background: testis tissue xenografting and the resultant sperm in a xenograft may provide a unique approach to rescue the genetic material of males that die prematurely and is a model for the study of human spermatogenesis and can represent an alternative approach for fertility preservation in cancer patients. this study was aimed to evaluate the xenogenic dog sperm in formation of male pronucl...

the purpose of this study was to evaluate the efficiency of intracytoplasmic sperm injection (icsi) and piezo-assisted sperm injection after pretreatment with calcium ionophore (cai) on the mouse embryo development. methods: in this study, the conventional icsi and piezo-icsi procedures were used. the efficacy of the methods was examined after mouse matured oocytes were fertilized with or witho...

Aim: This study aimed to investigate the effect of luteal phase support (LPS) with estradiol in addition progesterone on pregnancy outcomes patients who underwent ovulation induction GnRH antagonist protocol vitro fertilization- intracytoplasmic sperm injection (IVF-ICSI).
 Materials and Methods: retrospective was carried out at reproductive medicine center Necmettin Erbakan University Mer...

OBJECTIVE The objective of the present study was to evaluate the correlation between anti-müllerian hormone (AMH), inhibin B, and activin A in follicular fluid from patients receiving treatment with in-vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI), to identify a parameter to assess the maturation and developmental potential of oocytes. - MATERIALS AND METHODS AMH, inhi...

Background The purpose of this prospective randomized study was to compare ovarian response as well as oocytes embryo yields and pregnancy rates in women who underwent ovulation induction for intracytoplasmic sperm injection (ICSI) with recombinant human FSH (rFSH) alone or in combination with human menopausal gonadotropin (HMG). MaterialsAndMethods Out of 300 patients in assisted reproductive ...

Serum follicle stimulating hormone (FSH) is routinely measured when evaluating the infertile male for intracytoplasmic sperm injection (ICSI). However, among the sperm parameters, only its relationship with sperm concentration is well documented. Few investigations concern the relationship between FSH and sperm motility and morphology, and the results of ICSI. A retrospective study of 316 coupl...

IVF has become a well-established treatment for certain types of infertility, including long-standing infertility due to tubal disease, endometriosis, unexplained infertility or infertility involving a male factor. Soon it became clear that certain couples with severe male-factor infertility could not be helped by conventional IVF. Extremely low sperm counts, impaired motility and/or abnormal m...

OBJECTIVE To examine the effect of sperm morphology on embryo development at the chromosomal level. DESIGN Prospective study. SETTING Assisted fertilization center. PATIENT(S) Couples who underwent IVF-PGS cycle, as a result of advanced maternal age, were randomly allocated into two groups: intracytoplasmic sperm injection (ICSI; n = 60) or intracytoplasmic morphologically selected sperm ...
