Impact of donor mare and stallion identity on the likelihood of pregnancy after transfer of in vitro produced embryos

Equine Veterinary Journal, EarlyView.
Abstract Background The success of in vitro embryo production (IVEP) is influenced by donor mare and stallion. Objectives To determine whether donor mare and stallion influence the pregnancy rate after transfer of in vitro produced (IVP) blastocysts and to identify factors influencing the likelihood of obtaining one or more pregnancies from a single ...

Comparison of intracytoplasmic sperm injection outcomes in men with spinal cord injury using sperm retrieved by electroejaculation and testicular sperm extraction methods: A retrospective cohort study

International Journal of Reproductive BioMedicine
Background: Individuals with spinal cord injury (SCI) face fertility concerns due to various causes, such as low sperm quality and ejaculatory dysfunction. Consequently, different sperm retrieval techniques are used for these cases, including testicular

Age, embryo donor status, and insemination with chilled semen all predispose to persistent breeding‐induced endometritis in warmblood mares

Equine Veterinary Journal, EarlyView.
Abstract Background Persistent breeding‐induced endometritis (PBIE) is a common reason for mares failing to establish pregnancy. Objective To examine the hypothesis that advancing mare age and embryo donor status predispose to PBIE and compromise fertility.

Role of testicular fine‐needle aspiration in the modern male reproductive urologist′s practice

UroPrecision, EarlyView.
Abstract Background Azoospermia affects 10%–15% of infertile men, with non‐obstructive azoospermia (NOA) most often managed by microdissection testicular sperm extraction (mTESE). Despite AUA/ASRM guidelines recommending mTESE, some urologists employ testicular fine‐needle aspiration (TFNA) mapping as a diagnostic adjunct.

Influence of female age on blastulation rate of embryo produced by ICSI [PDF]

Einstein (São Paulo), 2003
OBJECTIVES: There is a tendency to adopt prolonged culture inolder patients; however there are no conclusive results about theinfluence of age on blastulation rate. Therefore, we decided to analyzethe influence of female age on prolonged culture results.

Micro-dissection testicular sperm extraction as an alternative for sperm acquisition in the most difficult cases of Azoospermia: Technique and preliminary results in India

Journal of Human Reproductive Sciences, 2013
Context: Non-obstructive azoospermia (NOA) is an unfavorable prognostic condition for male infertility since spermatogenesis is disrupted. Sperm retrieval (SR) coupled with intracytoplasmic sperm injection (ICSI) is the only option for men with NOA who ...

Microfluidic Intracytoplasmic Sperm Injection (MICSI): A Novel Platform for Sperm Isolation, Selection, and Injection Into Oocytes

Andrology, EarlyView.
ABSTRACT Background Infertility is a pressing global health concern, affecting one in six couples worldwide. The failure rate for assisted reproductive technologies (ART) cycles remains at approximately 78%, with limited improvements often attributed to a lack of technological innovation.

Hyaluronan Sperm Selection during ICSI (HA-ICSI) Increases Embryo Utilization in Couples with Male Factor Infertility

Fertility & Reproduction
Background: Hyaluronan (HA) sperm selection, utilizing the affinity of mature sperm for HA, has emerged as a technique to enhance the selection of sperm for intracytoplasmic sperm injection (ICSI).

Sperm retrieval techniques in azoospermic patients: PESA, MESA, TESA, TESE and MICROTESE [PDF]

Einstein (São Paulo), 2009
Azoospermia is defined as the absence of mature spermatozoa in semen analysis after centrifugation. The causes of azoospermia may be related to spermatogenesis defects and classified as non-obstructive azoospermia, or to the obstruction of the efferent ...
