Sperm-mediated gene transfer (SMGT) is a simple, fast, and economical biotechnological tool for producing transgenic animals. However, transgene expression with this technique in bovine embryos is still inefficient due to low uptake and binding of exogenous DNA in spermatozoa. The present study evaluated the effects of sperm membrane destabilization on the binding capacity, location and quantity of bound exogenous DNA in cryopreserved bovine spermatozoa using Triton X-100 (TX-100), lysolecithin (LL) and sodium hydroxide (NaOH)...

PURPOSE: Partial thawing of a vial of cryopreserved sperm (shaving) is sometimes applied as a measure to preserve sperm for further use, particularly in cases of very restricted sperm quantity. However, mechanical violence may disrupt the sperm-wall and lead to impaired in-vitro fertilization (IVF) outcomes. MATERIAL AND METHODS: In a retrospective case-control study at a tertiary, university-affiliated medical center, we compared the IVF/intracytoplasmic sperm injection (ICSI) outcomes of patients who used donor sperm following partial thawing (shaving) of the vial of cryopreserved sperm (n = 99) to a control group consisting of patients for whom the vial of sperm was completely thawed before use (n = 99)...

BACKGROUND: The mechanism of intramanchette transport is crucial to the transformation of sperm tail and the nuclear condensation during spermiogenesis. Although few dysfunctional proteins could result in abnormal junction between the head and tail of spermatozoon, little is known about the genetic cues in this process. OBJECTIVE: Based on patients with severe decapitated and decaudated spermatozoa (DDS) syndrome, the study aimed to validate whether new mutation exists on their Hook microtubule-tethering protein 1 (HOOK1) genes and follow their results of assisted reproduction treatment (ART)...

Embryo micromanipulation was developed after introduction of microinjection to overcome infertility. Embryo micromanipulation may be performed at any embryo stage from pronuclear to blastocyst. The technique started out as basic and turned out to be increasingly more complex. Embryo micromanipulation at the cleavage-stage includes a wide range of techniques, from opening the zona pellucida in order to improve the chance of implantation, to removing detrimental components from the embryo to enhance embryo development or blastomeres for preimplantation genetic diagnosis and embryo splitting...

Intracytoplasmic sperm injection (ICSI) is the injection of a single spermatozoon directly into the cytoplasm of an oocyte using an injection pipette. Spermatozoa that are used for ICSI do not need to be motile or alive. Indeed, for mouse ICSI, the sperm tail is typically broken off before injection into the oocyte, resulting essentially in a nuclear transfer. The protocol describes creation of the injection pipettes, preparation of oocytes and spermatozoa, and steps of the ICSI procedure. The technique can be used to create both hybrid and inbred mice, as well as transgenic animals...

Aim: To determine whether there are differences in size between the male and female pronuclei immediately before the pronuclear membrane breakdown (PNMBD) and to evaluate whether pronuclear size differences influence normal birth rates. Methods: Time-lapse photography was used to measure the size of each pronucleus, while the outcome of 71 frozen-thawed single blastocyst transfers in patients receiving hormone therapy was analyzed retrospectively. The pronuclear measurements were made 4 hours before the PNMBD, corresponding to 16-20 hours after insemination or intracytoplasmic sperm injection, and immediately before the PNMBD...

Previous studies have suggested an association between high intake of sweetened beverages and a number of adverse health outcomes. In this cross-sectional study, we investigated the association between daily consumption of sweetened soft drinks or coffee and the outcome of intracytoplasmic sperm injection (ICSI) treatment. Patients (n = 524) were interviewed by a nutritionist before ICSI treatment, using a food frequency questionnaire. Regression analysis showed that consumption of ≥3 servings of regular soft drinks or any amount of diet soft drinks was associated with oocyte dysmorphism, diminished embryo quality on days 2 and 3 of culture, and a mild effect on blastocyst formation, implantation and pregnancy rate...
