Surrogacy is an important method of assisted reproductive technology wherein a woman carries pregnancy for another couple. Number of couples around the world require surrogacy services for various reasons. Although this arrangement seems to be beneficial for all parties concerned, there are complex social, ethical, moral, and legal issues associated with it. It is these complexities that have made this practice unpopular in many parts of the world. Surrogacy in India has had its own journey from India becoming popular as a surrogacy center since 2002 to the Surrogacy (Regulation) Bill, 2016, which would restrict the option of surrogacy for many. Surrogacy is an important medical service for all those couples who would otherwise not have been able to produce a child. Surrogacy would be practiced harmoniously if delicate issues associated with surrogacy will be addressed properly through appropriately framed laws which would protect the rights of surrogate mothers, intended parents, and child born through surrogacy.

Bone marrow-derived cell (BMDC) therapy has numerous applications as potential biological cells for use in regenerative medicine. Here, we present an original case of endometrial atrophy associated with genital tuberculosis in a woman who achieved a live birth with BMDC. This 27-year-old woman came to our center with endometrial atrophy and primary infertility. She had a past history of genital tuberculosis and amenorrhea. Her husband’s semen quality was normal. The patient was counseled for hysteroscopy due to thin endometrium and advised in vitro fertilization (IVF) with donor eggs in lieu of poor ovarian reserve. Several attempts of IVF with hormone replacement therapy (HRT) were made, but the desired thickness of the endometrium was not achieved. Uterine artery injection of BMDC through interventional radiology was given, followed by HRT for three months, which resulted in improved endometrium. This was subsequently followed by IVF with donor egg. The treatment resulted in the conception and delivery of a 3.1-kg baby boy through lower segment caesarean section with no antenatal, intranatal or postnatal complications. Recently, there has been massive interest in stem cells as a novel treatment method for regenerative medicine, and more specifically for the regeneration of human endometrium disorders like Asherman syndrome and thin endometrium, which was the reason behind using this strategy for treatment.

Aim In recent past, many studies had come up with the combination of time-lapse (TL) imaging of embryo morphokinetics as a noninvasive means for improving embryo selection and in vitro fertilization (IVF) success. The primary objective of the study was to find out if there is significant variation in morphokinetics of embryos with different implantation potential and also to study the effect of sperm freezing on time points of embryogenesis events in embryos with implantation potential. Materials and methods Kinetic data and cycle outcomes were analyzed retrospectively in 142 patients who had undergone IVF/intracytoplasmic sperm injection (ICSI) cycles using semen with normal parameters and embryo transfer (ET) on day 3. For the surety of specificity of morphokinetics, only cases with single ET cycles were included in the study. Timing of specific events, from the point of ICSI, was determined using TL imaging. Kinetic markers like time to syngamy (t-pnf), t2, time to two cells (c), 3c (t3), 4c (t4), 5c (t5), 8c (t8), tMor, CC2, CC3, t5–t2, t5–t4, s1, s2, and s3 were calculated. The cleavage synchronicity from the 2–8 cell stage (CS2–8), from 4 to 8 cell stage (CS4–8), and from 2 to 4 cell stage (CS2–4) were calculated as defined elsewhere. Deoxyribonucleic acid replication time ratio (DR) was also included in the comparison. Analysis of variance test was used for comparison of the mean timing of cell division and cell cycle intervals. Results Morphokinetics t-pnf, t2, t8, CC2, S2, S3, CS2–8, CS4–8, and CS2–4 differed significantly between embryos with and without implantation potential, when embryos were developed using fresh semen, while t3, t4, t5, CC2, S2, t5–t2, CS2–4, and DR differed significantly between the embryos with and without implantation potential when frozen semen was used. No significant difference was found in mean value of any of the above-stated parameters when comparison was done between implanted embryos fertilized by either fresh or cryopreserved sperm. Conclusion Many morphokinetics parameters of embryogene­sis vary significantly between embryos with different ability to implant; therefore, the criteria developed in our IVF lab can be useful for selection of suitable embryo even at day 3 of development with more chances of implantation. Clinical significance Study indicates necessity of development of individualized selection model based on morphokinetics for every IVF lab and also confirms freezing as an important tool for fertility preservation of males as it does not affect events of embryogenesis.
