This study compared the field fertility outcomes in frozen-thawed (FT) sperm from boar ejaculates with different freezability (good, GFE/poor, PFE) while testing the reliability of the post-cervical artificial insemination (post-CAI) in FT sperm. The assay was conducted over eight months with 86 weaned sows being inseminated by post-CAI. Every ejaculate in a total of 26 from 15 Piétrain boars w...

In the present study the Authors developed a new modified boar semen extender for short-term liquid storage, based on the use of amikacin sulphate and fructose rather than gentamicin and glucose. The new extender (ME-S) was evaluated and compared in vitro to commercial ones (CRONOS, TRIXcell) and to a modified extender designated for long term storage (ME-L) for progressive motility. Progressiv...

Little is known regarding the factors that influence reproduction in reindeer or of their reproductive physiology. Studies carried out to date have mainly focused on issues related to the populati...

In the last century, agriculture has seen the introduction of innovating reproductive biotechnologies that have permitted this field to grow significantly. In the early 20th century, introduction of semen cryopreservation and artificial insemination has propelled animal agriculture worldwide with the possibility to import and export in a biosecure way genetics from different species. Then, with...

Background Infertility adversely affects quality of life (QoL). The present study aims to evaluate QoL and its associated factors among infertile couples. MATERIALS AND METHODS In this cross-sectional study, the Fertility QoL (FertiQoL) instrument was used to measure QoL among 501 volunteer couples who attended the Infertility Clinic at the Mother and Child Hospital, Shiraz, Iran. We used an ...

BACKGROUND To examine whether pregnancy rate (PR) of intrauterine insemination (IUI) is related to certain demographic factors, such as age and body mass index (BMI), along with number of IUI cycles performed, a set of infertile Saudi women. MATERIALS AND METHODS During this prospective study (a 24-month period), 301 Saudi women with infertility underwent IUI in our infertility clinic. We inv...
