Abstract:
Artificial insemination with donor sperm is a widely accepted form of treatment for severe male factor infertility. The introduction of quarantined, cryopreserved semen and the associated reduction in cycle fecundity when compared to fresh semen necessitated the development of strategies to improve the performance of frozen sperm. A prospective randomised clinical trail was undertaken in the Reproductive Medicine Unit at Groote Schuur Hospital to compare intrauterine insemination with intracervical insemination in a therapeutic donor insemination program with cryopreserved semen.

Abstract:
A theoretical study showed that Al can greatly affect the efficiency of sheep breeding schemes provided fertility is maintained at the highest levels. Factors that affect the survival of ram spermatozoa during preservation were studied. A pH range between 6 and 7 was well tolerated. The addition of 4% (v/v) glycerol to the diluted ram semen in Tris buffer lowered the motility and survival of spermatozoa during 5 hours of storage at 30'C. Following insemination of chilled ram semen, with and without glycerol in the diluent, lambing percentages of 59% and 73% respectively were obtained. Ram seme

Abstract:
In the last 50 years, milk production increased in lactating dairy cows. In contrast, reproductive efficiency has dramatically decreased. Several causes may be involved, such as management and environmental factors, physiological and nutritional factors, disease challenges and others. Steroid hormone concentrations in high-producing lactating dairy cows are often at lower levels, due to high dry matter intake and increased liver blood flow and steroid hormones metabolism, which is associated with the compromised estrus expression and reduced oocyte quality, thus decreasing fertility. However,

Abstract:
Embryo transfer plays a very important role in the cattle industry and its application requires a consistent supply of viable embryos for use in such programmes. One way of achieving this is the development of reliable superovulation regimens, yielding a large number of high quality embryos. Superovulation with pregnant mare serum gonadotrophin (PMSG) induces a second wave of follicles after ovulation because it is eliminated slowly from the peripheral blood, causing high concentrations of oestradiol. This oestradiol may have an adverse effect on fertilization and early embryonic development.

A aspiração de folículos ≥25mm promove a formação de uma estrutura lútea capaz de produzir progesterona em concentrações semelhantes ao diestro (>2ng/ml). O objetivo do presente trabalho foi avaliar a formação lútea de folículos ≥25mm aspirados, o útero e a taxa de prenhez destes
