The SRY-negative variant is exceptionally rare and invariably associated with non-obstructive azoospermia. Awareness of this condition is important for infertility specialists, as genetic evaluation can establish an accurate diagnosis early in the workup and guide appropriate counselling. We report the case of a 30-year-old man who presented with primary infertility. Clinical examination revealed small testes with an otherwise normal male phenotype. Semen analysis confirmed azoospermia, and hormonal testing showed elevated gonadotropins with borderline testosterone levels. Imaging demonstrated reduced testicular volume without malignant features. Karyotype analysis revealed a 46,XX constitution, and molecular testing confirmed the absence of the SRY gene, establishing the diagnosis of SRY-negative de la Chapelle syndrome. Based on these findings, the patient was counselled regarding the futility of autologous sperm retrieval and was advised on donor-assisted reproductive options. Written informed consent was obtained for publication. This case highlights the value of incorporating genetic testing into the evaluation of non-obstructive azoospermia. Early recognition avoids unnecessary invasive interventions such as testicular sperm extraction and allows couples to receive timely counselling about realistic reproductive options. Although natural fertility cannot be achieved, assisted reproduction with donor sperm offers a viable pathway to parenthood.

However, IVF pregnancies are associated with potential obstetric complications, notably placenta accreta spectrum (PAS), which necessitates early diagnosis and a multidisciplinary approach to safeguard maternal-fetal health. This systematic review involved a comprehensive search of databases such as PubMed, Cochrane Library, BVS, Embase, Web of Science, and Scopus using specific terms related to IVF and PAS. Original studies comparing spontaneous pregnancies to IVF pregnancies were included, while case reports and non-peer-reviewed articles were excluded. Data extraction was standardized, and study quality was assessed using the Newcastle-Ottawa tool. The analysis covered thirteen articles involving 252,295 assisted reproductive technology pregnancies and over 16 million spontaneous pregnancies. A key finding is the increased risk of PAS in IVF pregnancies, with some studies indicating that frozen embryo transfer (FET) poses a higher risk than fresh embryo transfer. Additional complications include hypertension, preeclampsia, and intrauterine growth restriction (IUGR). Interestingly, some research suggests a lower Intensive Care Unit admission rate for women with placenta accreta after IVF compared to those with spontaneous conception. This indicates that while assisted reproductive technology is an independent risk factor for PAS, it presents a unique risk profile.

The existing literature indicates that many professionals are not prepared to assist transgender individuals, often supporting a heteronormative view of sexuality and reproduction. This case report explored whether the experience of pregnancy impacted the gender identity and experience of masculinity in a transgender man. A clinical case study methodology was employed. Initially, it was hypothesized that pregnancy would neither compromise the participant's male identity nor weaken his experience as a transgender man. One transgender man expressed a desire to carry his genetic child. Our findings revealed that he began to enjoy the experience and was positively reconnected with his pregnant body by the sixth month of pregnancy. The psychic elaboration of the fantasy that \"carrying a pregnancy is not a man's thing\" made him reconsider the feelings of impotence and vulnerability that are traditionally attributed to the females. He had a satisfactory experience with the healthcare team. He actively assumed the role of \"father-birthgiver,\" demonstrating that fathers are also capable of sensitively responding to a baby's emotional needs. Although it mobilized complex psychological processes, the pregnancy experience did not cause identity disruption.
