosters were collected in the states Santa Catarina, São Paulo, Minas Gerais, Espírito Santo and Goiás, representing two specific pathogen free Leghorn lines (SPF), one co
