RESUMEN
Sperm morphology significantly influences the fertilization capacity of male germ cells. Morphological abnormalities are frequently associated with an overproduction of reactive oxygen species (ROS), leading to further sperm damage and subsequent infertility. This case study examines a couple facing infertility, with male factor infertility identified as the primary issue, characterized by teratozoospermia and a high DNA fragmentation index (DFI). The objective was to assess the efficacy of zeta potential (ZP) as a sperm sorting technique for intracytoplasmic sperm injection (ICSI) in patients showing high DNA fragmentation. A 34-year-old male with abnormal sperm parameters underwent ICSI using the ZP technique for sperm separation, while his 28-year-old female partner received ovarian stimulation. This intervention resulted in the development of two good-quality blastocysts, resulting in a successful embryo transfer (ET) and a positive pregnancy outcome. Previous attempts using conventional assisted reproductive technologies (ART), including in vitro fertilization (IVF), followed by ICSI and ET, as well as other sperm selection methods, were not successful. The ZP-based approach demonstrated significant benefits by selecting spermatozoa with optimal parameters, such as negative membrane potential, thereby enhancing the success rate. This case emphasizes the advantages of personalized treatment strategies in managing male infertility and highlights the potential of advanced sperm sorting techniques in improving fertility outcomes.
RESUMEN
Polycystic ovary syndrome (PCOS) is an endocrinological disorder affecting women of reproductive age, characterized by hormonal imbalance leading to metabolic and reproductive dysregulations. This case report revolves around a 30-year-old husband and his 27-year-old partner. The male partner had normozoospermia, and the female spouse had PCOS, according to the couple's diagnostic evaluations. The female patient received ovarian stimulation specifically to assist with PCOS, and the retrieved oocytes were then matured in vitro. After intracytoplasmic sperm injection (ICSI), fertilization and embryonic development were successful. Treatment of PCOS-related infertility presents many challenges, and in vitro maturation (IVM) and its potential as an effective assisted fertility method are discussed. To optimize treatment outcomes, the conclusion shows the importance of IVM and other assisted reproductive techniques for infertility. It also focuses on the necessary continuous research and clinical experience. Clinical pregnancy was confirmed by measuring serum beta-human chorionic gonadotropin (ß-hCG) levels followed by ultrasound sonography (USG), which showed a normal growth rate of the fetus.
RESUMEN
Low sperm count and motility in oligoasthenozoospermia present significant challenges to conception. This case report involves a couple, a 28-year-old female and a 35-year-old male, experiencing secondary infertility for four years. The male partner's habits of alcohol consumption and smoking were potential infertility factors. Semen analysis revealed a total sperm count of 10 million/mL, with total motility at 30% and progressive motility at 5%. The couple underwent intracytoplasmic sperm injection (ICSI), using advanced sperm separation techniques to isolate motile and morphologically normal sperm. Despite the suboptimal sperm parameters, this approach resulted in successful fertilization and pregnancy. The female partner's preparation involved a short antagonist treatment, leading to the retrieval of eight oocytes, seven of which were mature. A positive urine pregnancy test and ultrasound confirmed the pregnancy, with ß-hCG at 798 mIU/mL. This case highlights the potential of individualized treatments in managing oligoasthenozoospermia, emphasizing their promise in improving assisted reproductive outcomes despite mixed research results.
RESUMEN
Globozoospermia is a rare sperm morphological abnormality characterized by a lack of acrosomes and post-acrosomal sheaths, defects in the cytoskeleton around the nucleus, and separated nuclear membranes. In this case, the study outlines the treatment of a 32-year-old male patient diagnosed with globozoospermia. The couple, facing primary infertility for seven years, had already undergone unsuccessful assisted reproductive technology treatments, such as two intrauterine inseminations and one in vitro fertilization. They opted for intracytoplasmic sperm injection (ICSI) with assisted oocyte activation (AOA) using a calcium (Ca) ionophore. The semen analysis showed globozoospermia, which indicated that ICSI was required for fertilization. Post-fertilization, embryo quality was assessed; three were in cleavage-stage embryos, and two grade 4AA and 3AA blastocysts and the rest were arrested at 2 pronuclear (2PN) stages, revealing successful embryo development. This case report implies that using AOA with Ca ionophores enhanced the fertilization outcomes and could be a helpful intervention strategy for patients with globozoospermia.
RESUMEN
This case report describes the use of smooth endoplasmic reticulum aggregates-positive (SERa+) oocytes along with intracytoplasmic sperm injection (ICSI), supplemented with granulocyte-macrophage colony-stimulating factor (GM-CSF), aiming to enhance fertilization rates and reproductive outcomes. A 39-year-old woman, facing primary infertility for the past seven years, received assisted reproductive treatment (ART), which included adding GM-CSF to the culture medium and culture SERa+ oocytes before ICSI. Clinical results, embryo quality, fertilization rates, and other fertility parameters were used to track the patient's progress toward this individualized approach that led to a positive twin pregnancy and healthy twin babies.
RESUMEN
Infertility affects couples worldwide. Among these, obstructive azoospermia (OA) is a common cause. In some cases, the lack of spermatozoa in ejaculation results from blockages in the male reproductive tract. In this case study, we discuss an infertile male diagnosed with OA following three years of unsuccessful attempts at conception. The male had a history of bilateral inguinal hernia repair due to congenital bilateral absence of the vas deferens. Diagnostic assessments confirmed azoospermia. Microscopic epididymal sperm aspiration (MESA) was performed for sperm retrieval due to its efficacy and reduced postoperative pain, testicular atrophy, and decreased testosterone levels. The retrieved sperm was processed using SpermMobil media for intracytoplasmic sperm injection. Following successful fertilization, embryo transfers resulted in a positive pregnancy test. This case highlights the significance of specific treatment approaches for OA, specifically the effectiveness of MESA and SpermMobil in achieving successful outcomes in assisted reproduction technology for male infertility.
RESUMEN
Endometriosis and infertility are clinically associated. The therapeutic approaches for endometriosis, whether medical or surgical, yield distinct outcomes for a woman's potential for achieving conception, whether through natural means or with the aid of assisted reproductive technology (ART). In this case report, a 29-year-old female and her 32-year-old partner, married for the last five years, sought assistance at our fertility clinic after having one failed in vitro fertilization (IVF) cycle. The patient had a history of dysmenorrhea and deep dyspareunia, suggesting the presence of an ovarian cyst. Transabdominal ultrasound and laparoscopy confirmed the existence of ovaries with adhesions and a chocolate cyst measuring 8 cm × 6 cm in dimensions. Cystectomy of ovarian endometriomas enhances the rate of spontaneous conception and reduces pain. Moreover, it has the potential to enhance the outcome of IVF. The successful outcome achieved through ART, specifically the intracytoplasmic sperm injection cycle, underscores the importance of technological advancements in overcoming infertile barriers. This case report exemplifies the personalized and innovative approaches available to couples undergoing fertility treatment.
RESUMEN
The issue of infertility affects couples all over the world. Recurrent implantation failure (RIF) is caused by immunology, thrombophilias, endometrial receptivity, microbiota, anatomical anomalies, male factors, and embryo aneuploidy. An accurate evaluation of endometrial receptivity (ER) in cases of RIF during in-vitro fertilization (IVF) treatments is crucial to improve reproductive outcomes. To find her accurate window of implantation (WOI), a 34-year-old woman with unexplained RIF underwent an endometrial receptivity array (ERA) test. This case study examines her inexplicable RIF and reproductive results. The ERA test examined gene expression patterns in endometrial tissue to determine the receptive phase for proper embryo transfer. Primary infertility, ineffective intrauterine insemination (IUI), and several unsuccessful IVF rounds were all part of the patient's medical history. Her WOI determined the embryo transfer timing after getting the ERA test results. The patient's clinical pregnancy was successful. This particular case focuses on the potential of the ERA test to improve reproductive outcomes. However, when using this strategy, it is essential to consider difficulties, including invasiveness and related expenses. In this case, the positive results urge future research to apply customized WOI determination using the ERA test to improve the effectiveness of IVF therapies in patients with recurrent implantation failure. More extensive investigations and controlled trials are required to confirm these results and the broader applicability of this strategy. The ERA test is promising, but to provide a holistic approach to infertility care, it should be taken into account together with endometrial changes and elements of embryo-endometrial interaction that impact the success of implantation.
