Pregnancy in a hermaphrodite with a male-predominant mosaic karyotype

Do Sex and Gender Have Separate Identities?

The largely binary nature of biological sex and its conflation with the socially constructed concept of gender has created much strife in the last few years. The notion of gender identity and its differences and similarities with sex have fostered much scientific and legal confusion and disagreement. Settling the debate can have significant repercussions for science, medicine, legislation, and people's lives. The present review addresses this debate though different levels of analysis (i.e., genetic, anatomical, physiological, behavioral, and sociocultural), and their implications and interactions. We propose a rationale where both perspectives coexist, where diversity is the default, establishing a delimitation to the conflation between sex and gender, while acknowledging their interaction. Whereas sex in humans and other mammals is a biological reality that is largely binary and based on genes, chromosomes, anatomy, and physiology, gender is a sociocultural construct that is often, but not always, concordant with a person' sex, and can span a multitude of expressions.

Disorders of sex development and female reproductive capacity: A literature review

Disorders of sex development (DSD) are a wide-ranging group of complex conditions that influence chromosomal, gonadal, and phenotypic sex. The prevalence of DSD is very low, but affected patients deserve individualized management to improve psychological, sexual, and reproductive outcomes. This review aims to clarify the fertility potential of DSD patients who can be reared as females and their chance of becoming pregnant, especially using assisted reproductive techniques (ART). Due to the effects of DSD on internal and external genital organs, these conditions result in varying degrees of fertility potential. Fertility rate depends on the phenotype and is inversely related to the severity of the disorder. Reproductive endocrinologists and infertility specialists must be considered active partners of the interdisciplinary treatment team. With current advances in ART, pregnancy is more achievable in patients who were considered infertile at first glance. Due to the complexity of the medical management in DSD patients, more studies should be conducted to conclusively suggest the best choice for improving their fertility potential.Abbreviations: AIS: Androgen Insensitivity Syndrome; AMH: Anti-Müllerian Hormone; ART: Assisted Reproductive Technology; ASRM: American Society for Reproductive Medicine; CAH: Congenital Adrenal Hyperplasia; CAIS: Complete Androgen Insensitivity Syndrome; DHT: Dihydrotestosterone; DSD: Disorders of Sexual Development; FSH: Follicle Stimulating Hormone; GD: Gonadal Dysgenesis; ICSI: Intracytoplasmic Sperm Injection; IUGR: Intrauterine Growth Restriction; IVF: In Vitro Fertilization; IVF-ET: IVF and Embryo Transfer; LH: Luteinizing Hormone; MGD: Mixed Gonadal Dysgenesis; MRI: Magnetic Resonance Imaging; MRKH: Mayer-Rokitansky-Kuster-Hauser; US: Ultrasonography; HSG: Hysterosalpingography; PAIS: Partial Androgen Insensitivity Syndrome; PGD: Preimplantation Genetic Diagnosis; POR: P450 Oxidoreductase; PROM: Premature Rupture of Membranes; TS: Turner Syndrome; 17β-HSD III: 17β-Hydroxysteroid Dehydrogenase III; 21-OHD: 21-hydroxylase deficiency; 5α-RD-2: 5α-reductase-2.

Fertility outcome and information on fertility issues in individuals with different forms of disorders of sex development: findings from the dsd-LIFE study

OBJECTIVE

To investigate fertility outcome in individuals with different forms of disorders of sex development (DSD), if assisted reproductive technology (ART) was used, and the patients' satisfaction with the information they had received.

DESIGN

A cross-sectional multicenter study, dsd-LIFE.

SETTING

Not applicable.

PATIENT(S)

A total of 1,040 patients aged ≥16 years with different DSD diagnoses participated.

INTERVENTION(S)

A web-based questionnaire was filled out by all participants. The participants could chose to take part in somatic investigations including ultrasonography.

MAIN OUTCOME MEASURE(S)

Information on partner, number of children, ART, adoption and step-children, general health, presence of gonads and uterus, current education and economic situation, received information on fertility issues, and satisfaction with the information, was collected.

RESULT(S)

In the total cohort, mean age 32 years, 33% lived with a partner, but only 14% reported having at least one child including 7% with ART, 4% adopted. Only 3.5% of the total cohort had been able to reproduce without ART, most frequently women with congenital adrenal hyperplasia, and only 0.7% of participants with other diagnoses. Of the participants, 72% had received information on fertility, but 17% were not satisfied with the information.

CONCLUSION(S)

Fertility outcome is significantly reduced in all types of DSD; however, fertility potential should be assessed individually. The satisfaction with how fertility problems have been discussed can be improved. The care of patients with DSD is complex, should be individualized, and new treatment possibilities incorporated. A close collaboration in multidisciplinary teams is therefore essential to improve the situation for individuals with DSD.

The Effect of the Testis on the Ovary: Structure-Function Relationships in a Neonate with a Unilateral Ovotestis (Ovotesticular Disorder of Sex Development)

AIMS

To evaluate gonadal function in a newborn with suspected ovotesticular disorder of sex development (DSD).

METHODS

Gonadal function was evaluated at baseline and after gonadotropin-releasing hormone agonist (GnRHag) stimulation testing.

RESULTS

A full-term 46,XX neonate with genital ambiguity produced serum testosterone and anti-Müllerian hormone (AMH) levels appropriate for males within days, while serum estradiol remained prepubertal, both spontaneously and in response to GnRHag stimulation testing. Ovotesticular DSD was diagnosed at laparoscopy: the left gonad was an ovotestis and the right gonad an ovary arrested at the primordial follicle stage of development. Mosaicism for an isochromosome of the Y short arm in 6-18% of gonadal cells was demonstrated. After ovotestis removal at 3 weeks of age, serum AMH became low within a month, but the elevated testosterone was slow to resolve, apparently from ovarian androgenic hyperfunction coincident with ovarian estrogenic hyperfunction and an adult degree of ovarian development. Ovarian morphology and function gradually normalized as neonatal minipuberty waned.

CONCLUSIONS

In a neonate with genital ambiguity due to ovotesticular DSD, testicular AMH and testosterone production respectively appear to account for the initial arrest of ovarian development and subsequent rapid hyperfunction of the contralateral ovary after ovotestis removal.

A case of omphalo-ischiopagus (dicephalic dithoracic abdominopagus tetrascelus tetrabrachius) in lambs

This case report describes a rare occurrence of asymmetrical conjoined twinning in lambs in Makurdi (Benue state), Middle Belt region of Nigeria. The conjoined twins were delivered normally by a multiparous ewe of about three and a half years old; the female twins had two complete set of limbs. Barium meal and X-ray revealed abnormalities of the skeletal, digestive, urinary and reproductive systems. This condition is rare in sheep and is to the best of our knowledge the first report of omphalo-ishiopagus (dicephalic dithoracic tetrabrachius) twinned lambs. The condition always leads to death of the twin lambs due to various physical abnormalities.

Successful monozygotic twin pregnancy fathered by a male 46,XY true hermaphrodite

This report presents an unusual case of absolute non-obstructive azoospermia revealed to be a male 46,XY true hermaphrodite who was successfully treated to father healthy monozygotic twins. A 27-year-old infertile male with non-obstructive azoospermia previously underwent an unsuccessful testicular sperm extraction procedure and refused donor sperm insemination.Revising the patient’s old records revealed that he was born with ambiguous genitalia. He had a 46,XY karyotype and was raised as a male. During childhood he underwent ambiguous genitalia reconstruction, right orchiopexy and left salpingo-oophorectomy that revealed a gonadoblastoma. A new treatment was employed performing testicular fine needle aspiration leading successfully to a monozygotic twin pregnancy. As far as is known, this is the first reported case of healthy twins fathered by a male 46,XY true hermaphrodite.

Pregnancy in true hermaphrodites and all male offspring to date

BACKGROUND

There are 11 reported cases of pregnancy in true hermaphrodites, but none with advanced genetic testing. All known fetuses have been male.

CASE

A true hermaphrodite with a spontaneous pregnancy prenatally known to have a remaining portion of a right ovotestis, delivered a male neonate. The mother has a 46, XX karyotype with polymerase chain reaction demonstrating low levels of the Yq12 sequence. Postpartum androgen levels were normal.

CONCLUSION

Partial removal of testicular tissue may enhance fertility in hermaphrodites, and there may be a genetic basis for the progeny to be male.
